Lightricks LTX 2.3 Retake Video

Retake a selected segment in an existing video using prompt-driven edits.

Model Overview

LTX 2.3 Retake Video regenerates a targeted segment inside an existing clip. You can replace audio, video, or both over a selected time window while preserving the rest of the source.

Best At

• Targeted segment edits without rebuilding the full clip.
• Prompt-guided shot or action adjustments in short ranges.
• Rapid revision workflows for creative feedback cycles.

Limitations / Not Good At

• Works best on short, clearly defined retake windows.
• Large semantic changes can reduce continuity with surrounding frames.
• Precision edits still depend on source quality and prompt specificity.

Ideal Use Cases

• Fix or restyle a specific shot segment.
• Replace only audio, only visuals, or both for a range.
• Fast revision passes before manual post-production.

Input & Output Format

• Input: required prompt and video_url; optional retake_mode, start_time, and duration.
• Output: retaken video URI returned on response.

Performance Notes

• Clear start_time and duration windows improve consistency.
• Use focused prompts for shot-level edits rather than global rewrites.
• retake_mode controls whether audio, video, or both are replaced.
