E5 · Sync + mux to chord-chart video #7

Description

@ophiocus

Part of the Chord-chart video generator epic (parent #2).

Scope

Assemble the final deliverable: build a video track from the pictograph frames, sync it to the grid, and mux it over the original, untouched audio.

  • For each grid cell, place its E4 fretboard frame on the timeline on the beat (chord changes land where E1 said they do).
  • Encode the frame sequence as a video track.
  • Mux that video track with the original source audio (no re-encode / no alteration of the audio) into the output file.

Done when

The output video plays the original audio with the fretboard diagram changing in sync at each chord change, exported as a standard playable file.

Dependencies

Needs E3 (voicings) + E4 (renderer). Last epic in the chain; closing it closes the parent.
