Is it possible to use in Movie Edit Pro 15 Plus one type of transition between scenes (for example door) more times for specified film project?
Normal it is possible to use only standard crossfade more times.
I believe you can use any transition you want, as many times as you want... there is a dependency on the computer performance for these 3D transitions.
If you have a lengthy project, you might want to break it down into shorter segments, then complete each and export. In the end, bring all together in a final project using the transitions again between the exported pieces.
But, I have used the same transitions between objects before, it works just fine.
I have another problem. I have three scenes, for example, lasting 5 seconds (1, 2, 3) and I want to do door-type transition between scenes 1 and 2, lasting two seconds and take same type of door-type transition between scenes 2 and 3, lasting 2 seconds. The effect is that the first transition is a door-type and the second is the standard crossfade.
