I recently installed Golden Videos to replace PowerDirector for converting my VHS tapes to computer. I like the program so far, but I noticed that the mp4 file sizes for Golden Videos are about half that of the MPG files of PD. My concern is that the quality of the MP4 files is lower, but I don't know.
I have plenty of disc space and am more interested in quality than space utilization.
I don't know much about file types, so that doesn't help.
