nnnnnn... yes maybe.
If you take the bodie and rotoscope it out you can easly crop it and place it on the video in a different layer (if you mean that).
As for skittles, is this the method to crop the bodies with animation and makie it a layer?
Yes you will need it. I guess Koop made all the rotoscopeing in Photoshop and loaded an image sequence (or every image alone, I don´t know if Magix supports image sequences) into Magix (or it already has a vetor tool today).
Its just too perfect that cropping
Maybe it was already the original size of the source.
i dont think he crops all the frames...
You don´t have to add the settings to every frame. There are some ways to avoid it (image sequences, project sequences in Premiere, or simpel videos with RGBA colourspace). *shrugs*
In the end it´s often not more than simpel Ctrl+C and Ctrl+V to paste the settings over all the images. Fast and simpel.
