oh never mind, I think I found the answer:
"Try recording from a smaller video window by resizing your video player to 1/4 of your screen, or no more than 720×480 pixels. You can select a lower zoom level for your browser. This won’t affect the video quality (since video is scaled UP from smaller sizes to fit a full-screen picture). This will require less computer power to capture, which will make for smoother videos."
because my video window was huge when I recorded it oooops
