The video itself is 20 frames/second, but plays smoothly in windows movie player.
I import the video into Sony Vegas 11, and it is SUPER laggy, where my gameplay video is perfectly fine! I've already changed the preview settings, video settings, changed them all to best quality, but it is still laggy.
Laggy in preview and laggy in rendered video.
What can I do? Is it because of the low frame rate?
