Tour Operator Trip Teaser: 30 Seconds in One Job, and Kling 4.0?

Can a tour operator make a 30-second trip teaser in one AI video job on Sume? Yes, with wan-3.0 or seedance-2.5, which both accept up to 30 seconds. Sume does not list Kling 4.0, and the kling-3 it does list keeps a 15-second cap.

That matters this week because Kling's own comparison page says 4.0 stretches the clip length to 3 to 30 seconds. A reader who sees that headline may assume the new Kling is available everywhere. On Sume, it is not.

What the Kling page says, and what Sume carries

Kling's blog post Kling 4.0 vs 3.0 (read 2026-10-10) states that 3.0 handled 3 to 15 seconds and 4.0 handles 3 to 30 seconds, with 720p, 1080p and 4K output. It also says Kling 4.0 Flash had early access for a limited group on September 28, with an official launch planned for October. It gave no API status in the text I read.

On Sume, the video catalog behind the Video Router lists kling-3, which takes text-to-video or start and end frames only, with a 4 to 15 second range. There is no Kling 4.0 entry, so a plan that depends on it would have to wait until it is listed.

A teaser plan that works today

Write the teaser as a single continuous idea: a coastline at dawn, a market, a boat, a table. A 30-second job lets one prompt carry the whole arc, so you avoid stitching six clips where the light and the colour change at each seam.

Use your own photos as references wherever the place must be real. wan-3.0 accepts up to 10 reference images, so give it the actual harbour, hotel terrace and trail you sell. A generated beach that does not exist is a complaint waiting to happen when guests arrive.

Cost of the 30 seconds

The golden test prices wan-3.0 at $0.625 for 5 seconds at 720p (shown as 63 cents). Wan's list price is $0.10 per second at 720p and Sume bills list times 1.25, so 30 seconds at 720p is 30 x $0.125 = $3.75. At 480p the list price is $0.05 per second, so the same 30 seconds is 30 x $0.0625 = $1.875, about $1.88.

Draft at 480p until the composition is right, then render the keeper at 720p. Two drafts and one final comes to $1.875 + $1.875 + $3.75 = $7.50 in total for a single teaser.

Finishing and honesty

Trim the result with Video trim for $0.02, add Video captions for $0.20 so the destination names show, and lay in music from the Music Router at $0.125.

Label the clip as a teaser, not a brochure. Travel buyers hold operators to what they see. Keep real photography beside any generated scene, and revisit the model choice when Sume lists Kling 4.0, if it ever does.

Seedance 2.5 as the alternative

seedance-2.5 also accepts clips up to 30 seconds, from 4 seconds up, at 480p, 720p and 1080p. The golden test prices a 5-second 720p clip at $2.89 (shown in cents), which is far above Wan, so reserve it for a hero shot where you want its look and have budget for it.

A sensible split for a trip page is one Wan teaser at 720p as the main film and, only if the page needs it, one short Seedance shot of the signature view. Compare them side by side on the same prompt before you commit a season's budget to either.

Finally, check each place name and each landmark in the output. A model can place a famous building beside the wrong coastline. Your guides know the route, so ask one of them to watch the teaser before it goes live.
