Local Editing Proxy Builder
Build local H.264 MP4 or supported ProRes Proxy MOV files with size limits, optional FPS/audio, dry-run plans, and before/after metadata.
What it does
Builds a local editing copy within maximum width and height, preserving display aspect ratio with even-pixel rounding. H.264 produces MP4; the optional supported ProRes Proxy encoder produces MOV. Select optional FPS and first-audio retention. The manifest records input and output codec, duration, resolution, and audio metadata.
How to use
Extract the ZIP and load SKILL.md in Claude, Hermes Agent, Codex, or Cursor. Supply a local input and new output directory. Inspect --dry-run before encoding. Audio is omitted unless --audio is supplied.
Requirements
Python 3.10+, FFmpeg, and ffprobe. H.264 requires libx264; ProRes requires prores_ks. Encoder availability is checked before creating output. No additional Python packages.
Caveats
No source or existing-output overwrite. No NLE auto-relink, ProRes-in-MP4, subtitle transfer, HDR mastering guarantee, or network access. Video duration is limited to six hours. Without --fps, source timestamps may remain variable-rate. Rounding can slightly alter aspect ratio. Failed runs may leave partial output.
