WebM settings that matter

Quality controls VP9's constant-quality level: higher values keep more detail, lower values make smaller files. For most web video, 60–80 is the sweet spot.

Frame rate and scale are the other big levers. A 1080p hero video rarely needs more than 30 fps, and scaling a clip that is shown at half width to 50% can halve the file size again.
