You might consider making little movies that are transitions of the style you want, then you'd but the in and out marker together at the transition, and drop in that transition movie clip if you want some other style than the 9 offered.
Can you be more explicit regarding this suggestion?
What you are implying sounds interesting, but I need more detail.
Do you have an example movie file of the type you are suggesting I make?
You make it sound like there is a well (or something) that I can drop a transition movie onto.
Some applications I have seen use a method where you are told to make a gray scale movie that will ultimately map it's pure white pixels to movieA, and the pure black pixels to movieB, and all the grey pixels in between will be a mix of the two. Where, for example, an animated gradient that starts out all white, and then animates the mid point across the screen from left to right, so that it ends up all black, produces a simple wipe effect. And these applications then give you a well to drop your grey scale animation into.
But, I do not know of a way to assign a custom effect animation in Videator as just described - or is there?.
Your explanation needs to be complete enough for me to get how to do this.
Sorry, if I'm missing something obvious here.
