Browser screen recordings can run larger than expected. Re-encoding at a lower bitrate, locally, brings them down to attachment-friendly sizes, and screen content tolerates compression unusually well.
Recording bitrate adapts to motion: static slides are cheap, scrolling and video playback are expensive. Compression evens out the excess.
Moderate compression: text stays crisp at surprisingly low bitrates as long as motion is limited.
