Looking at the log, its a lot better, but its not fixed. You can see in the log there is slight loss:
16:55:09.755: Output 'simple_file_output': Number of lagged frames due to rendering lag/stalls: 562 (1.3%)
16:55:09.761: Video stopped, number of skipped frames due to encoding lag: 127/42602 (0.3%)
This means your setup is struggling with the current settings we have used in rendering (GPU) and encoding (CPU). It can be weak hardware or just wrong settings. Of course, the more powerful CPU/GPU combination you have, the better results you can obtain. Looking at your computer hardware, you should be able to do 720p recordings just fine but 1080p maybe a struggle.
I would suggest doing the following in the order below to try to improve the situation:
- Disable any applications you don' t need running that are started up when booted. Look in Task Manager | Startup tab
- Download CCleaner or Glary Utilities and clean up your computer
- Don't run applications you don't need that are sucking up CPU while you recording
- Lower your application/game video settings one level down for the features you can tweak (i.e. Ultra to Medium for antialiasing, etc.)
- Set the Recording Quality one level down to High Quality, Medium File Size if you need to
MKV is preferred over MP4 because if all of a sudden your recording stops like the power is lost, your computer crashes, etc. you will be able to retain everything you recorded up to the time it crashed. YouTube ingests MKV file format but if you want to target MP4, you can use something called
Handbrake to convert the recorded MKV file to an MP4 file. Its free too.
