Max Compression

[Magua]

I am trying to backup the Indiana Jones box set and would really like to have it on one disk. The Raiders of the Lost Ark disk has almost no special features, the menus are pretty cool looking but I plan on just doing the movie to save quality. The movie is only 115 minutes, well under the length of some of the longer movies I have put on one disk with very good results. However, the movie only is over 7gb, which is larger than most...I assume this is because it has a higher bitrate (forgive me if I make wrong assumtions, im fairly new at this stuff). By the way, if it matters I am using a Plextor 708A with Arita 8x DVD+R disks, DVD Decrypter to DVD Shrink/Nero with deep analysis.

So anyways, how do I know what the bitrate or resolution of a particular film is? And, since you can't talk quality terms strictly by compression amounts (75% compression on a low bitrate film will be significantly different than 75% on a high bitrate film...correct?) what kind of bitrate will produce an 'almost identical' copy (again I know its not possible if you compress at all, but if you can't notice it is perfect for all essential purposes). Im about to try Raiders of the lost ark, its 63.3%, which is a bit low for my liking.

Thanks

ive backed up this movie and at first i was concerned about the pq but dvd shrink did a great job. I couldnt tell the different. The compression ratio was around 65-70%. You could also try using a dvd+rw and see how the results turns out.

As you point, the importart figure is not % compression but bitrate. I have compressed severar 3 hour movies ( LOTR, TV series) up to a bitrate of 3000 kbps (45%), with superb quality, using CCE.

If you have a good source you can compress a lot, if you have a bad (low rate) source a little % compress can spoil the whole thing down

You can check bitrate of your source with BitRate Viewer.

Thanks, that bitrate viewer is a pretty good program. I just backed up X2: X-Men United (2hours 13minutes) and was around 75% compression, the original averaged a bitrate of around 7400, the backup was around 5800, and looks great.

Is there a set bitrate that would be needed for a good looking backup? or does it vary from movie to movie?

Don't tell me your trying to fit all 3 movies onto 1 disc!?!?!?!! I'm probably wrong, but that's how it sounded. :P
Just use DVDShrink, re-author, keep the video and 5.1 audio, drop everything else. I haven't ripped these movies yet, so I'm not sure what kind of compression your going to get, but give it a try.

Haha no, each movie is on its own disk. The movies are quite large, although they are only around 2 hours in length, which led to a fairly high compression ratio. Anyways, I just finished watching all three backups, and they all looked great. I only kept the main movie with AC3 5.1 audio, and trimed out most of the credits using DVD Shrink.

What's wrong with that? I have the entire Back to the Future trilogy on one disc as well as the Star Wars trilogy and Indiana Jones trilogy (seperate discs, of course). The quality is obviously lower than on a normal backup, but for everyday viewing it works fine for me... In a few cases you can see some artifacts, but you can't win 'em all, can you?

There is no star wars trilogy on DVD yet

There is no star wars trilogy on DVD yet.

There is when you rip it from LaserDisc...

Since this is the DVD to DVDR forum I thought it was safe to assume we were talking DVD's here. The picture quality is very different to start with anyways, apples to oranges.

Yep, the Star Wars Trilogy is officially going to be released this year, on Sept. 21. You CAN actually get it now, if you buy the Region 5 (Or whatever Asia is).
