# npm i -g gwmr-cli && gwmr input.mp4 -o clean.mp4

# from this repo:
npm install && npm run build
npx gwmr input.mp4 -o clean.mp4
# or: npm run cli -- input.mp4 -o clean.mp4

Options

gwmr video.mp4
gwmr video.mp4 -o clean.mp4 --alpha 1.15
gwmr video.mp4 --preset ultrafast --crf 20

Requires ffmpeg and ffprobe on PATH.
