Hugo has no video processing, so FFmpeg runs in the builder stage
before hugo builds, compressing every content/**/*.mp4 in-place.
scripts/compress-videos.sh:
- H.264 CRF 28 + preset slow (good web compression)
- faststart for progressive streaming
- AAC 64k audio
- Only replaces source if output is actually smaller, so
already-lean videos are skipped
Dockerfile:
- apk adds ffmpeg alongside hugo in the builder stage
- RUN compress-videos.sh runs after COPY . . before pnpm build
(compressed files land in public/ via Hugo's copy of page bundles)
