Shortest AI video on Sume: Wan 3.0 at 2 s, Seedance 2.5 at 4 s
Wan 3.0 takes 2-second clips on Sume; Seedance 2.5 starts at 4 s. A 2 s Wan clip at 480p is $0.125 on Sume. Duration floors across the catalog.
On Sume, wan-3.0 accepts 2 seconds, seedance-2.5 accepts 4 seconds, and Gemini Omni Flash 1.1 accepts 3. A 2-second Wan 3.0 clip at 480p costs $0.125 on Sume.
Short floors matter for loops, stingers and reaction cuts, where a 4-second minimum wastes budget.
Floors and a minimum clip
| Model | Floor | Cost at the floor, 480p | Cost at the floor, 720p |
|---|---|---|---|
| wan-3.0 | 2 s | $0.125 | $0.25 |
| seedance-2.5 | 4 s | $1.07 | $2.31 |
| gemini-omni-flash-1.1 | 3 s | $0.11 at 360p | $0.375 at 720p (list $0.10/s x 1.25 x 3) |
If you need shorter
- Generate a few seconds more and trim with the video trim tool.
- Check the models endpoint; floors can change.
- Loops are cheaper to test at 480p.
Why shorter clips help
Reaction cuts, logo stingers and seamless loops often run 2 to 3 seconds. A model with a 4-second floor pays for footage you trim away. At 720p, 2 seconds of Wan 3.0 is $0.25 while 4 seconds of Seedance 2.5 is $2.31.
Trimming is available as a separate video tool if you still need an exact length.
Edge cases
Duration must be a whole number of seconds. The Auto path is limited to 3 to 10 seconds. If you need a clip shorter than 2 seconds, generate 2 and trim.
Check supported_durations in the models endpoint for the current floor.
- Use 480p for loop tests.
- Pin the model for short clips.
- Trim after generation.

No. No video model in Sume's catalog accepts a seed, and the docs say a seed is not deterministic on all providers. Use references and first frames instead.
