Timeline Recording lags when on Play Mode

Hello everyone,

I'm trying to record an animation I made with the new Timeline Window and export it into a webM or a MP4 video file with a Recorder Track. However, and even though I tried tweaking the seetings of the track, it seems recording the animation makes Unity much, much slower than normal. I can barely have around 10 fps when I add a Recorder Clip to my scene, but without it, the play mode runs smoothly. Do you have any idea of how to set up the Recorder Clip to avoid that ?
