OBS not showing iPhone camera in vertical orientation, keeps auto rotating

[LiteWerk]

Hi, I’ve been having trouble trying to get my iPhone to show up in vertical orientation in OBS on my macbook. I applied vertical dimension settings to a new profile and I set up a scene collection, but when I go to add my iPhone as the video source, it still shows up in landscape orientation, even when I am holding the phone vertically. It seems to automatically rotate and re-orient itself and fill the screen, no matter how I hold the phone. I do not have autolock on, and I tested it both with and without autolock, it did not respond or change either way, it continued to auto rotate. When I go to transform rotate CW 90° on the canvas, the iphone video retains the same viewpoint and does not re-orient itself that way either. It seems the problem lies in the drop down menu shown in my screenshot. When I am adding my iPhone as a video source, I am only getting the landscape ratios (1920x1080, 1280x720, etc). Is there not an option to get the opposite of those (1080x1920, 720x1280. etc) for portrait ratios? It seems most people are doing a workaround of cropping into the landscape video to fit the vertical screen, but that doesn’t work for me because it creates an intense zoom that I can’t work with and reduces picture quality, starts to get grainy for me.

I am seeking, what I thought was, intuitive functionality that when the phone is vertical, that is the view that would be reflected in OBS as well. Is there a setting that I’m supposed to turn off (or on) to stop this auto rotation? Or where could I submit a ticket to OBS development team to incorporate in future updates?

I'm having the same problem. Were you able to resolve?

No unfortunately I havent. I have had to just record vertical videos without using OBS. it seems the problem lies in OBS only offering 16:9 resolution ratios when adding a video source instead of also offering 9:16 resolution ratios, so the iPhone is orienting to vertical properly, but its forced to expand across the landscape canvas to fit the OBS dimensions, creating that extreme zoom. I hopped in the OBS discord and it seems they just expect people to work around this by cropping in tight, which is way too zoomed in and doesn't work for me. It significantly reduces the crispness of my video quality making it grainy and I don't even have the space to back up enough for what I'm shooting if I wanted to. Really disappointing because I would prefer to consistently record both my landscape and vertical videos in the same program to keep some production consistency. I hope the OBS developers can consider Including 9:16 ratio options in the near future as I'm surprised its not already offered, seems this would have been something obvious to add from early on.

This solves the problem in an incredibly simple way.
It's in Portuguese, but you can easily understand it because it's a video. You can also download the transcript and translate it. But it's very easy... it's almost ridiculous how much I suffered with this and now it's solved.

Basically, you mirror your iPhone's screen on the OBS screen and on the iPhone you leave the camera open. hahahah
