How to brief and produce an event teaser trailer

You've booked someone to make the trailer. The reference videos look good, the event goes on sale soon and everyone agrees it should feel exciting. Then the first edit arrives. It's beautifully shot, but you can't tell what you're being invited to. Your colleague wants more crowd footage. The performer wants a longer extract. The editor wants to know which instruction to follow.

An event teaser trailer brief should prevent that conversation from happening so late. Before anyone films, agree who the trailer is for, what they need to understand and what you can show to support the invitation. Then approve the story, the production plan and the finished files in separate stages. You'll make better decisions when changing a sentence still means editing a document rather than booking another shoot.

For a paid event, the trailer also needs a commercial reason to exist. Perhaps prospective buyers don't understand the format. Perhaps they recognise the performer but haven't heard about this particular show. Be specific about the problem you're paying production to solve. More cinematic footage won't necessarily answer it.

This guide follows a trailer commission through the brief, shoot preparation, edit rounds and delivery. We'll use a fictional concert to make the choices concrete. The example timings, costs and quantities are invented planning assumptions, not market rates or claims about what a trailer will sell.

Decide whether you need a new production

Start by looking at what you already have. You might have an approved performer recording, good footage from the previous edition and an editor who can assemble a clear invitation. If that material answers the buyer's question, commissioning a new shoot could add cost without adding useful information.

Our guide to making an event promo video covers a simpler editing job. This guide is for the point where you're commissioning a production and need to agree what someone else will deliver. You can use the same process with an internal team, especially when several people have approval rights.

Ask what the new production would let you show. A rehearsal can reveal how a musical programme sounds. A demonstration can explain the activity included in a workshop. A host can make an unfamiliar format easier to understand. Those are useful answers. "We haven't posted a trailer this year" is a weaker reason to spend.

Also check whether the offer is ready. If the venue, programme or ticket release is still uncertain, identify what can be said accurately now. You might commission a date announcement and make the fuller trailer later. Don't pay an editor to hide missing event decisions behind fast cuts.

A first event can have a good trailer without pretending it has happened before. Film a rehearsal, explain the format or show the actual location with permission. If you use archive material, make its relationship to the coming event clear. Footage of a former headliner shouldn't leave viewers believing that person is booked again.

Write the buyer's question before the creative brief

For our example, imagine a concert called Close Listening. A string quartet will play complete pieces, with short introductions explaining what to listen for. The organiser wants to reach people who enjoy live music but haven't bought a chamber-concert ticket before. The event is seated, and the next date is confirmed.

The buyer's uncertainty is straightforward. "Will I enjoy this if I don't already know the music?" A useful trailer lets someone hear the quartet and understand the introductions. A montage of instruments, applause and venue lighting might suggest quality, but it could leave that uncertainty untouched.

Write the intended answer in ordinary language. For this fictional event, it might be: "You can come without knowing the pieces. The musicians introduce what you'll hear, then play the music in full." The production team now has something to demonstrate and a claim the event owner can verify.

Decide what the viewer should do next. Here, tickets are on sale, so the trailer invites them to see the programme and book the confirmed date. If you were collecting interest before ticket sales opened, the action would change. That affects the script, final frame and destination, so settle it before approving the treatment.

Don't ask one short trailer to answer every possible concern. Accessibility arrangements, transport and refund conditions still need accurate information on the event page. Include a detail in the film when it's central to the invitation or necessary to avoid a misleading impression. Otherwise, make sure the next page answers it clearly.

You can develop those audience decisions through our event content marketing guide. For the commission itself, reduce them to an instruction someone can produce: show the introductory explanation, let us hear the quartet, and invite a first-time listener to this date.

Use a brief that a supplier can price

Your event teaser trailer brief should be short enough to use during production and detailed enough to stop important assumptions becoming surprises. Separate confirmed facts from creative suggestions. The organiser owns the accuracy of the event offer; the filmmaker proposes how to communicate it.

Here is a worked brief for Close Listening. Treat it as a structure to adapt, rather than a package every event should buy.

• The audience is local adults considering their first chamber concert. The main uncertainty is whether they need prior knowledge to enjoy it.

• The trailer must show a musician introducing an idea and the quartet playing the related passage. The event owner confirms that introductions are part of the advertised show.

• The invitation is to book the named date at the named venue. The organiser supplies the approved programme, ticket destination and exact event details.

• The proposed production is a rehearsal shoot, followed by one main 30-second edit and one distinct 15-second reminder edit. These are choices for this campaign, not ideal lengths for every channel.

• Both edits need vertical 9:16 and horizontal 16:9 versions. Each needs an approved captioned export and a clean export without captions or event-information graphics. The organiser separately requests caption files and an approved transcript.

• One marketing lead consolidates feedback. The event owner approves facts, the musical director checks the performance extract and the marketing lead authorises release.

• The quote must cover preparation, capture, editing, the agreed versions, music permissions, accessibility work and delivery. Anything excluded must be stated before booking.

For that example, two edits in two shapes with two export treatments produce eight video files. They remain two editorial ideas. This distinction helps when comparing quotes. "Eight videos" could otherwise mean eight separate stories, eight exports of one story, or something in between.

Attach the current event facts and any mandatory wording. Say which facts are approved and who can change them. If a sponsor must appear, provide the actual obligation and approved artwork. "Add our partners somewhere" leaves the editor guessing how much time and space to reserve.

Ask the supplier to confirm the brief back in their proposal. You want to see their interpretation, the work included and what they need from you. Resolve differences before accepting the price. A quote based on supplied footage won't become a rehearsal shoot because the original email mentioned cameras.

Choose someone who can deliver this particular film

A showreel tells you how a supplier presents their best work. Ask to see a complete commission with a similar purpose, including an ordinary spoken explanation and the final invitation. You need to know whether they can make the experience understandable, not only whether they can make a performance look impressive.

For Close Listening, ask how they would record the quartet and the spoken introduction. A useful response should explain the audio approach, the time needed and who will judge the musical extract. You don't need to prescribe the equipment. You do need confidence that the supplier has understood why sound is central to this assignment.

Find out who did what in the examples. The person pitching may have directed the shoot while another person edited it. That's fine, provided the proposed team covers your job. Confirm who will attend, who will edit and who remains responsible for delivery if a collaborator becomes unavailable.

Ask about a difficult approval they handled. You want to hear how they identified the disagreement, explained its effect and reached a decision with the client. A supplier who asks you to resolve the audience before filming is helping the production. Promising unlimited changes without discussing time or scope gives you less useful information.

When proposals arrive, compare them against your brief and discuss any exclusions. If a supplier proposes a simpler treatment, judge whether it still answers the buyer's question. You might get a more convincing invitation by recording one clear musical explanation well than by spreading the same budget over several locations.

Approve a treatment and a script before filming

A treatment is a short description of how the film will tell the story. It might describe a musician speaking directly to the viewer, followed by a musical passage and an invitation. It should explain the approach well enough for you to judge whether it serves the brief, without requiring every shot to be predetermined.

For Close Listening, the proposed opening could be the musician saying, "You don't need to know this piece. Listen for what happens when the melody changes hands." We then hear that moment played. The invitation explains that short introductions are part of the concert. That is a more testable idea than "an elegant film celebrating musical connection."

Read the spoken words aloud at a comfortable pace. Include pauses, the performance extract and the event information in the intended running time. A script that fits only when somebody races through it hasn't fitted. Cut a secondary point before asking the performer to speak unnaturally.

Ask for a simple sequence showing what viewers see and hear. It can be written as successive paragraphs with approximate timings. Storyboards can help when framing or animation is difficult to explain, but an elaborate presentation isn't necessary for a straightforward rehearsal film.

Watch for a promise the footage can't support. If the opening says every guest gets a chance to ask questions, the event must actually offer that. If it says the show is an hour, confirm whether that includes introductions and any interval. The production team should flag ambiguity; the event owner has to resolve it.

Approve the concept and exact factual wording before the shoot. Keep room for better performances or useful discoveries on the day. What you're avoiding is a fundamental disagreement about the audience or offer after everyone's been filmed. Name who can approve a proposed departure from the script while the crew is working.

Turn the script into a practical shot plan

The shot plan translates the agreed story into footage the editor will need. For each part, ask what must be visible, what must be audible and what could stop you getting it. That turns a vague request for "plenty of coverage" into preparation the crew can use.

In the concert example, the musician's introduction needs intelligible speech. The demonstration needs a usable recording of the music, with enough continuous playing to preserve the phrase. The invitation needs accurate event details. Close-ups of fingers are useful supporting material, but they can't replace the explanation or a coherent musical extract.

Film with every agreed shape in mind. A wide shot of four musicians may become unusable when cropped vertically. The supplier might plan separate compositions, a closer pairing or another way to explain the same passage. Ask to see that solution before assuming one camera position will serve every export.

Check the location in advance, remotely or in person as the job requires. Find out whether you can control background sound, where equipment can go and how long setup takes. A beautiful rehearsal room beside noisy building work may be a poor place to record a quiet explanation. Tell the supplier what you know and ask what they still need to assess.

Prepare the people too. Send the purpose and proposed wording early enough for the musician to question anything inaccurate. Ask them to explain the idea naturally rather than memorise promotional language they would never use. If their better explanation changes the promised format, get the event owner to approve it before filming.

Keep an alternative for each indispensable shot. If the venue isn't available, can you still demonstrate the musical idea in the rehearsal space? If one performer can't attend, can the agreed invitation remain accurate? An alternative has to support the same offer. Unrelated archive footage won't solve a missing demonstration.

Make the shoot work around the people and the place

A call sheet is the practical plan for the shoot day. It tells the crew and contributors where to arrive, when they're needed and whom to contact. Include access arrangements, setup, breaks, filming windows and the time you must leave. Keep private contact details within the working team.

For a rehearsal production, agree whether you're filming an existing rehearsal or booking a separate session. Those are different demands on the musicians. Repeating the same short passage for camera angles takes time and may interrupt musical preparation. Price and schedule that work honestly instead of assuming the performers can absorb it.

Name one organiser who can answer questions during the shoot. They should have the authority to confirm event facts and approve agreed spending within a limit. If every small change waits for someone who is unavailable, you can lose the filming window while the crew is ready to work.

Ask the supplier to identify the work needed before recording starts. Sound checks, lighting and framing are production time. So is checking that the intended vertical version keeps the important action visible. Don't schedule the contributor to arrive for a ten-minute slot if the crew still needs to set up around them.

If you film during an audience-facing event, protect the experience people paid for. Agree filming positions and restrictions with the venue and operational team. Don't move attendees, block routes or repeat a programme moment simply because the shot would be better. Our guide to photo and video permission at events covers the separate questions around identifiable people and publication.

Before leaving, have the crew check that the essential speech and performance material are usable. This doesn't replace proper backup and editing checks, but it can catch a silent microphone or missing introduction while another take is possible. Confirm who is protecting the files and when the organiser can expect the first update.

Clear the intended uses before building the edit around them

Music permissions deserve attention before the editor times every cut to a track. WIPO's rights-clearance guide for filmmakers distinguishes rights in the musical composition from rights in a particular recording. It also explains why the intended use, including promotion, matters when obtaining permission. A performer supplying a recording doesn't by itself establish that every relevant right has been cleared.

For Close Listening, name the composition, the recording and the proposed promotional uses. Ask the responsible rights adviser or supplier to confirm what permissions are needed for that material and territory. Even where a composition is out of copyright, don't assume a modern recording or arrangement has the same status. Keep the written permissions with the project.

Platform music libraries also need a specific check. TikTok's Commercial Music Library guidance, updated in July 2026, directs users to select campaign regions and filter usable placements. Choose against the actual campaign. Finding a song inside an app doesn't establish permission to export it into every other advertising channel.

Explain your uses when requesting the quote. Are you posting on your accounts, running paid ads, supplying partner accounts or letting a venue publish the film? For how long, and in which markets? If partners need to edit or advertise with the material, say so. They may need permissions that your own organic posting doesn't require.

Keep ownership and delivery separate. The UK Intellectual Property Office's guidance on licensing and transferring copyright explains that a licence sets permitted uses and that a copyright assignment requires a written, signed agreement. That's UK guidance; establish the applicable terms for your commission rather than treating payment of an invoice as a complete rights agreement.

Ask separately about source footage, editable projects, fonts and third-party material. Receiving the finished export may be enough for a short campaign. If you expect another editor to change dates next year, request an editable handover and establish which supporting assets can transfer. Don't buy a project file nobody can open or lawfully reuse.

Set a complete budget before comparing production quotes

Send the same brief to the suppliers you're considering. Then compare what each will actually deliver. A lower quote may assume you supply all footage, clear all music and handle captions. A higher one may include those jobs. Ask about the difference before concluding someone is expensive.

Here is an invented budget in US dollars for Close Listening. Preparation costs $300, the shoot $700, editing $600, and the agreed exports, captions and transcript $200. Allow $200 for the agreed music permissions. The supplier total is $2,000, assumed to include applicable purchase taxes. These are illustrative allocations, not quoted industry prices. Assume the shoot allocation covers location use, crew, equipment and the quartet's agreed filming time. Confirm the actual inclusions with your supplier.

The organiser also allows ten staff hours for briefing, coordination and approvals, valued at $30 an hour. That adds $300 of staff time, for a combined production cost of $2,300. If those hours use existing salaries, the additional cash payment is still $2,000. If they require extra payroll, include that in the cash plan too.

Suppose the campaign also needs $600 of advertising. Production, staff time and advertising then total $2,900. For this example, each additional paid admission leaves $40 after ticket taxes and selling costs, and costs another $4 to serve. It contributes $36 towards the campaign and existing event costs. Those assumptions aren't Loopyah fees or a typical concert margin.

You need 81 genuinely additional paid admissions to cover $2,900 at that contribution. Eighty leave $2,880, which is $20 short; 81 leave $2,916. That does not make the whole concert profitable. Ordinary venue, artist and business costs still need covering separately. It tells you what the combined campaign cost must recover.

The example has 180 audience places, ten reserved for invited guests and 60 paid admissions expected without the campaign. That leaves 110 places for additional sales, so 81 is physically possible. Whether the campaign can create that demand is unproven. Budget the invited guests separately and don't count their places as available paid inventory.

Compare a smaller commission against the same objective. You might already have suitable performance footage and need only a filmed introduction. If that answers the buyer's question, ask for that version of the quote. Protect the explanation, rights and usable delivery before cutting essential work to preserve an elaborate visual concept.

Work backwards from the release date

The release deadline is when the approved trailer must be usable in the campaign. It isn't the day the first edit reaches your inbox. Allow time to download the delivery, test the exports and check the publication destination before advertising is due to start.

For the fictional concert, imagine a release on Friday. You might require final files by Wednesday, the polished approval version the previous Friday, and the rough cut earlier that week. The shoot and script approval must happen before those dates, with enough time for the actual workload. This is an example sequence to negotiate with the supplier, not a universal production timetable.

Put your own review periods on the schedule. A supplier can promise a first edit on Tuesday, but that doesn't help if the event owner won't look at it until the following Monday. Confirm availability before booking the deadline. If the musical director must approve the extract, reserve that person's time as well.

Identify decisions that can hold everything up. Music clearance, contributor availability and an unconfirmed sponsor message may matter more than the time it takes to export the file. Assign an owner and due date to each. If a required permission is still unresolved, use an approved alternative or change the release plan.

Agree what happens when either side misses a date. A late script approval may move the shoot or incur a rush charge. A supplier delay may affect booked advertising. Record the notification process and contractual consequences while planning the commission. Don't assume everyone can recover lost time by working overnight.

Also agree what happens if the event is postponed or cancelled. Ask which preparation remains payable, whether a shoot can move and when a new booking would need another quote. Establish what you receive for completed work and whether you can use it for a replacement date. A paid deposit doesn't answer those questions on its own; the agreement should.

Separate the event's cancellation from a production problem. If the concert goes ahead but the contributor becomes unavailable for filming, you need an agreed alternative or a revised trailer plan. If the supplier cannot attend, you need to know who arranges a replacement and whether you can approve that person. Price any stronger backup arrangement you actually require.

Tell partners when their approval is needed and what happens if it arrives late. A sponsor who must approve its own logo doesn't automatically need authority over the entire story. Define the relevant checks before the schedule is agreed. If a partner has wider contractual approval rights, allow the time those rights require rather than hoping they won't be exercised.

Review the rough cut for the story

The rough cut is an early edit that lets you judge the sequence before all the finishing work is complete. The colour, music balance or graphics may still be temporary. Ask the supplier to label those unfinished elements, so your team knows what feedback is useful at this stage.

First watch it as someone unfamiliar with the event. Can you tell what the invitation is? Does the explanation address the uncertainty in the brief? In Close Listening, the viewer should understand that introductions are part of the concert and hear something that makes attending appealing. If either is missing, fix the sequence before discussing the logo animation.

Then check whether the performance has been represented fairly. The musical director should review the proposed extract for this specific use. An edit can distort a demonstration by removing its setup or joining unrelated moments. Similar problems arise with speaker clips and workshop instruction. A pleasing pace doesn't excuse changing what someone meant.

Bring feedback from the relevant people into one response. The musician checks the performance, the event owner checks the offer and the marketing lead judges the communication. They don't all need to direct the edit. Resolve conflicting requests internally and send the editor a decision they can act on.

Use exact moments in the video when commenting. "At 00:08, the word 'introductions' disappears before I can read it" identifies a problem. "It needs more energy" doesn't explain whether the issue is slow speech, unrelated footage or an audience mismatch. Describe the effect you need, then let the editor propose the production solution.

Approve the story before requesting final colour, sound and all alternate versions. If the main sequence still needs rebuilding, producing every crop multiplies work that may be discarded. Confirm what rough-cut approval means in your agreement, including which later corrections remain included.

Distinguish a correction from a change of direction

Revision terms should tell both sides what happens when the first edit needs work. Agree how many creative feedback rounds are included, when feedback is due and what happens after approval. Also establish the process for correcting work that doesn't match the agreed brief.

A misspelled venue name is a factual correction. A promised caption file that wasn't delivered is a missing item. A distorted audio export is a technical fault. Handle those against the accepted scope and contract. They are different from requesting a new interview because a colleague now prefers another opening.

Suppose the Close Listening script was approved around first-time listeners. After the rough cut, the organiser decides it should target experienced musicians and explain the repertoire in detail. That changes the audience and story. The supplier may need another script, different footage and more editing. Ask for the cost and delivery effect before authorising that work.

Don't use the revision allowance as a substitute for agreeing the idea. "Two rounds" becomes expensive when your team treats each round as permission to reconsider everything. Consolidated feedback should resolve the current stage, with any unresolved decision explicitly identified. Silence from a required approver shouldn't be recorded as approval unless you've expressly agreed that process.

Keep a short change record. It needs the request, the person approving it, the additional price if any and the revised deadline. If you can't afford the change, ask what can be removed or retained. The useful negotiation is about the work and outcome, rather than demanding the same expanded scope for the original fee.

Build accessibility into the delivery

Specify accessibility work when commissioning the trailer. W3C's planning guidance for audio and video recommends including requirements in project briefs and contracts. It explains the roles of captions, descriptions and transcripts according to the content. Decide what your audience and applicable requirements need before the edit is finished.

For the concert example, accurate captions should convey the musician's speech and relevant sound information. The transcript should include essential visual information someone would otherwise miss, such as the event details shown only on the final frame. Where audio description is needed, plan how it will work with the music and speech. Captions alone don't make every part of a video accessible.

Ask a named person to check generated captions against the actual audio. Pay attention to names, unfamiliar terms and timing. "Close listening" could become a sentence fragment in automatic transcription when it's actually the event name. The final version needs a human decision about what was said and how to present it clearly.

Check readability on a phone at normal playback speed. Text should remain legible over the footage, stay visible long enough to read and avoid covering the demonstration. Preview the actual destination, where controls can obscure parts of the image. A readable file in an editing window may behave differently when posted.

Agree which versions contain captions in the picture and which use a separate caption file. The latter may help where the destination supports selectable captions; it needs testing after upload. Keep the approved wording consistent across the video, caption file and transcript. Otherwise a late date correction can leave one version announcing the wrong event.

Accept the final delivery against the brief

Final approval of the edit and acceptance of the delivery are connected but separate checks. You can love the film and still be missing the horizontal version, the caption file or the permission to use it in ads. Check the whole package before treating the production as complete.

For our example, count the eight agreed video exports. Open both editorial ideas in both shapes and check the captioned and clean treatments. The clean export here removes captions and event-information graphics; it still contains the cleared performance audio. If you need separate audio tracks or a version with no added music, request those separately and define what can transfer.

Download the files to storage your business controls. Don't rely solely on a review link that may expire. Check that the files open, play to the end and have the agreed picture and sound quality. Ask the supplier to name the approved version and mark earlier drafts clearly so nobody accidentally publishes them.

Then test the intended publication. Check the image crop, speech level, caption timing and final invitation. Confirm the event page on a phone and make sure the link leads to the right date. Check every price or deadline still shown in the video. A release delayed by a week may need updated information even when the edit itself hasn't changed.

The handover should include the agreed rights information, caption files, transcript and any contracted editable material. Record limitations, expiry dates and permitted partners. If the supplier retains an archive, confirm how long, what it contains and what retrieval would cost. Your own verified delivery should cover the assets you need to run the campaign.

Settle payment under the booking terms, including approved extras. If something remains outstanding, identify it precisely and agree the correction process. Don't invent new acceptance conditions after delivery, and don't declare the job finished while an essential contracted item is still missing.

Release it with a working route to buy

The trailer should send viewers to the event it describes. Repeat the important promise on the ticket page, with the programme, date and practical conditions needed to purchase. Someone who likes the musician's explanation shouldn't have to search through unrelated editions to find the advertised concert.

Use existing ticketing reporting where it answers the question. Loopyah's ticket-selling tools show sales by source, helping you see which posts and emails sold tickets. Review that information alongside your publishing record and campaign costs. It can help guide the next decision without asking the production supplier to maintain a separate record of every buyer.

If you also use Google Analytics, its campaign URL guidance explains how campaign tags identify referring traffic and how a content tag can distinguish creative versions. Agree consistent labels for the main trailer and reminder. Test your actual setup; adding a label to a link doesn't automatically establish completed-purchase tracking across your entire buying journey.

Assign someone to maintain the campaign after release. They need to know which files are in use, where partners posted them and when information becomes outdated. If the advertised release sells out, stop or replace versions promoting it. Keeping the editable master helps only when somebody is responsible for making the change.

Review what the trailer changed before commissioning the next one

Start with the question in the brief. Did people understand the concert format? Look at relevant questions, the response to the explanation and what happened after viewers visited the ticket page. Then examine sales evidence and costs. A high completion rate can tell you people watched; it doesn't tell you the production paid for itself.

For Close Listening, compare results with the earlier assumptions. Production, staff time and advertising needed 81 additional admissions at $36 each to cover their $2,900 combined cost. If you can reasonably assess only 50 as additional, they leave $1,800, or $1,100 less than that cost. Review that honestly rather than counting every sale after publication as the trailer's work.

Reported attribution and additional sales are different questions. Someone might click the trailer shortly before buying a ticket they already intended to buy. Another person might watch it, return through a later email and purchase. Keep the reporting method consistent and explain its limits. Don't add several platforms' credited purchases together as though each represents a different buyer.

If you test openings, keep the offer and viewing conditions comparable where practical. A musician-led version shown to new buyers weeks before the concert and an urgent reminder sent to regulars the day before aren't a clean test of the opening. Small sales counts also limit what you can conclude. Record what you changed and what remains uncertain.

Review production as well as promotion. Did the brief prevent rework? Did the shoot produce the essential material? Were approvals late? Could your team use the delivery without another editing job? Those answers tell you whether to change the next commission, even when sales evidence can't isolate the film's contribution.

Before rebooking, send the supplier a revised brief grounded in that review. You may need a clearer demonstration, fewer versions or an earlier factual approval. Agree those changes, confirm what the price includes and reserve the review time. The next trailer should begin with an event decision you can explain and a production plan both sides understand.
