Thanks for the notice @katrina-ariel! In case you're interested here's my software Movavi video editor 12 Youtube Link it's just a cracked (unpaid but hacked) version because no such video collage maker that's free nowadays just exclude the software from your antivirus scans because it's marked as a malware and AV's deletes them but it really doesn't have any sort of virus.

I'm telling you this because i know you'll rock these video collage thing 100x better than mine.
