summary

Claims a practical replacement for duplicate compositor work by running the editor inside a browser pipeline using Puppeteer + MP4Box.js + WebCodecs + canvas + ffmpeg. The pipeline demuxes, decodes to frames, draws with canvas (including GIF-as-frames compositing), re-encodes to raw H264 frames and hands those to ffmpeg for final muxing. An earlier screenshot approach proves too slow; workarounds address headless GPU codec limits. Prototype runs with the experimental flag and produces real exports that match the preview.
