I do not work in this program unfortunately. But now I looked at the technical specifications and description the program – it has the same capabilities as any editing program. And can work with mode overlays. So I’m sure you can use this product. Thank you/.

It’s simple. In any editing program or After Effect. Can ask google like a – “how use luma mask for transition”. As example: https://www.youtube.com/watch?v=F3N_ueWc3fE or https://www.youtube.com/watch?v=oHa4MrXc0nM or any other tutorial. Thank you.
