# ffmpeg Operations Operational expertise for ffmpeg/ffprobe: the ~30 commands that cover most real work, the footguns that silently ruin output, EDL-driven editing (edit-as-code), and eight scripts that replace the logic an agent would otherwise re-derive every task. ## Doctrine: probe first **Never transcode, cut, or filter blind.** Every media task starts by probing the input — codec, duration, frame rate (constant or variable?), pixel format, rotation, stream layout. Half of all "ffmpeg did something weird" reports are a property of the *input* the command never checked. ```bash python skills/ffmpeg-ops/scripts/probe-media.py input.mp4 # human summary python skills/ffmpeg-ops/scripts/probe-media.py --doctor input.mp4 # TRIAGE: hazards + exact fixes python skills/ffmpeg-ops/scripts/probe-media.py --json input.mp4 | jq '.data.streams' python skills/ffmpeg-ops/scripts/probe-media.py --keyframes-near 92.5 input.mp4 ``` `--doctor` makes the doctrine self-enforcing: VFR, HDR transfer, rotation metadata, interlacing, non-yuv420p delivery, and moov-at-EOF each come back as a finding **with the exact fix command**, and exit 10 means "fix before processing". The `--keyframes-near` form answers "can I stream-copy a cut at 92.5s?" — it reports the nearest keyframes so you know whether a copy cut will snap (see Footguns). When a command fails with a cryptic message, decode it: [references/error-decoder.md](references/error-decoder.md). **Before recommending an encod...
