QuokkaPix Video benchmark

This is a reproducible local benchmark, not a claim that every browser or computer has the same performance. It runs the real Video surface through Playwright and records elapsed time, source/output metadata, backend and live capabilities.

Default cases

1. trim_video — timeline remux/transcode path.
2. vertical_9_16 — crop and resize.
3. compress_balanced — balanced compression.
4. transcribe_srt — optional Whisper case because it may download a model.

Run locally

node automation/video-benchmark.mjs \
  --input /absolute/path/sample.mp4 \
  --output ./artifacts/video-benchmark

# include transcription
node automation/video-benchmark.mjs --input ./sample.mp4 --output ./artifacts/video-benchmark --transcribe

The machine-readable case definition is available at /benchmarks/profile.json. Do not compare reports unless the input file, browser version, hardware, power mode and benchmark profile are recorded.

Privacy

The benchmark invokes the same local browser workflow. The input and generated media remain on the benchmark machine.
