Lately I've taken to use H.264 AVC(MP4) to render sequences for a video I'm putting together. I figure MP4 to be a lossless file type(meaning I don't expect it to degrade after a couple of renderings). The camera I currently use is a Canon Legria HF R506, which shoots video in either AVCHD or MP4(selectable between either), so I've selected MP4. When I import the clips to my computer for editing, those clips show up in my "media library" with shadow files still generating(corner pip going from yellow to green). My problem is not with the shadow files, in fact, I find I can pull the clip onto my timeline and trim it down as needed even while the shadow file is still generating.
It's when I've created my sequences of roughly 5-to-10-minute lengths and rendered them as MP4(H.264 AVC) that I note there has been no shadow file created along with them. I chose MP4 as the rendering time is about the same as if I'd rendered at MPEG2.
I've taken to using MP4 to render sequences(segments, if you will) because sometimes they may have PiP superimposed video showing a scene from a slightly different angle. This thing with shadow files has sparked my curiosity since I started using that Canon camera. As I said earlier, the shadow file creation doesn't impede my editing work, I'm just curious as to why MP4 video I've created does not have shadow files attached.
Cheers!
