Playback starts at the beginning of the timeline and NOT between the I & O points
Hello there!
This is the 1st time I'm having this issue.
Whenever I press <return> to render between the I&O points, Premiere (after rendering) starts the playback at the beginning of the timeline and NOT at the IN point. This is definitely (for me) not a functional way to work.
Any hint on how to change this?
Thanks in advance.
