3D Animation for Trade Shows: Booth Loop Length, Silent Playback, and Planning Back from the Show

Key points

• Set the length by where the screen sits. Published estimates (as of November 2026) put an aisle-facing loop at about 10–30 seconds and most booth screens at 30–90 seconds (dmakproductions.com, morphic.com).
• Assume nobody hears it. Automate 2026's rule of thumb is 85 decibels at the aisle (ordering.ges.com), and IAAPA Expo asks for 75 decibels sustained (iaapa.org).
• At the pace of our 53 samples, 15 seconds holds about 35 words and two scenes.
• Processing takes hours, and your review sets the calendar. The table below starts three weeks out. It is a planning guide, not a delivery promise.
• A shorter video doesn't cost proportionally less. A 15-second Standard video with two revisions measured about 3,500 credits ($35).

How long should a trade show video be?

Where the screen sits	Published length	Sound	What it has to do
Facing the aisle	10–15 seconds for high-traffic aisles (dmakproductions.com), 10–30 seconds per cycle (morphic.com)	Off	Say what the product is in the first seconds. One idea per scene
Inside the booth	30–90 seconds for most booths (dmakproductions.com), 60–120 seconds (videoeditingcompany.com)	Off or ambient	Show how the machine works. Make sense from any starting point
Meeting table or demo station	No published range we could confirm. We'd plan 1–3 minutes	On, with dedicated headphones if the floor is loud (videoeditingcompany.com)	Staff start it from the top, so narration can carry the detail

These are vendors' recommendations, and they disagree: Epipheo's trade show videos run 30 seconds to 2 minutes (epipheo.com). We found no independent study of booth loop length.

What fits in each length

Calculated from the medians of our 53 English samples. Finished length lands within about ±10% of what you set.

Length	Narration and captions	Scenes
15 seconds	About 35 words	2
30 seconds	About 70 words	3–4
60 seconds	About 140 words	7

Fifteen seconds is a product name and one claim. The feature list belongs in a separate video for inside the booth.

Making it work with the sound off

Show floors limit sound, and the limits vary. Automate 2026's manual measures its 85-decibel rule of thumb from the aisle right in front of the booth, and warns that music played in a booth may fall under copyright law, at the exhibitor's responsibility. IAAPA Expo, an attractions-industry show, allows peaks to 85 decibels and lists a noise penalty of three years of exhibit seniority plus a $600 fine. Check your own exhibitor services manual.

1. Read the storyboard with the narration covered. If the visuals and on-screen words don't carry the point, fix it before the build.
2. Put anything read from a distance in the headline, not the caption. Captions run line by line at the bottom of the frame, where a crowd can block them. One guide suggests text legible from 8–10 feet and 5–8 words per screen (videoeditingcompany.com). Headlines in our samples have a median of three words.
3. Make every scene stand alone. People join midway, so avoid lines that lean on the previous scene.
4. Give one moving shot the main job. In the DR-5 power driver sample (a fictional product), the "What's Inside" chapter turns the shell see-through and labels the parts, so it reads without sound.
5. End on the product name. Looping is a setting on your media player. We haven't tested a request to remove the seam between the last and first frames.
6. Test it muted. Watch the 540p preview with the sound off, from where people will actually stand.

Captions in 3DCG Video AI are part of the MP4, which is what D-MAK recommends for booth screens over a player's caption toggle (dmakproductions.com). You mute at the monitor or player. We don't have a silent-loop sample yet: all current samples are 16:9, about a minute long, with narration.

A request you could paste into the chat: "This runs muted on a 16:9 monitor facing the aisle, looping all day. Make it 30 seconds, with one idea per scene and headlines of five words or fewer. Show the product name and what it does in the first scene, and end on the product name."

Planning back from show day

If you hire it out, published estimates (as of November 2026) say to start 4–6 weeks before the show (videoeditingcompany.com), or to allow 6–8 weeks for a single video and 4 for a loop (epipheo.com). With AI you skip choosing a vendor and booking a shoot, but not review. This example is a 1-minute Standard video in 3DCG Video AI.

Before the show	What you do	Processing guide
21 days	Choose screen position, length, aspect ratio, player, and who signs off. Gather documents. Read the manual's sound rules	None
20 days	Chat, attach documents, and get the storyboard. Check numbers, part names, and claims with engineering and legal	A few minutes
14 days	Run the build and check the still images	30–60 minutes
12 days	Send your revisions together, in one or two rounds	Our sample's three runs, first build included, took about an hour
10 days	Watch the preview muted and get sign-off	Preview export
7 days	Export the 1080p final and download the MP4	About an hour
3 days	Test on the same monitor and player: looping, mute, file playback	None

This is a planning guide, not a delivery promise. Whoever approves the video sets the calendar, and builds can wait in a queue when the system is busy. High Quality takes several hours each for the build and export. Finished videos are deleted after 30 days unless you pay for keep storage, so download early if the show is further out. Inside a week, stay in Standard, cut scenes, and limit yourself to one revision round. If nobody can review it in time, don't ship it.

What it costs

Published estimates (as of November 2026) from vendors: a custom booth loop or animated explainer at $3,000–$12,000 (dmakproductions.com), and a focused trade show animation at $15,000–$30,000 (justanimations.com).

In 3DCG Video AI, a 1-minute Standard video with two small revisions is about 3,500 credits ($35), and High Quality is about 7,000–12,000 credits ($70–$120) per minute. Our 1-minute Standard sample used about 3,300 credits. We have no 30-second measurement yet. The $40 pack covers about one 1-minute Standard video, and credits don't expire, so leftovers carry to the next show (pricing). Quality limits and included work differ, so these are not like-for-like prices.

When this is the wrong tool

• You need a photoreal hero film, 4K, or an LED wall with a custom aspect ratio. Output is 1080p at 16:9, 9:16, or 1:1.
• A live demo or a presenter is the draw (compare live action and 3D). We have no avatars or presenters.
• You want a team proposing concepts, or a guaranteed delivery date. There is no human producer.
• Your purchasing requires an NDA or invoicing.

You don't need 3D or editing skills to use it. For the broader use case, see 3D animation for trade shows and sales meetings.

Frequently asked questions

Should I drop the narration if the screen will be muted?

Keep it and mute at the show. Video length and captions are built from the narration script, and the same file can run with sound at a meeting table.

Can I make a vertical version for a tower display?

Yes, at 9:16. A caption line holds about half as many characters as at 16:9, so ask for shorter sentences. We don't have a vertical sample yet, so check the still images closely.

Can I reuse the video at the next show?

Yes, within the terms of service. Keep your downloaded MP4 or pay for keep storage. If a spec changes, attach the new document and run it again, which uses credits.
