Encoding Overload Error with OBS and Source Record - MacOS 15

Greets, Folks.

I had a heck of a time trying to find a way to post to the Source Record plugin forums, so posting here instead.

I have downloaded and installed Source Record recently, as I wish to do multicam recording, not streaming (at least, in this case). I have four 4K camera sources I'd like to record separately, and at the same time. I have two Sony ZV-1 cameras, each attached to Calming 4K devices. I also have a Insta350 Link 2 webcam, and using the Apple Studio web display to test, with each camera being a scene in OBS Studio. The video outputs are coming through fine in the software.

By the way, the main computer I'm using is an M1 Max MacBook Pro; 64GB unified memory, 24-core GPU, and about 2TB of free space.

When I set up Source Record for each video capture source, for some reason I used one of the 4K 16:9 aspect ratio settings; I tried typing the values in manually, but it would not let me for some reason. Otherwise, I did choose Apple VT hardware encoder for all four sources. I also put in an arbitrary bit-rate, not having any guidance on what vaoue should appear.

I then attempted a test recording from OBS. Two things occurred: first, only one source out of four had any recording, and during playback, the video was choppy. Second, saw a status later on the bottom left of the screen referring to "encoder overload." en

I admit that I'm a newbie at this, but I have to believe that I'm really close to getting it right. I could use some guidance to help close the gap. Many thanks for reading!

only thing you could try is use apple proRes hardware encoder/proress 422 proxy. thats only way I can record my 4k60 gameplay! HEVC/H264 Hardware encorders will overload! I event upgraded my MB from M1PRO to M4PRO, same issue!

I just came across this. I can't work out why its an issue but my 4k60 recordings either have massive encoder lag or they have no dropped frames. Its never anywhere in the middle.

I'm using an M4 mac mini.

I'm not even using the capture card and just recording my screen. If I go to x264 and software its fine. Yet the GPU isn't even very busy when doing HEVC or H264. Is there something wrong with OBS?
