This thread:
sparked a few creative ideas in me, so I made this short demo of a photo slideshow with animated moving borders:
In truth, it was quite hard work.
I made an animated mask border:
12 photos in total, with transitions applied (I used my blur/stretch transition filter sets):
Applied SPR filters, then mixed down 3 tracks with 4 photos on each.
Blend Mode (ADD) applied to mask file.
Timeline now looking like this:
The splits in the top track were useful as a âtimer trackâ to easily locate the in and out points of each transition.
Then - applied Crop:Rectangle filters to each track and, because the mask file movements had easing (Quartic) applied, I had to keyframe all the crops manually, setting the âjumpâ to 5 frames. Tedious, but it worked.
Not a quick job admittedly, but it was a worthwhile experiment for me.
