Hi, I use latest OBS v0.657b and I use Avermedia GL310 usb capture card and videocam. I read many instructions and manuals but cant find the answer. The situation is: When I just started OBS all is well, audio and sound sync, but after an hour and sometimes 10 minutes audio unsync, I use teamwiever for caprute presentation on another computer,It is not the case. Some people turn on, turn off capture device and it solved the problem. I try to turn on buffer but it didnt help.
I tested 2 computes with Intel core i7.


OBS LOG Anylizer

Aero is disabled

Aero seems to be disabled, consider enabling it unless using monitor capture.

Multiple video cards detected

If you are having problems and are using a laptop, see this thread for advice.

If you are using SLI or Crossfire, you may need to disable it for compatibility with OBS.

Excessive audio bitrate

Audio bitrates higher than 128kbps are rarely needed for internet streaming. Consider keeping the bitrate around 128kbps for optimal bandwidth usage.

Monitor capture detected

One of your scenes appears to be using monitor capture. Monitor capture is the slowest and least efficient method of capturing, and can cause FPS lag on both your stream and your game and will also cause problems capturing full-screen games. Consider using game capture or window capture instead (this does not apply to Windows 8).

the letest log file
Try 1ms buffer for the capture card.

Code:
20:43:03:     max bitrate: 2500
20:43:03:     buffer size: 2496

set buffer to the same as bitrate

is there a way to set your capture card to 50fps then select interlacing? not sure if this would work.

Buffer 1ms doesnt help and bitrate too

I tried to change fps in OBS but only became worse
no, the capture card's frame rate. can you set it to 50 interlaced?

EDIT: can you also check to see if you can run a different frame rate on your camera? maybe 30p and base all your setting on that?
