Apply effect to part of a synchronized clip
Hi!
I created a synchronized clip out of two clips and created a picture in picture for my video. I split the synchronized clip to cut out some content and applied a transition to the cut point. I later realized that I wanted to apply a reduced opacity to the picture in picture video as well as other changes to the background clip. I viewed both original clips in the timeline and applied the opacity reduction however it appears to only be applied to the first part of the split clip. The next part (after the cut point) lacks the modifications made to it. When I arrange to have the timeline show the individual clips, I can't modify the second part of the clip. Everything after the cut is sort of greyed out.
How can I modify the individual clips in the synced clip after this cut point?
Thank you in advance!
