Animate to video

An image-to-video workflow turns a still into motion. Pass the source image and a video workflow ID to POST /api/video/generate.

Name an action, not an atmosphere — an image-to-video model animates the pose in the start frame, so the clip should show an event someone could describe afterwards. Words like “slowly” and “gently” produce a near-still clip.

Run one action longer

An image-to-video clip runs about five seconds. For a single continuous action past that, use the wan22_i2v_context workflow and set length — it samples the whole clip in overlapping windows instead of generating separate takes, so the action carries through rather than restarting.

Chain into the next shot

Chaining is for a new shot — a different action, angle or place — not for making one action run longer, because each chained clip starts the model from a still.

POST /api/video/last-frame returns the final frame of a finished video as an image filename, which you pass as the image of the next shot, so the new shot starts on the frame the last one ended on. Name the clip by the prompt_id that made it, or by filename. The frame is cataloged like any upload, so you can edit it before animating it when the next shot needs a change motion alone can’t make.

POST /api/video/stitch joins finished clips into one video in playing order. Each is matched to the first clip’s frame size and frame rate, so shots that differ still join cleanly.

Give it a voice

POST /api/tts/generate speaks a line with ElevenLabs and returns an audio file. Pass that file as the audio of an InfiniteTalk video job and the person in the shot speaks it, lip-synced.

curl -X POST <your-api-url>/api/tts/generate \
  -H 'Content-Type: application/json' \
  -d '{"text": "You were supposed to wait for my signal."}'

Name a character to use the voice stored on it, or a voice_id from GET /api/tts/voices to pick one directly. This needs ELEVENLABS_API_KEY in your environment; without it the endpoint returns 503 and the rest of the API is unaffected.

Voice belongs at this stage rather than at final assembly: audio laid over a finished clip does not move the mouth.
