I rendered a part of my video to see how the animated (flowing) text would look. This was 40 seconds out of the video, but took 10 minutes to render. Is it normal for the type of text animation I've used to take that long to render? most of the videos I render take about 1/2 the time of the video to render, but this is excessive.

EDIT: It also shows it rendered 148MB, but the resulting MP4 file is only ~48MB
