I'm wondering if it has anything to do with my sequence settings, fps settings, etc.
Perhaps, but we will need to know what the source footage is, and also what the Sequence Preset is.
My first guess would be a lack of Handles, but you seem to be experiencing these "flashes" with butt-cuts and not with Transitions. Is that correct?
Just in case, take a quick look at this ARTICLE, so we can rule out Handles early on.
Yes I'm just talking about straight cuts, not transitions. My interview footage is in 1080p, some in 60i and some in 24f. The flickers appear when I have other types of images (footage I've collected from people, photos, jpegs, etc.) cut before it. Where do I go to see what my Sequence Preset is?
Someone just emailed me this info and so I'm gonna see if this will help.
"In Premiere Pro CS3 I've come across this problem when the clips were from
different frame rates that were "interpreted" on a different timeline (i.e.
a 29.98 conformed to a 23.976 timeline). It only happened occasionally
where the fractional part of the last frame of the clip didn't match up
exactly with the whole frame in the timeline. It was really difficult to
see until you zoomed into the timeline all the way and saw that the render
bar ended BETWEEN the frames. The fix was to cut off that last partial
frame. In reality it wasn't a "partial" frame, but the way that PPro seemed
to calculate the time index wasn't frame or field dependent and there ended
up being partial frames due to rounding errors. I haven't had that issue
with Premiere Pro CS5, although I haven't tried mixing frame rates like that
in a timeline anymore."
Thanks for that clarification. That rules out a lack of Handles, as I suspected.
