Editing AV1 footage is really intensive on ram and buggy.

Hi everyone!

Ive noticed that editing any AV1 video fills up ram alot and really fast, eventually it runs out of ram, and starts writing to the pagefile, and that causes my windows to slow down and eventually lock up. Anything i could do to fix this?

I'm not surprised as 16GB Ram is not very much.

As an example I load four AV1 4K clips giving a 4min duration. Fade each clip with 2sec fade V22 uses 10GB of RAM . Also AV1 is harder to edit than my normal Camcorder media XAVCS, you can see that navigating the timeline is slower and finding precise frames takes longer.
