View Full Version : Lossless GUIs?

Goal: Back up DVD ripped VOB (and, ideally, anything else) losslessly into container-held formats.

Presently I am using Handbrake with 2-pass, de-interlaced, 100% "Constant Quality" to create anamorphic XviD+AC3/AVI (which is then direct-stream copyable into anything else via 3rd-party utilities). This generally results in DVD rips which are about 50% of source size. While the file sizes are still quite big, this is ameliorated by the fact that blank plastic is cheap, encoding is very fast compared to x264, the video looks really, really good, and you needn't worry about whether Grandma's old computer can handle playing it (because you know it can).

However, it's not truly lossless even if my beady, bloodshot eyes can't discern a difference, even when blow way up.

What out there, if anything, can rip losslessly while preserving display characteristics of the source (e.g., anamorphic), can pass-through AC3 (or encode with audio off), and doesn't require a degree in rocket-surgery to operate? I am more interested in encoding speed rather than smallest possible resultant file-size.

Using a lossless codec will always give you filesizes bigger than the original, so backing up the DVD 1:1 will be more efficient. I don't use those 1-click ripping solutions, so i don't know exactly which one supports what codec, but MeGUI supports snow for example, which is a lossless codec. x264 also has a lossless mode that shouldn't require that much processing power because it doesn't use many of the advanced features. Other popular lossless codecs include ff1v (from the ffmepg project), huffyuv and msu lossless.

Approx. how lossy are the MPEG4 codecs (and newer competitors such as Theora) when used at maximum quality setting as described in the first post? I can certainly live with 50% file-size2 if the loss is 2%....

Why don't you just leave the dvd on the hd? That's 100% the size with 100% quality.

Personally I use the free version of DVDFab HD Decrypter, to back-up my DVD's (in Main Movie mode) as .ISO files :)

You need 2 tools: one to demux the video (m2v?) and audio (ac3) out of your vob, and another tool to mux those two into your favorite container (avi). Max speed with smallest lossless size. May not fit on DVD5 if source is DVD9. I'm guessing DGIndex can do the demuxing; don't know what tool can do the avi muxing. I don't know if AVI supports anamorphism; if it doesn't you can use mp4 or mkv instead.

or to do it all to MKV for you,

DVDMenuXtractor.

Does everything for you, and puts it into a neat little mkv for you.

This is just for de/remuxing, there is no encoding whatsoever, so 100% original quality.

DVDMenuXtractorIs that named right? (I'm having a devil of a time tracking that spelling down to a runnable app on Google.)

What (else?) permits ripping individual chapters into either VOB or mpeg2, preferably without having to back up the entire movie file to do it?

I think you should clarify your target in first place. If you are encoding to a lossy format, it's never a lossless process. If you would transcode DVD to lossless format, it will have probably more then 50GB. I think this is not something you want to do.

If you want to have a lossless copy, then just backup the DVD. I absolutely don't understand what you're trying to do...

...or simply rip to ISO !
