Question / Help Encoding with x264 results in EXTREMELY choppy footage

Using the Nvidia encoder I get really smooth video, but when i encode with x264 it drops to less than 15fps (just a guess).
I believe I need to encode with x264 to produce videos that are compatible with Sony Vegas (this is an assumption since normally my videos dont work in Vegas - I need to convert them using software to x264 in order for it to load into vegas)
How do i fix this FPS issue?

The nvidia encoder produces the same video format as x264. The format, called h.264, is standardized. You should be able to open any h.264-encoded video in every h.264-enabled video editor including Sony Vegas. If this isn't the case, it is either a bug (either in OBS or in Sony Vegas), or you did change something else in addition to changing the encoder.

This should work:
  • record with nvenc and use *.mkv as container format
  • remux (convert) the *.mkv file into *.mp4 file by using OBS File->Remux Recordings
Remuxing doesn't re-encode the video. It just converts from the *.mkv container format to the *.mp4 container format. It's as if you take a cardboard box, unwrap its contents and repackaging the contents into a new cardboard box that has a slightly different color and dimensions.

Also, if you want to use x264 to encode over NVENC for some reason, you could try the ultrafast preset. That usually fixes most lag issues.
