Why one take matters
The other 11 of the 15 video models in Kreavo's price index stop at 20 seconds or less. A 30-second ad made on them is two or more clips joined together, and each join is a place where the face can shift, the voice can change tone, the light or the background can jump and the product can move in the hand.
A clip made in one generation has no join: the whole clip comes from the same render, from the first second to the last, so there is no cut to hide.
- Use a photo of your AI influencer as the first frame, so the face is the one you chose, not a random one.
- Keep the script to what fits in 30 seconds of natural speech. A shorter script sounds less rushed.
- Watch the whole clip with sound before you publish it, not just the first seconds.
To keep the same person across several ads, not just within one, reuse the same influencer photo every time. More on that: how to keep the same AI influencer face
How long a 30-second take takes
Seedance 2.5: the median was about 5 minutes (301 seconds) from request to finished video, over the 8 customer clips of 20 to 30 seconds completed in the last 120 days (measured November 9, 2026). Across all lengths, Seedance 2.5 takes about 4 minutes (median of 174 completed jobs over the last 60 days, all lengths and resolutions together, from request to finished video). Grok Imagine, Wan 3.0 and Kling 4.0: not enough customer clips of 20 seconds or more yet to publish a median. We will add them once there are.
When 15 seconds is the better buy
Prices are per second, so a 15-second clip costs about half:
| Model | 15 s at 720p | 30 s at 720p |
|---|---|---|
| Grok Imagine | $1.38 | $2.75 |
| Wan 3.0 | $3.00 | $6.00 |
| Kling 4.0 | $3.75 | $7.50 |
| Seedance 2.5 | $6.75 | $13.50 |
Test hooks at 15 seconds: whether the first two seconds hold attention does not depend on the length of the rest. Pay for the 30-second take once a hook wins and the ad needs a full demo or story.
