I have edited video from 4 minutes down to 1 minute using In, Out, Extract.
Viewing the final (test) movie, I'm seeing flashes of the unwanted film showing up.
I zoom all the way into the film on the timeline and can't see it anywhere. If I open the trim monitor then I get totally lost.
Adobe Help does not help me understand the trim monitor well enough and I obviously don't want to start all over again.
Where are you seeing these "flashes?" If in Transitions, then it is likely a lack of adequate Handles on the Clips that are retained. The trick is to move your In & Out points slightly, where you see the "flashes."
This little bit will give you an idea on Handles:
Here is a graphic on Handles:
Hope that this is all that it is. With GOP footage (often MPEG's), there can be some really odd behavior. What are your source files again?
Hey Bill - thanks so much for your feedback. Very interesting lesson. The issue I was having is like a teeny tiny split second of the removed film appearing in between clips. I realized the error I made was by checking the DeInterlace button because I didn't really know the difference. I read up on it some more and unchecking the button seems to have solved the issue I was having.
(hate being a noob!)
