Hi ya’ll 🙂

I’ve noticed major flickering issues with the .webm output of BABYLON.VideoRecorder. From when I last checked about a year and a half ago, the same flickering issues are still there for a lot of scenes.

Here is a sample PG: [https://playground.babylonjs.com/#SYQW69#888](https://playground.babylonjs.com/#SYQW69#888)

After the GLB has loaded, run the Inspector\>Capture\>Record Video option. Record for about 2-3 seconds (doesnt matter that much). Then view the .webm file. Almost all frames have degraded rendering like this

My guess is it’s a compression issue.  
I’ve tried changing the renderChunk size and still no luck.

Apparently changing the mimeType to **‘video/webm;codecs=h264’** seems to make things a lot better

var recorder = new BABYLON.VideoRecorder(\_engine, { fps: 60, recordChunckSize: 3000000, mimeType: ‘video/webm;codecs=h264’ });
