Im working on a Mini TV show. Ive already made one episode but I noticed a problem

Jump to the 1:09 marker when I start to have scrolling text. The text seems to twitch and isnt smooth.
The video your watching I didnt right click on the key frames and choose smooth. But I made another video in which I did that but it made no difference. It still has the text twitching. Does anyone know how I can fix that or if I can fix it to make it much smoother?
Sorry if its a dumb question I just upgraded from movie maker to vegas a little over a week ago so theres still alot I probably dont know
