Question / Help Recording WoT game replay: Video doesn't move, sound is OK

[Hugo Baskerville]

Hello,

I have a problem with recording replays from World of tanks game. I can't force OBS to record it propertly. When I start recording it capture only first frame and then only sound goes right.

I was trying capture monitor, game or window and switch between full screen and windowed game client also, it is not working and I wasn't able to find suitable answer, please help.

Thanks
Hugo Baskerville

First, your CPU is really old to be doing x264 encoding. 80 to 90% duplicated frames makes me doubt it'll ever work even if we tweak all your settings perfectly. That said...
Try using Game Capture, not Windows Capture, its faster.
Use UltraFast preset instead of Very Fast
Try using a downscale if the above doesn't drastically reduce your duplicated frames.
Try encoding at 20fps instead of 30fps.
Try setting your buffer size to 0.

Try these and post a new log file from a 5 minute or longer attempt. It seems likely though that you just need a stronger computer.

It works!

Used game capture, ultra fast and buffer size to 0. Didnt used downscale

When I switch from 30 to 20 FPS it runs better, but anyway 30 FPS is stil usable with little decreasing of image quality.

Thank You a lot, there is a log file of my last attempts.

That's good, I had my doubts. I think Game Capture was the important part.
