AV1 being REALLY unstable on vegas timeline.

ThenonFun wrote on 5/22/2025, 2:51 AM

Hey all!

So i record all my videos on quicksync AV1, i own and use an intel arc a750 after all.

However, using vegas 22 with ANY video that happens to be av1, makes the program 100% unuseable. It crashes so often, do a splice? Crash. Move through the timeline too fast? Crash. Save? Crash. Its super unstable, and this doesnt happen with any other codec.

It might be my ram, thats been really unstable as of late, but i dont feel like the ram would cause so many freezes and straight crashes. Is this a problem with my ram, or is it just intel arc drivers not correctly working with vegas?

SYSTEM SPECS

12400f

A750

16 gigs of ram

One 512 gb m.2 ssd and one 200 gb sata ssd.

Thanks,

Jussi.K

Special reason for screenrecording gameplay with AV1? I think there're more suitable and easier editable codecs for that purpose.

I am not seeing issues with a rendered AV1 file playing back on Vegas 22 timeline. Maybe if you upload a clip we could try it out.

I do it becouse for some MAGIcal reason, every other codec lowers my fps in games alot, and causes stutters. Even running a game like hl2 while recording in something else makes the game way harder to play

@ThenonFun Can you share your exact settings? Are you setting the keyframe interval to 1 in OBS?

What does "show problem details" in the error report say when you click on it?
