I use screen recorders all the time. Question: what format does it capture in? Some screen recorders capture as mov files, which get janky in high zoom. A pro app like Camtasia captures in what I assume is the raw screen data, and for this reason zooming in on a clip works really well.

I use getDisplayMedia which is a JavaScript API that lets you capture recordings as large as your computer can handle, but the format is fixed to either MP4 or WebM. Here is the JS-based player: https://screenrecorder.me/projects/s3hx9YRgXNsrN1s/player https://screenrecorder.me/projects/s3hx9YRgXNsrN1s/player Here is a video that I rendered: https://screenrecorder.me/player/s3hx9YRgXNsrN1s https://screenrecorder.me/player/s3hx9YRgXNsrN1s There are definitely artifacts, especially in the latter, but in practice the videos I've been creating have been working well. Also, it's primarily because the zoom is so high. In practice, I usually set the zoom much lower and it doesn't have as much artifacting.

  Would it also capture system audio? Wasn’t there some security restrictions on that for MacOS

    Audio capture support apparently available on all desktop browsers except Firefox: https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getDisplayMedia#browser_compatibility https://developer.mozilla.org/en-US/docs/Web/API/MediaDevice...

      System audio (i.e. Zoom calls) can be captured only on Chromium browsers on Windows and ChromeOS when sharing the entire screen; tab audio has wider OS support; Safari and Firefox do not support system or tab audio capture https://addpipe.com/docs/recording-client/screen-recording/#feature-support https://addpipe.com/docs/recording-client/screen-recording/#... The MDN support table does not differentiate in this regard. (le: it actually does if you click to see the implementation notes)
