pure back ups? loss-less "how to"?

[darw_n]

this is a dumb question I think, but searches and faqs aren't helping too much...

how do I take a DVD and strip everything un-wanted and make a playable avi, ***without*** any recompression?

I want to make a loss-backup of my library for a media server.

space isn't an issue, I want nothing but the movie and the main audio, not even a menu.

I have a sneeky feeling it is super easy, but before, I was backing up and compressing, so I have never done loss-less backups.

any help or links would be greatly appreciated!

thanks

Basically the same as for any other DVD -> AVI conversion (see the guides), except choosing lossless audio and video codecs instead of MPEG4, MP3, etc. There are several decent free lossless video codecs like Huffyuv, as well as (of course) uncompressed RGB. For audio I'm not sure, you might have to go with uncompressed PCM.

BTW, why do you want to do this when the original DVD (.VOB files, etc.) is compressed and much smaller than the uncompressed AVI would be? You could use DVD Decrypter in IFO mode to just back up the main movie, unless for some reason the AVI format is a must. I hope space really isn't an issue, because uncompressed video uses truly massive amounts of HD space.

...uncompressed video uses truly massive amounts of HD space...Yep. Do the math. RGB is 24 bits (3 bytes) per pixel. NTSC DVD video = 720x480x29.97 = 31,072,896 bytes per second, or 104.2 gigabytes per hour.

PAL = 720x576x25 = 31,104,000 bytes per second, or 104.2 gigabytes per hour.


If you just want to play DVD's from a hard drive, follow Doom9's HD Playback Guide (http://www.doom9.org/mpg/hd-playback.htm).

the backups **need** to be in AVI format because I use xbox media center as my front end and playback, and it does not fully spport DVD file playback, making ISO playback undesired, and having a video_ts folder is out of the question.

Because of this (having the backups stored on a server, and the xbox streaming them, along with the xbox's limitations with DVD playback), I can not follow the standard "HD playback guides)

thanks for reminding me about raw decompression, I worded my original question wrong:

could someone point out a guide where I can extract the same quality (exactly the same quality) video and audio and contain it as either an avi or a mpeg file?

I still might not be wording this correctly, but I am having a hard time figuring out what guide to follow.

Hi-

You can use The Stream Processing feature of DVD Decrypter to demux the video .m2v and the audio of your choice. Then use bbMPEG to mux them back together into an .mpg file. Here's a guide, but ignore the stuff about splitting, as it was written for splitting SVCD to CD-R:

And here's bbMPEG itself:
