Try LTX 2.3 Pro: Retake in the Workbench Run this model interactively, tune parameters, and compare outputs.
Model ID: ltx-2-3-pro-retakeTargeted video editing from Lightricks LTX-2.3 Pro. Regenerates specific segments of existing videos (2+ seconds) while preserving motion continuity, lighting, and surrounding footage. Supports replace video only, replace audio only, or replace both with natural language prompts. 1080p output.
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.
