Swap a person in a 25-second ad: only Recast fits, $9.375 at 768p
Avatar Face Swap beta stops at about 15 s, Recast runs 5 to 30 s. A 25-second ad swap costs 25 x $0.375 = $9.375 at 768p or $14.0625 at 1080p on Sume.
A 25-second ad is too long for Sume's Avatar Face Swap beta, whose source window is about 4 to 15 seconds, but it fits H3 Max Recast, which takes 5 to 30 seconds. Recast costs 25 x $0.375 = $9.375 at 768p, or 25 x $0.5625 = $14.0625 at 1080p.
Route limits side by side
The three routes that change who is on screen have different ceilings, so check the length of your source before you pick one.
| Route | What it does | Source length | Rate |
|---|---|---|---|
| Avatar Face Swap beta | Puts a ready avatar face on a video | about 4 to 15 s | $0.184, $0.245 or $0.55 per s by quality |
| H3 Max Recast | Replaces 1 to 4 people using photos | 5 to 30 s | $0.375/s at 768p, $0.5625/s at 1080p |
| Kling 3.0 Motion Control | Copies motion onto a still | 1 to 30 s | $0.1575/s |
Face or whole person
Recast replaces the people in the source with the people in your photos, one photo for each person. The face swap beta applies an avatar face and the docs say it takes source video with usable audio and no prompts. They are not interchangeable: if the brief says to keep your presenter's face and only change who is in the shot, you want Recast with a photo of that presenter; if you want a consistent avatar identity, create an avatar and use face swap on clips short enough to fit.
Cost of getting it wrong
Sending a 25-second source to the face swap route is refused by its source-video check, so the mistake costs nothing but time. Splitting the ad into two 12.5-second pieces and face-swapping each at standard would reserve 2 x $2.76 = $5.52, cheaper than Recast, but you would then rejoin two clips and risk a visible seam. Decide first whether the identity must be an avatar or just a different person.
A quick selector
Answer three questions. Is the source longer than 15 seconds? Then use Recast. Do you need a consistent avatar identity that you can reuse? Then use face swap on shorter pieces. Do you only need the movement of the source on a different character? Then use Kling motion control, up to 30 seconds, with a still of the new character.
Cost for a 25-second brief at the three routes, where each works: Recast 768p $9.375; Kling motion control 25 x $0.1575 = $3.9375; face swap not available as one job. The routes do different things, so the lowest price is not a like-for-like answer.
Trim first if you can. Cutting 25 seconds to 20 saves 5 x $0.375 = $1.875 at 768p.
