Adobe might consider this an "idea" but guys, it's a BUG, and one that should have been taken care of decades ago.
Premiere automatically adds 1 frame before the out point when you set an out point. WHY?!?!??! I've been using Premiere for 15 years for national commercials, and every time I export I have to bump in on the timeline to make sure that I physically move the end point, because if I just hit "O", it adds a frame.
Please guys, this is one of those silly little changes that should be addressed easily. At the VERY least it should be a preference option. One more reason to start playing with Davinci I guess, as if we needed more...
