I have 2 containers; 1 is a title container with 4 text tracks and the other is a 3d container with 4 still image tracks.
I'm creating the effect outiside the host program and realized I needed to make the duration of the effect longer...30 seconds...so I could add some more stuff after 20 seconds. I thought I could pull the last kf on each container track to 20 seconds and then all the tracks inside the container would re-adjust. But that's not what's happening. The original tracks are playing out for the duration of the effect - 30 seconds.
