Car dealer year-end event: 20 walkaround clips with prices, $4.80

A dealership can prepare 20 walkaround clips with a price card for $4.80 on Sume: $0.24 per vehicle, made of a trim ($0.02), caption burn ($0.20) and a compose job that stacks your price card over the clip ($0.02) (read 2026-10-03). The order matters, and it makes price changes nearly free.

Year-end sales events run through December, and prices move during them. If the price is baked into a video along with captions and a voice, every change means a full re-render. Keeping the price card as a separate last step turns a price change into a $0.02 compose job.

Order of operations

First trim the walkaround to the 20 to 40 seconds you want. Second, burn captions for the salesperson's speech: the caption job needs audible speech and fails with caption_no_speech on a silent clip, in which case pass your own cues instead. Third, compose: operation: stack, your price card as the still, the captioned clip as the video, and an output of 720 by 1280.

Compose output length always follows the video layer, and the still is held for the entire clip. Both URLs must be media.sume.com assets, so import the card as an image and the clip as video before you start. The card is a still image you design from your inventory system, so the price, stock number and APR disclosure text come from your data, not from an image model.

Advertising rules still apply

A price on screen is an advertised price. Rules on what must be disclosed, such as fees, financing terms, and the period an offer runs, vary by state and country, so have your compliance contact approve the card template once. Put the end date of the event on the card, and recompose or take down clips when it passes.

Do not edit the vehicle. Background removal or replacement on a car photo can hide damage or change the color, and the car in the video should be the car on the lot. The same stacking technique, applied to a sale banner, is described in the price-card compose post.

Budget and checks before you start

Keep a short log with stock number, clip, price card and the date each was composed. When the event ends or a vehicle sells, you know which clip to unpublish. The compose step is cheap enough that it is better to remake the card than to leave a stale price online.

Film every walkaround the same way: front, driver side, interior, rear, and a spoken summary of the key features. Consistent structure makes the captions read the same across the lot, and the salesperson's speech carries the information while the card carries the price. A noisy lot can make speech hard to caption, so record in a quiet corner or near the showroom.
