Why does it jolt?

Here is my issue. I record game-play with XSplit Broadcaster. I use Sony Vegas pro 13 or 14 to edit videos. Now I watch the videos, to make sure everything was recorded right and to pick what to keep and what not to keep, before I import them into Vegas. Once i finally made up my mind and I have the Video in Vegas.... The game play in the preview is going back and forth the last frames when there is movement in the game-play... The video keeps going like normal, but the weird jolting back and forth stays. Audio is fine, the length of the video matches with the Audio, but the weird jolting is still there.

I render the video thinking it was just the preview being weird, when I watch the final product... The jolting is still there. You can not see movement of any source without that constant jolting.

I have Edited my Art speed-paints with Vegas, no issues, it is only with my game-play videos.

 This is the original video before Sony Vegas.

This one is after Sony Vegas.

It sounds like an issue with variable frame rates -- part of the compression system that many screen recording apps use and which can cause lots of goofiness when you're editing.

Although this tutorial references a different editing program, the principle is the same. And Handbrake is still the solution.

I have read that Xsplit Broadcaster has a constant frame rate setting. If so, you should choose that setting for editing the recordings in Vegas. Or you could try OBS Studio with these recommended settings.

I've had similar render bugs before...If the above doesn't work, make sure you have updated to the most recent version of Vegas Pro, as it fixed a lot of those bugs for me.

I tried that, it still did the same, and OBS will not work on my laptop for some odd reason.

In that case, Start Here, and post your complete MediaInfo and Vegas file properties. We know nothing about your codecs and parameters.

Personally, I do not use software to record my video screen. I just hook up a video recorder (which at this time is a Blackmagic Video Assist 4k, though I used other devices long before BVA came to exist) to the HDMI output of my computer and use that to record whatever I am working on. That way nothing is slowing down my computer, nor does anything ever crash. Plus, I get to control the frame rate of the recording, which generally does not need to be as fast as the frequency of a monitor, so I end up with a much smaller file, yet of a higher quality.

And if needed, I can even hook up a studio quality microphone to the recorder, completely bypassing the need for some software to record my narration.

I'm sure more consumer-grade computers will have HDMI output in the future. Which one are you using?

Haven’t they had HDMI outputs for many years? And before that DVI, which is easy to connect to an HDMI input with a simple passive adapter or cable. At any rate, I’m currently using the MSI GT72s 6QE Dominator Pro G laptop.

Guess I'm just behind the equipment curve.

That’s OK. 😉
