Buffer duration & codec support limits
Operational constraints and validation boundaries: Requires a secure browser context and native display capture and recording support. Shared audio is included only when the browser supplies it. When multiple audio input tracks are present, they are mixed into one track at equally reduced levels; a single input retains its level. Camera mode uses a bottom-right inset and scales the shared image to at most 1280×720, requesting 30 fps; keep this tab visible while recording. Without a camera inset, resolution and frame rate depend on the shared source. MP4 is offered only when the browser reports native support; this tool does not convert WebM to MP4. Recording may still fail if resources or codecs are unavailable. Keep recordings under 60 minutes; recordings stay in memory until downloaded, and long sessions can exhaust memory.
