More info after playing around with it:
It seems to “hiccup” at the same places regardless of my render settings
EXCEPT when I render it at 30fps as opposed to 29.97 fps… but at 30fps it hiccups at different spots.
I tried setting the AVC render to 59.940 … I just rendered a section and the hiccup seems to be gone.
However I need to render it around 30fps because that’s how it was shot. But when I tell vegas to match media settings, and point it to one of my clips, it sets it at 120fps (which i know isn’t right) but sometimes at 29.902…. so maybe that is the real target fps?
this is all very confusing
