  You need to provide more info so the community can help you.

  • Specs on your computer, CPU, RAM, GPU…
  • utility being used to capture game footage, and format you are capturing to.
  • “media info” on the captured media.
  • Project settings in Vegas.
  • Desired rendered output / Vegas Render As template
  • Preferences settings in Vegas.

  Seriously this request should be a sticky on the forum to guide people on how to post for help.

  Under OBS -> Settings -> Advanced – is the CFR (constant frame rate) checked?

  Download a copy of “Media Info” and verify the OBS encoded media is being encoded to a constant frame rate of 60 or 59.94 FPS.

  Try the results of using the x264 encoder vs using quicksync or NVENC.

  Try disabling smart resampling for media clips on the timeline.

  Try Xsplit Broadcaster, as OBS fails to encode to a “video standard” Below is a media info output on an xsplit file:

  Video
  ID : 2
  Format : AVC
  Format/Info : Advanced Video Codec
  Format profile : Baseline@L3.1
  Format settings, CABAC : No
  Format settings, ReFrames : 1 frame
  Codec ID : avc1
  Codec ID/Info : Advanced Video Coding
  Duration : 23s 12ms
  Duration_FirstFrame : -21ms
  Bit rate : 113 Kbps
  Width : 1 280 pixels
  Height : 720 pixels
  Display aspect ratio : 16:9
  Frame rate mode : Constant
  Frame rate : 30.000 fps

  Vegas is a Video editor that likes encoded source material that conforms to video standards in the TV and Film industries. The video standard in your use case would be 1920x1080x59.94P FPS, or 3840x2160x59.94P FPS. A straight 60FPS should work too, but Media Info results similar to 58.465 to 60.366 will cause playback issues in Vegas.
