AI Video · first last frame to video
Frames to Video
Frames to video is for directors who already have two compositions. Upload the opening still and the closing still, describe the path, and let the model invent the in-between — not a random ending. If either frame is a talking face, run lip sync after the motion lands. If they are landscapes, ship the bridge as B-roll.

Each model has its own length and resolution caps. Seconds and quality chips update when you switch Seedance 2.0, Seedance 2.5, Veo 3.1, or Wan 2.5. Paste a Wavespeed key on Admin → Models.

Why people use first last frame to video
You pick the destination
Text-to-video guesses the last frame. Here you supply it.
Camera path in the prompt
Push, pan, whip — say the move so the interpolation is not a morph soup.
Identity lock when both frames are the same person
Use two crops of one avatar, not two different faces, if the shot is a host.
Then speech if needed
Motion first. Mouth second. Same as the rest of the video tools.
Three simple steps
- Step 1
Upload first and last frames
Same aspect. Similar lighting helps.

Action, camera, duration.
- Step 3
Generate, then lip-sync if a face is talking
Generate, then lip-sync if a face is talking. Otherwise download the bridge.
