RV Dealer Listing Video: Three Clips, Music and Captions for $2.32

What does a listing video for a camper or RV cost to make with Sume? Three 5-second Wan 3.0 clips at 720p, one music bed, a one-minute timeline render and captions come to $2.32. That is 3 x $0.63 for the clips, $0.13 for music, $0.10 for the render and $0.20 for captions.

The catch is honesty: a listing video must show the real unit. So the plan uses your own photos as references and treats generation as camera movement, not as a substitute for the vehicle.

Shot list: exterior, living area, kitchen

Pick three photos that a buyer cares about: the exterior at three-quarter angle, the main living space and the kitchen or bath. Use each as a reference for its own clip through Video Generation, with a prompt that describes only a slow camera glide through the space.

Wan 3.0 accepts up to 10 reference images and clips of 2 to 30 seconds. The golden test prices 5 seconds at 720p at 63 cents. Do not ask for features the unit lacks; a generated slide-out that the vehicle does not have is a misrepresentation.

The full bill

Music comes from the Music Router at $0.13. Timeline 1.0 renders at $0.10 per output minute, rounded up, so a 15-second film still costs $0.10. Its plan step is free, and media must be media.sume.com artifacts, which you get by importing the clips through the media-imports route. Video captions add $0.20 for clips up to 60 seconds.

The arithmetic: 3 x 63 cents is $1.89, plus $0.13 is $2.02, plus $0.10 is $2.12, plus $0.20 is $2.32. Those are the rounded-to-the-cent prices from the golden tests; the clips' exact amounts are $0.625 each, so the true total can land a cent or two lower.

Captions that carry the sale

Captions should state facts a buyer filters on: year, length, sleeps, mileage, price. Put the numbers on screen in plain words and verify each against the spec sheet. Captions are the one place where a typo costs a sale or a dispute.

If you list several units, repeat the same recipe. Ten units cost $23.20 at this price, so the cost is steady and the real effort goes into choosing the three right photos for each.

Check before posting

Watch each clip against the photo it came from. Walls, windows and cabinetry should match; if a bunk appears where none exists, regenerate with a calmer prompt or shorter duration. A 480p draft is cheaper to test, since the provider list price for Wan is $0.05 per second there before Sume's 1.25 factor.

Include a line on the listing that the video is a generated walkthrough based on photographs, and link the original photos. Buyers of a large purchase appreciate being told, and it protects the dealer.

A repeatable workflow for a lot full of units

Treat each unit as a folder: three photos, a one-line caption sheet and a stock number. A small script can submit the three clips, wait for each to finish, import the results and call the timeline plan. Because the plan is free, you can check the order of shots before any render is billed.

Have a salesperson review every finished video next to the real unit. They know which details matter to a buyer, for instance whether the sofa converts to a bed, and they will spot a claim the model got wrong faster than any filter.

Keep the originals. If a manufacturer updates the layout or the unit is sold, you will want to regenerate or retire the clip with the exact photos it came from.

Price the benefit against the effort: at $2.32 a unit, a lot of 30 vehicles costs $69.60 to cover. The time goes into photography and review, not into the render queue.
