Long shots
How long a shot can be in one run depends on whether lips must follow the sound.

Swap a person, and Rebuild with actors
Parts within a cut, never across one (about 9 seconds for Swap a person, up to about 7–8 seconds tested for Rebuild with actors). Swap a person: confirmed with the person greyed in the reference (6–7 s parts recast fully; without greying, only ~3 s did). Rebuild with actors: parts up to about 7–8 seconds tested; length didn’t matter (0.8–7.5 s), the shot type did.
- Split one long shot into balanced parts that overlap by one frame. Drop the duplicate when you join, and cut where a pause or a turn makes a small change look natural. Separate shots share no frame.
- In our tests the design held across parts when the pictures were strong. What jumped at the joins was the pose.
Add new footage, and Rebuild a shot
One run if it fits. On a 16 GB card with 32 GB of RAM:
| Size | Fits |
|---|---|
| 1024 × 576 | 124 frames (about 5 seconds) |
| 768 × 576 | 345 frames (about 14 seconds), one run, about 13 minutes |
| 768 × 448 (16:9) | 362 frames (about 15 seconds), one run, about 16 minutes; it uses nearly all of 32 GB of RAM |
- When it still doesn’t fit: split it into 124-frame pieces at full size, and give each later piece the previous piece’s last rendered frame as its first frame or Pictures (the frame export workflow saves it:
seamless-frame-export.json, download), or the set jumps where they meet.
The platform’s limits
Four different lengths, easy to mix up:
- The model: at least 124 frames per generation; the extra is trimmed.
- Your shot: its real frame count, never stretched.
- The clip: 5–120 s to submit to the catalog. Extension 0.64.3 and later play local edits from 1.5 s. Edits from the builder need clips of 5 s or more; 1.5 s clips play only as local packs made outside the builder.
- The player’s own lead-in: needs nothing from you.
