Encode once for the platform and ship through the delivery gate

Ready now

One VideoToolbox H.264 encode profile used by every builder so the first review copy is already the deliverable, a registry of the last file each platform accepted, and a ship gate that diffs the encoder signature (Rec.709 in every SPS, CFR, no frame doubling) and refuses mismatches.

You need

Account	Why	Free or paid	Plan
ffmpeg + ffprobe	Every cut, mux, loudness pass, proxy, contact sheet and platform encode. The delivery encoder uses h264_videotoolbox on Apple Silicon.	Free	Free (Homebrew build includes VideoToolbox).
Python 3.12 + uv	Runs every pipeline script (video gates, library export, research cache, Brain export, PDF generator, MIDI tools) inside per-project virtual environments.	Free	Free.

What you bring

One video each platform already accepted from you, as the export signature to match

The steps

Register the accepted files
Preflight the profile against the reference
Encode once, inside the project, never into Downloads
Ship through the gate to a new name
After the upload, update the registry; on a rejection, diff first
When a source is already wrong, fix the master, never the export

Goes further if you have already built Install hooks and gates so your rules enforce themselves. You can build this without it.
