Per Aspera: The Show

What needed solving.

Changing one sequence in a long episode should not silently alter approved footage, dialogue timing, subtitles, or sound elsewhere.

1. 01Drawings + timed edit
2. 02Compositing + bounded re-encoding
3. 03Verified episode revision

Simplified from the implementation and project notes.

How it fits together.

Production is organized into versioned sequences, edit descriptions, render scripts, and review artifacts. The opening-v11 notes record 38 drawings across 18 camera setups, using one to three held drawings per action rather than optical-flow interpolation.

Existing mouth rigs, environmental effects, and ship animation remain separate from pose selection. The episode-v10 edit replaces a bounded frame range, reuses unchanged picture segments, and verifies the reused media by hashes.

Delivery checks include complete video/audio decoding, frame count, duration, subtitle and chapter checks, encoded boundary samples, and audio-join measurements. Packet and stream hashes distinguish a picture change from an audio-only revision.

Building and checking it.

The work proceeds through selected drawings, timed edit descriptions, renders, encoded-frame review, and a preserved delivery version. Earlier versions remain available so an accepted scene does not disappear during revision.

The production notes make a useful distinction between checking media integrity and judging a performance: a successful decode or an unclipped waveform is not a listening review.
