9:16 mode using iphone 13 max pro with OBS Studio

I want to record a 9:16 movie with OBS Studio on an Intel based iMac - macOS Sequoia 15.0

First thing I did is adjusting Canvas => Preferences => Video



Doing so, Canvas in OBS Studio is 9:16 so far...

BUT...

I can not adjust the ratio on the iphone camera anyhow from 16:9 to 9:16:



What's wrong here?

I am simply helpless...

Thank you for your time and any helpful hint.

I already restarted macOS, of course the position of the iphone is 9:16
OBS Studio Version is 30.2.3 (64 bit)

You can select one of the 16:9 options and then rotate your iphone source 90° (right click, select "Transform" > "Rotate ..")

@dev47 Thank you for that workaround... Another tipp is to use iOS third party App EpocCam on the iphone, but then I am actually running into the problem that the device EpocCam is not available in OBS Studio as it should be...


As you can see in my sceenshot in my OBS 30.2.3 on macOS Sequoia 15.0 there is no device EpocCam available in OBS device config

The advantage of using EpocCam is steering the camera options... and that change of 16:9 to 9:16 works

@informix you would need to contact EpocCam support. You can also try my app , which I would be able to help you with.

@dev47 Thank you for the hint of your app. Are you supporting this app by yourself and according to every future MacOS and iOS update?
