View Full Version : 2 Hour Vid = 3 Gigs?!

Hi all,

New to the forum, and any help would be much appreciated. I was trying to encode The Matrix. The VOB file was about 5 gigs, and to get the best quality, I used the 480x272, 768kbs 2-pass setting. The first pass seemed fine, and the file was about 800mb at the end of it, so I assumed that the final file would be about 1GB. However, the rest of the process took 3 hours (!) and the final product was a hair under 3GB, way way bigger than I was expecting, or seems normal.

Could anyone explain what I may have done wrong?

Thanks,

I tried again, this time using 480x272, 768kbs, 1-pass, and the file size, as expected, was just under 900mb, which is great. What isn't was that the audio was out of sync. I'm almost a total newb at this so, as I said, any help would be greatly appreciated.

P.S. If I'm not supposed to be posting questions like this because this is a beta, if someone would let me know (to stop being so annoying!), that'd be cool...

I would give the 2-Pass encoding another try on that file or another. A similar thing happened to a couple of movies I had encoded using 2-Pass. When I tried again, everything came out much smaller (around 1 Gig for each movie.) I think that the process must not have fully completed and stalled before writing to the proper size at completion.

Ya try the 2-pass again. I haven't seen the "bigger file than normal" issue yet. As for the audio try adding "-async 1" as part of the CLI parameters in the profile you are using. If it still doesn't sync up nicely. Try forcing the framerate to mach the VOB's framerate, meaning don't use Input as the framerate.

This happened to me as well, i noticed when it was encoding the 2nd pass the bitrate had jumped to something like 16056. I've had issues with 2 pass encoding, but for the most part 1 pass seemed fine. I wonder if it has something to do with having both AppleTV Profiles and PSP profiles in the program.

Thanks so much for the help. What I ended up doing was converting the .vob using AutoGK. The audio sync issue was fixed. Unfortunately, it created a 600x272 file, so when PSPV9 converted it, it was stretched. When I get round to it, I'm going to redo it so it creates a 720x480 file and then hopefully I can finally watch this movie on my PSP! I've only seen it, what, nine-hundred times?...

Thanks again.
