30 seconds of ad video: Omni $3.85, Kling 3 $6.40, Seedance 480p $8.10
Thirty seconds on Sume at list: Omni 720p in three clips plus a render $3.85, Kling 3 with sound $6.40, Seedance 2.5 at 480p $8.10 in one job.
Thirty seconds of video costs $3.85 on Gemini Omni Flash at 720p (three 10-second clips plus a $0.10 render), $6.40 on Kling 3 with sound (two 15-second clips plus the render), and $8.10 on Seedance 2.5 at 480p (one 30-second job, no join needed). Wan 3.0 at 720p is $3.75 in one job and $3.85 with the render.
The cheapest route here needs a Timeline join only for Omni and Kling. Seedance and Wan do 30 seconds in one request, so a render is optional.
The table
Rates are per second on Sume: Omni 720p $0.125, Wan 3.0 720p $0.125, Kling 3 $0.14 silent or $0.21 with sound, and Seedance 2.5 about $0.27 at 480p 9:16.
The Timeline fee is $0.10 per output minute, so a 30-second join costs $0.10.
| Route | Jobs | Clip cost | Join | Total |
|---|---|---|---|---|
| Omni 720p | 3 | $3.75 | $0.10 | $3.85 |
| Wan 3.0 720p | 1 | $3.75 | none | $3.75 |
| Kling 3 silent | 2 | $4.20 | $0.10 | $4.30 |
| Kling 3 sound | 2 | $6.30 | $0.10 | $6.40 |
| Seedance 2.5 480p | 1 | $8.10 | none | $8.10 |
Why the cheap one is not always the pick
One job gives one continuous take, with no cut points. Three Omni clips give three takes you can replace one at a time. Resolution differs too: 480p is a draft tier.
Seedance 2.5 also accepts audio and video references, which Omni does not.
