Hello guys, hope you can help me.
So basically I got this short video of me and some friends, and what I wanna do is to replace the face of one of my friends with another picture -in that case the picture of another of my friends, but let say it's a potatoe for the sake of understanding.
So I found how to overlay a picture onto iMovie, it´s pretty simple when its not suppose to move and the picture is square sized.
However I'm facing a few problem that I seemingly cannot overcome:
First of all, the picture of the potatoe that I wanna insert. I can only crop the picture to create a square shaped picture, or as you can imagine my potatoe is not square sized and I do not want any potatoe field background to appear. So right now when I import the potatoe into the video it's not "clean".
So what is the preliminary work I should do on the picture before inserting it into iMovie? I tried paintbrush and iPhoto without finding satisfying tool.
Second. Once my picture is clean (no field is showing), I can put it in the video, it's picture in picture tool. But how can I change the position of the potatoe frame per frame? Because of course people are moving in videos.
Thank you very, very much guys :)
