Try LTX-2 Retake in the Workbench Run this model interactively, tune parameters, and compare outputs.
Model ID: lightricks-ltx-2-retakeLTX-2 Retake is a Multimodal LLM designed for targeted video editing. It excels in regenerating specific segments of existing videos (2-16 seconds) while preserving motion continuity, lighting, timing, and surrounding footage, enabling efficient revisions without full clip regeneration.Some other noteworthy features of LTX-2 Retake include replace video only, replace audio only (e.g., dialogue or ambience), or replace both with natural language prompts; support for up to 20-second input clips at 1080p output; and seamless integration into iterative production workflows.
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 with SSE
This blocks until the video is ready (typically 5-15 minutes). Prefer Async or Async with SSE for anything beyond quick experimentation.
