Video Issues

[newfuturefantasy]

My picture on OBS studio has a horizontal split about two-thirds of the way up. This is only apparent when I move quickly from side to side. I am filming myself playing the guitar, so my torso and head and guitar fill most of the screen. When I move side to side the split in the picture is clear, at about the level of my mouth.
I am using a Logitech C922, and it is notable that when I view using the Logitech Capture software that came with the camera, this issue is not a problem, the picture being clear.

Thanks for your help.

Do you think that a GPU might solve this problem? I am presently using my computer's internal Intel (R) HD Graphics. As I am not a gamer, would a cheap GPU rectify this issue as well as improve my overall video quality?

This 'split' you're seeing is likely video tearing.
A discrete GPU could fix it, but is not guaranteed.
You can try going into the Video Capture Device settings, and set 'Buffering' to 'Disabled', or 'Enabled' (which will increase camera latency) and see if either fix it.


As an aside, I've noted a sharp uptick in Video Capture Device 'tearing' issue threads within the last few months, and I believe it to be a bug in OBS causing it, though I'm told by at least one code contributor that it cannot possibly be OBS at fault. I find that hard to believe though, as OBS is the only software it appears in for the threads I've observed where program-independent testing was done. Fingers crossed this gets attention and fixed sooner than later.

The same tearing also occurs in the Streamlabs OSB, so it's not just an issue with OSB studio.
I've tried both the "Buffering" settings you suggest, and every other setting I can find, but to no avail.

SLOBS is based directly on OBS Studio, since OBS Studio is open-source.
Streamlabs just hacksaws off the front-end interface, slaps a webpage over the hole (because they are primarily a web development company), and intentionally breaks compatibility for plugins and scene file formats to try to forcibly lock newbies into using their inferior version.

You can also try a different USB port. Logitech cameras tend to have issues with some USB host controller brands, and can throw errors when plugged into USB 3.0+ ports (for their USB 2.0 devices), and sometimes vice-versa. I'd recommend snagging USBView which will show you the internal connection hierarchies and let you arrange your devices more efficiently so bandwidth-hungry stuff (like webcams and capture cards) won't be on the same host controller, if possible.

Thanks for the tip FerretBomb. The USBView application is a useful thing to have. But still, after moving the USB connections as you suggest, the problem persists.

Yep. Again, I assume it's a recent-ish OBS bug causing tearing in a number of situations. You can try going to an older version and see if the issue stops (I'd recommend pre 26.x.x to start).

Thanks, worth a try, but the same fault was still there with version 25.0.8!!

Further to my previous reply, I have downloaded OBS on my intel laptop and it works fine. Maybe it's a driver problem- my laptop uses Intel Graphics 4000 with i53320M CPU and works fine, but my older desktop uses Intel Graphics 2000 with i5 2300 CPU and gives the screen tearing.
