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.
