Shane,
Thanks for freely sharing your expertise. Of course, I had already “blundered” my way through the process, working on a project for my in-laws, but it was cool to see that I had figured out on my own the right way to do things.
Regarding the 12 frame adjustment after setting the cross dissolve, I found a more precise way to do it was to move the playhead to the beginning of the clip, enter new keyframes (duplicating the originals by default), clicking the “next” keyframe arrow and deleting the originals – repeating the process for the outpoint. This was truly a blessing when I had reached the 2AM, bleary-eyed phase of trying to get the project finished.
Thanks again for sharing.
Marc
