Question / Help dropped frames even before recording

[IrrerDrongo]

Hi, I am using OBS for recording old VHS-tapes and have problems with dropped frames. After some minutes, maybe in a scene with a lot of movement, the framerate dropes a little bit. Not huge, but visible. And it does not only happen when I record the video it even happens while I am in the OBS-Software and just watching the USB-Video-Source. I thought about the video grabber: it is a Basetech USB 2.0 Video-Grabber BR116. Its just USB 2, maybe it is to much data to be transfered via the USB. But: when I close OBS and open it again, everything is normal, like clearing a cache... is it possible to "empty the cache" or whatever is neccessary while running the software, without closing/reopening it?

My last log file.

That honestly sounds like the drivers for the capture device are dying.

Dying? Its not the best driver or what do you mean. Indeed, it was not easy to find, this driver.

It's likely either the device or the software for the device are the actual root cause of the issue, and you should look for a more high-end capture device.
