Slice Video Frames

Use the bundled scripts for deterministic extraction and optional chroma-key cleanup. Do not add generation, sprite-sheet packing, motion evaluation, or engine-specific packaging to this skill.

Workflow

1. Inspect the source clip and confirm the usable time range.
2. Choose one sampling mode:
   • --fps RATE for evenly timed playback frames;
   • --count N for exactly N representative frames across a range;
   • --timestamps LIST for hand-selected source times;
   • --every-frame for every decoded source frame.
3. Extract into a new output directory. Keep the default PNG format when quality or alpha matters.
4. Use --remove-background only for a deliberately flat, solid chroma-key background.
5. Verify frame count, ordering, dimensions, timing, and alpha before returning the output paths and manifest.

Require the user to choose a sampling mode when intent does not imply one. Avoid --every-frame for long clips unless the user explicitly needs all source frames.
