Quality difference between ripping programs??

[videobruce]

Is there any QUALITY difference between all these different ripping programs?? I don't mean quality of the program, but the lack of visual loss of detail and compression artifacts with the copy vs the orginal.

Has anyone done a comparision using the same movie (same size/length)?

Thanks in advance.

When ripping a DVD to your hardrive for backup, there should be no quality loss regardless of what program you use. It should be a direct copy of the original DVD. What you do with it after the ripping is what causes quality loss.

Then you are telling me it's the 'burning' program that makes the difference??

I believe he is telling you the difference is w/ the transcoding program you use to compress the DVD. Some are alot better than others

Which then is the burning program??

I think that maybe you might need to read some of the guides and such that are on this site. The burning program, a dedicated burning program, will not affect the quality or size of your backup DVD. After you rip the DVD to your harddrive, you will most likely transcode/re-encode the DVD to fit a DVD-5. That is where the hit to the quality will come into play, depending on how much squishing of the video you have to do. Ripping and burning have no affect on your quality.

If you are talking about the process of compressing the movie to fit into one DVD then I like to use DVD2one. It's a little faster than most other programs, and I think the picture quality after the movie is compressed looks the best. I'm comparing it to DVD Shrink and Instant copy.

I did a single test between DVD Shrink and Clone DVD and on that DVD (three "titles" totaling 3' 10") the Clone DVD version has less compression artifacts. It was a 4x3 Showtime series that I used at the time.

Individually:

1. The act of ripping is simply transferring the contents of the DVD to your hard drive and removing the encryption. There is no change to the video or audio quality.

2. The act of burning is simply transferring the contents of your hard drive to DVD. There is no change to the video or audio quality.

3. The act of transcoding (or re-encoding) is where the video and/or audio quality can change. Usually it is in the form of squeezing content to fit on a lower capacity disc than the original.


The problem is when certain programs combine two or more of the steps above that the seperate processes get intertwined.

Always good to get more than one opinion. Ever go with the first estimate for a collision job or a house remodel?

.........and your point was?
