I did more experimenting with this and used @elusien’s “Mask: Simple shape - Neil” new filter to produce this Matte (black and white) short video (I keyframed rotation, width and height to animate the black rectangle over a white background) :
In a new SC project, I overlapped two clips (one on V1, the other on V2) and applied a “Mask from file” filter to the top clip (on V2), and selected “custom”, then pointed to the mp4 file above.
It works!
Then I made 4 more matte videos in a similar style.
My video below gives more detail and two examples of the transitions in action:
An interesting way of using the filter to produce animation masks - didn’t think of that.
Jon, it’s not really my filter. All I did was edit the user interface to introduce Keyframes into a coupe of parameters. I wouldn’t want to take the credit for the actual filter whose author is Marko Cebokli.
Thanks, @ejmillan and @Paul2 . If you mean that my “Slide and rotate” mp4 files should be included as an inbuilt feature of SC, I doubt if they would, (don’t think matte transition files would be included in the download), but I agree, I think the adapted “Mask: Simple Shape” filter with keyframeable rotation and softness certainly would be a welcome and useful addition.
I’m happy to upload my matte .mp4 files here if anyone would like to use them. I’ll try to put them on here when I get some free time (next day or so).
