Julien Bayle's icon

hello,
I found some posts about jit.gl.sketch and other object/method to make png masking and background, in front of & behind a video (or multiple videos)

What would you suggest?
I'm looking for the global concept and I'll implement it :)

any ideas, tips, advices (links) would be appreciate :)

coming from you, I think it is the best method to use.
I'll go for it!

thanks, rob!
