M1 Video Effect (Portrait Mode) in OBS

Hey Everyone,

I've been using the m1 Portrait mode effect (a native effect in OSX) which gives you dynamic background blur to web cameras. This works well in OBS so long as you only have 1 "Video Capture Device" (eg the webcam). But as soon as you have at least 2 Video Capture Devices (a webcam + a video capture card from a console) the Blur stops working and the CPU gets pretty much pegged. Window Captures and Screen Captures don't seem to count for the Portrait effect interestingly enough.

Does anyone know if its possible to apply the Portrait Effect to a single Video Capture Device in OBS? Alternatively if there was another way to apply the effect to webcam that you know of would be helpful (StreamFX while good doesn't seem to apply the dynamic realtime filter that portrait mode does).

Its pretty hard to google how the Portrait Effect works at all, so I'm sorry if this was already answered.

Bump!

I have the same question. M1 Mac Studio here. I see the effect working in the Logi Tune control panel (up to date). It also works in Quicktime when recording a video.

I'm on MacOS 12.6.1 - I know it's not the most recent but I don't want to update with projects unfinished in FCP and elsewhere.

EDIT: Only workaround I think is to keep Logi Tune open and use another OBS display or app input capture and grab the Logi Tune preview. I don't like having another thing open and OBS having to do even more work but, that's all I can think of currently.
