I am running Sony Movie Studio 12.0 and really like it. It does everything I need in producing videos.
I have a video, created from an Avi produced by Morpheus with audio added via Movie Studio...the video is about 4 1/2 minutes long. When I render this timeline in Movie Studio as an MP4, if I choose to render as Internet HD 720, it produces an MP4 of 265 MB. When I render this same timeline as Apple 720p30, it produces an MP4 of 69 MB, ie about 4 times smaller. When I view each of these rendered MP4 files, I can see no difference in quality. One would think that an MP4 that is 4x larger would have much higher quality, but no. Any thoughts on whether there is really a quality difference in the Internet HD 720.
