A new approach to InstantCopy?

[henweigh]

Hello All,

I've been working lately on backing up my DVD set of Deep Space 9 episodes. I've been playing around with using InstantCopy to back up the DVDs.
No matter what settings I use in InstantCopy, I always end up with a much LARGER iso image than is predicted. I thought this was unusual considering most people on this forum seem to repoirt SMALLER iso images than predicted. (By Larger I mean my iso images end up being 5.7 gigs).

I then thought to myself, "Self, why don't you now use a tool like dvd2one to shrink that large iso image down to 4.3 gigs?" It seemed like a good idea because I figure the quality loss going from 5.7 gigs down to 4.3 would be less than using dvd2one from the full 7.9 gigs down to 4.3.

Unfortunately, dvd2one gives me a windows error and crashes about 12% into the process.

1. Does anyone have any experience using InstantCopy and dvd2one together to create an image? If so, did you notice any quality improvments over using dvd2one by itself?

2. If anyone else has backed up these DS9 episodes (or similar), I would love some helpful advice (success/failure stories). I am looking to back these up using 1 DVD9 : 1 DVD5 ratio (i.e. 4 episodes/disc).

Thanks :)

You'd get much better quality going from the source to dvd2one than with going from the source to IC to dvd2one. Besides, in my experience dvd2one doesn't handle DS9 very well (it's hybrid FILM/NTSC), and there are some weird effects associated with not deinterlacing/IVTCing very well.

It could be an IFO error, I hear IC doesn't edit the IFOs correctly, and DVD2One needs correct IFOs. Test out that theory by compressing the source with DVDShrink, then running the DVDShrink version through DVD2One and see if that generates the same error at 12%.

Do you know how to use IFOEDIT and IFOUPDATE? Then its easy to reduce the size of your "oversized" stuff that IC7 did and it looks GREAT. This is abbreviated but look at a previous post of mine to see more details:

For picture by picture on how to do this just look at barryhl's guide on vcdhelp.com

I always look to my extras first in order to reduce my movie FURTHUR to 4.37 gig. If that doesn't work then I goto main movie.

1. Separate the part you want into a different folder called "input"
Create another folder called "output"
a. Just move the vts_0x_1 through whatever..dont move the vts_0x_0 vob.
2. Run ifoedit and pick the vts_0x_1 vob and create IFO's...to make it go fast, drag the progress thingie down till you cant see the bar anymore...its amazing how fast it goes then lol.
3. Rename (if you have to) the vts_0x_1 to vts_01_1 through whatever
4. Open up dvd2one and process your Input folder
5. Take the output folder and (rename them to original names) move it back into the output of IC7.
6. Run IFOupdate and update IFO's and get vts sectors
7. Thats it, now burn with your favorite proggy

All my oversizes have looked great doing this method.

@neo_sapien: I know hybrid is a problem with external encoders, due to framerate changes. With those processes you have to somehow make the video all film or camera, which got you into deinterlacing or IVTC. But these programs should not have any problems, since the structure, including pulldown flags, is maintained. ReMPEG2 had no problem, as I remember, with the correct IfoEdit (version 0.6).

As I said before:


You'd get much better quality going from the source to dvd2one than with going from the source to IC to dvd2one.
