Try LTX 2.3 Pro: Audio to Video in the Workbench Run this model interactively, tune parameters, and compare outputs.
Model ID: ltx-2-3-pro-audio-to-videoHigh-fidelity audio-to-video generation from Lightricks LTX-2.3 Pro. Creates video from an input image and audio file, synchronizing visuals with the audio. Supports 1080p output at up to 50 FPS.
Example request Use the Workbench as a request builder: configure parameters for this model in the UI, then open the API tab to copy the exact cURL or Python call. Sync
Async
Async with SSE
This blocks until the video is ready (typically 5-15 minutes). Prefer Async or Async with SSE for anything beyond quick experimentation.
