Five CLIs around DaVinci Resolve music-video editing, all inference local on Apple Silicon (MPS/MLX): - vg-roto: SAM 2.1 + MatAnyone click-to-cutout -> ProRes 4444 alpha - vg-index / vg-find: PySceneDetect + mlx-whisper searchable clip library - vg-beats: librosa beat grid -> Resolve marker EDL - vg-transcode: legacy codecs -> ProRes LT, deinterlaced, resumable setup/setup_venvs.sh rebuilds venvs, tool clones, checkpoints and applies patches/matanyone-cv2-reader.patch (torchvision >= 0.23 removed read_video). Verified end-to-end on ultra 2026-08-24; setup/smoke_test.sh covers the lanes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# vg-transcode — batch-normalize old footage to ProRes LT for editing.

|
# Usage: vg-transcode SRC_DIR [DEST_DIR] [--h264]
|
|
# Recurses SRC_DIR, converts every video to ProRes LT .mov (or H.264 with --h264),
|
|
# mirrors the directory structure, skips files already done, deinterlaces
|
|
# interlaced sources (bwdif to progressive at double rate).

# Heartbeat: ~/.jobs/vidgod-transcode.status
