I don’t know why. But I’m experiencing this thing where if I go into Sequencer and create a new shot and then add a camera, it automatically sets the playback range from 0.0s to 0.0s and there’s no way to change it.
Can you attach a screenshot of your sequence?
It might be that the master (the sequence that contains the shot), is trimming the shot in some way which doesn’t allow you to adjust the playback range of the sequence in the shot.
Is the playback range settable if you use the hotkeys ‘[’ and ‘]’ or use the menu items to set the values directly? I’m wondering if it’s just a hit test/dragging problem when the red and green bars are really close to each other (although I haven’t encountered this problem before).
