If you want a glimpse of the editing process, watch me edit "First Date" for the Buffy season 7 video...
Before: Just the clips cut in chronological order with no editing
[3:36-7:07] Sped up (10x) moving clips and adding transitions and extras
After: The finished portion!
(I had to move everything over to a new project file before recording the "after" because my computer was seriously glitching from running 2 programs at once, lol)
