Recording settings
Choose realistic resolution, frame rate, bitrate and segment duration.

Defaults are 1080p requested resolution, 30 FPS, 4 Mbps video, 128 kbps audio and 30-minute segments. Settings are frozen during a recording so the encoder and file lifecycle remain consistent.
How to use it
- For narrated slides, try 720p or 1080p at 15–30 FPS. Fast motion may need 30–60 FPS and more video bitrate.
- Select audio bitrate based on the source; higher bitrate is not a substitute for a good microphone.
- Read the hourly disk estimate, then record a short sample. Choose a shorter segment if limiting possible loss is more important than minimizing gaps.
Limits and safety
The estimate is bitrate × time ÷ 8 and excludes variable bitrate and container overhead. Requested resolution, FPS and bitrates may differ from actual browser output. Changing settings does not upscale the original screen source.
