I’m revisiting this post as I still have the same issue. When I try to export a still in FCP using Quicktime conversion, it looks fat. Is it a simple matter of video pixels being a different size than square computer pixels? But since I’m viewing both images on a Mac, it shouldn’t really matter…
Also, in regards to the kid, his head is that long. He has an “unusually” long head. I compared it to still photos I have of him.
