I have used one channel as a very small image-in-image movie in the main channel. In the preview this thumbnail-like image looks fine, but after exporting the movie this thumbnail looks distorted and unsharp; As if you blow up an image greater than the original.
The clips I use are the same as the clips I use in the other channels.
I cannot find any instructions on this subject. So where to start in solving this?
See the thumbnail in upper right corner through out the movie after.
