nevermind, when I was finally able to convert the AVI to mp4 (which was a long struggle in itself), I saw how the pitch bend shows up in the video now. Maybe my eyes were playing tricks on me before but I think it didn't show up in the preview. Also a different problem I've now discovered is when the slide does get activated, it resets the position of the note back to where it was before it started playing, if that makes sense. Then it slides from there, instead of the position it was already in after the note was hit. This causes slides to be even less apparent, and sometimes even appear to be sliding up when the opposite is occurring.
