Ok, I tried a couple of settings and the default ps3 profile at 1 and 1.5Mbps seems to work fine.
I am not completely happy with the resolution, though. The profile max setting is 720x400 at 1.8 AR... but the movie I tried is 852x480 (widescreen), as well as some others I have around here. I am not sure what the limitation is but the fact is that I was playing with it last night, managed to transcode an 852x480 movie to the same resolution MP4 with
DVDFab but it does not play properly on the PS3. I get a blank screen, even when PS3 initially seems to recognize the format. Audio works fine.
My question is: can DVDFab take 1:1? why resizing? And why 720x400 or 704x400?
I'll be happy to betatest and make any tests you guys can think of, i'd really like to get to a stable ps3 profile that enables me one click transcoding of my movies so I can store them in the ps3.
I guess I could also look into header differences if I knew of a good .mp4 container validator, but othern than the prehistoric mp4UI i'm out of ideas.
