How To Export Svg Animated With Javascript To Movie Format?

I've been making animations with a library called SVG.js, this library uses javascript and requestAnimationFrame to animate SVG elements instead of the supplied SMIL

Solution 1:

You can always record your screen with eg. OBS playing your SVG in the browser (or whatever you use to play it) and :

1. Get OBS from https://obsproject.com/, install it, run and learn how to record your screen. It's easy as hitting the "start recording button" on the right bottom of the app window.
2. Open your SVG in your preferred browser or player you use. If possible, make it full screen. Make sure you can restart animation easily - like using CTRL+R to refresh the browser window.
3. Switch to OBS and start recording (on Mac OS you can start it from the menu bar).
4. Switch to browser or player and replay your SVG animation. Wait for a second after it stops, to have enough gap for editing later.
5. Switch back to OBS and stop recording. Video is saved as MP4 - check the quality, if not enough, change OBS settings and try again.
