Question / Help Choppy/stuttering local recording while the game is smooth

koevoetje · Jan 15, 2014

Hi all,

I just started using OBS local recording about a week ago.
The problem i have recording the game Rust (HL2: Source engine)is that the game feels smooth but the recording is choppy/stuttering.
Also I use OBS x64 with x264 preset: Veryfast (multithreated)

I tried crf= 18, 20 and quality 10.

Encoding
Use CBR: Disabled
Quality Balance: 10
Bitrate: 1000
Use custom buffer size: Enabled
Buffer size: 0

Advanced Options
Use custom x264 parameters: Enabled
Custom x264 parameters: crf=18

Hope to get some answers to get this fixed.
Appreciated.

Re: Choppy/stuttering localrecording while the game is smoot

14:14:45: Total frames encoded: 2110, total frames duplicated: 40 (1.90%)
14:14:45: Total frames rendered: 2113, number of late frames: 1 (0.05%) (it's okay for some frames to be late)

Its because you have too many duplicated frames. You're going to have to use SuperFast instead of VeryFast.

Also your CRF is probably overkill, personally I use something around 24 while running SuperFast for my local recording, and it looks great.

Get your duplicated frames percentage a lot closer to 0.00 and you should see the stuttering go away. You might also try increasing the capture framerate to 60, but this will increase the potential for duplicated frames and you will most definitely need to move to SuperFast preset if you do that.

Hi, I just noticed I am having this problem too. Here is the log file thing: Hopefully someone can help me with this. XD
