Hey everyone,
When recording gameplay footage using OBS (1920x1080, 60fps), I can see in the OBS interface that it is recording at 60fps, with zero frames dropped (bottom right corner of interface). However, after the video is finished being produced, I play it back in VLC and it is not at a smooth 60fps. It looks like at some points it stutters, when in-game there were no stuttering issues at all. To try and be a little more informative, for a game like Rogue Legacy, it seems like every 3 seconds it will drop frames (on a consistent basis) during video playback, and for a game like Shadow of Mordor it kind of takes the same approach except just less smooth overall. Edit: From what I can see, it looks like it stutters in the preview window as well, yet still says 60fps in the bottom right. Game is running at a smooth 60fps, however looks like some problems with the actual recording process.
To do a comparison, I recorded from a different program (Action! by Mirillis) and was able to achieve smooth 60fps footage (for both games above) with no stutters whatsoever in video playback. I love the customization and features of OBS, so I really want to make this work. There has to be a reason why it would be stuttering in video playback, especially when another program seems to work fine. My specs/some settings are as follows:
Specs:
i7 4790k
GTX 970
16gb DDR3 RAM
750w PS
Settings:
Game Capture (capturing Steam game)
x264 encoder
CBR and CBR Padding Enabled
15000 kbps bitrate
veryfast and normal priority
Here is my log file:
I will eventually want to start streaming (which I heard OBS is the best for), but I'm afraid I will still run into these stuttering issues during viewer playback.
Thank you so much in advance for the help, and if you have any further questions please let me know!
