Inspect subtitle and frame outputs with execution records, deliver a short film from a complete package, and distinguish demos from reproducible evidence.
Run an original 3.6-second caption exercise with a licensed pinned Noto CJK font, a dependency-free cmap checker, real FFmpeg/libass rendering, four decoded frames and 29 executed checks. Separate missing-glyph checks from readable, regionally correct text.
A runnable Python and FFmpeg frame-extraction recipe with original CFR/VFR fixtures, rational PTS tables, three selection rules, PNG pixel hashes and 16 executed checks.
Inspect two MiniMax H3 source demos, an original practice and a local execution fixture to separate displayed clips, input completeness, interface tests and model-effect evidence.
Prepare three products separately, review each shot, then hand off exact copy through an editing layer. Includes original fictional product art, shot data, reproducible FFmpeg assembly, an actual local MP4 and execution receipt.
