EOS RP with OBS Studio has Vertical Black bars

[sderworiz]

Hi there,

I have an EOS RP connect to my PC in Windows 11.

I use OBS Studio.

My camera source has two vertical black bars on either side of my camera. However when I deactivate and activate the source it briefly goes full but then immediately sizes down with the two black bars. I have no out of the ordinary filters or anything set that would cause this in OBS.

Hi sderworiz,

To trouble shoot this we would need to know what type of cable you are using to get the video feed from the camera.

Is the EOS RP in stills mode or movie mode. I think you will need to use Movie mode since stills is 3x2 aspect ration and movies is 16x9 ratio. OBS usually expects 16x9 and would allow 1920 x 1080 pixels, but if the camera is sending 3x2 ratio - due to be in stills mode - then this would be shown as 1620 x 1080, so a 150 pixel wide black bar at each end.

This was it!  I put it into Movie mode and no more black bars. However OBS can only see it at 720p, is that normal? No option for 1080p, or is there a setting in camera I need to change?

thanks again!

Have you set tbe camwea to create clean HDMi as they should mean 1920 x 1080 output?

Just found the setting, put it to HDMI AUTO and to 1080p

However I am connected to my PC via USBC to USBA 3.0 cable. Do you know if this will support the 1080p or higher resolution? 

I don't have the Elgato camlink so I can't connect HDMI to the PC unfortunately, that's why I am using the USBC cable.

thx!

Are you using the EOS Webcam Utility software to communicate with the camera over the USB cable, then feeding the output of the webcam utility in to OBS?

[sderworiz]

Yes exactly. Connect usb cable from eos RP to Desktop, launch capture device source in OBS. Movie mode on camera is set, although it feels like 30fps instead of 60fps. The OBS source shows 720p/30fps as my only option.
