Hi again. Can anyone point me to some info (another site, an old thread maybe, here or elsewhere) about just how many .mp4 codecs are actually in Nero Recode? I gather at least the two audio codecs (LC and HE) and maybe two video (normal<?> and AVC)? I see on the Nero (formely Ahead) web site that AVC is (I think<!>) a new standard for HiDef? How does this apply to the regular use of Recode for the average user?
I find that it takes about 25 minutes or so for Nero to turn a DVD9 ripped to the hard drive into a DVD5 on my system. I seem to be making .mp4's just faster than real time. I tried the AVC codec profile (same file, same target size), but after 30 minutes it had only encoded 6 minutes or so of the movie. Why is it so much slower? What does this codec do? Is it better - I mean, same quality at smaller file size? Or just more compatible?
DVD's are so cheap now, I'm wondering if going to .mp4 is even worth it.
I've been using the .mp4 abilities of Recode so far to back up my lesser favorite movies (ones I didn't want cluttering my shelves, I guess). And I've been figuring that I get pretty good quality setting them to final file sizes of 1/3 a DVD5. But I honestly have no idea how to determine the most efficient file size. Heck, I made one movie that was 3:4 aspect ratio (i.e. full screen) the size of a cd and it looks pretty good, and almost everything I do is widescreen. Surely<?> a full screen movie requires more data per frame than a letterboxed one of equivalent resolution? I've got almost a terabyte of hard drive space now so I've never been much concerned about file size as far as a storage issue.
What I want to know is, say I have a 2 hour DVD movie and I want to make an .mp4 using Nero Digital, and keep the aparent quality of the original movie.
What size file gives Nero enough space to keep all the quality of the original but also just does this. I mean, if "x" mb's equals DVD quality, then "x" + "y" doesn't make it any better, so I don't want any extra "y".
I understand this is a tough question since all DVD's are encoded at different compression rates. But I imagine there's got to be some sort of a ratio I can use. For example, is ND .mp4 "x" times more efficient than mpeg-2? If it is twice as efficient, than I would imagine if the original disk held 4 gigs of data for the main title I wound want a 2 gig file for the .mp4. Does this make sense?
If I found out I gould have original quality in a much smaller size, it'd be kinda neat putting most of my collected movies on my computer for instant recall; just like my CD collection has migrated to the pc.
Thanks for staying with me.
Now, have you got any answers for me?
