Hi, I am looking for an application that can interweave frames from 2 opposing videos? For sake of description let's call them video 1 & 2. I am hoping to upload a gif to explain, (Like Rod sings every picture tells a story) I am also, looking for a way to speed up to say 120fps or down to 10fps. This will allow me to have areas that are fast and slow in different areas of my video
