First of all, I'm new here, so I'm sorry for posting my problem right away, it might seem a bit rude.

I got a problem with my gameplay videos. I use an Elgato Game Capture and I sometimes end up having choppy videos. They don't run smooth when the original video actually does. After recording I convert to mp4 and after that I edit it in Sony Vegas. I disable resample and maintain aspect ratio. Add a few filters and then render using the following:

The problem is that after rendering my video turns out to be choppy. Like the framerate is too low. I only got this with sidescroll games like Runner 2 or Joe Danger. Rochard is a 3d platofmer and that turns out to be just fine.
So I dunno but I assume other render settings could fix it. I just dunno which ones. Hope someone can help me out

Thanks guys!
