DVDRIP vs Original DVD

[Smith79]

Is a DVDRIP the same quality as the original dvd as if you bought it in the store? I hear a DVD-R is untouched whereas a dvd-rip is not cause it's formated & bonus scenes are gone to make the file smaller.

A rip to DVD9 can retain everything on the original disc in the original quality. A shrink from DVD9 to DVD5 has to lose something. Either the extras, some quality, or some of both.

If you're ripping a DVD or Blu-Ray yourself, you'll get exactly what's on the disc. If you're downloading someone else's "DVDRip" - you have no guarantee what's in it or what quality it may turn out to be.

If you are talking about files you can download off the torrents that are designated DVDRIP, that just means the original source was a dvd. They are often times converted to xvid or h264 to reduce the size of the files. Quality of these varies quite a lot.

A commercial dvd that is ripped straight, without removing anything or converted, will most likely be between 4 and 7.9gb in size. Main movie only will be smaller of course and will average somewhere between 3.5-6gb in size. But the torrent files will be much smaller still.

OK if I bought a dvd, ripped it & converted it to one of those formats you mentioned would I be able to tell the difference between the Original Dvd & the Converted one?

Maybe, maybe not. It depends on how well you did it. You've said nothing about the particular format you're planning on using, the compressibility of the source, how much you're compressing it, your intended resolution, or a host of other things.

But, yes, it's certainly possible to convert to another format so that at first glance you wouldn't be able to tell the difference between the original and the reencode.

The answer to your question depends on a lot of factors and your definition of "difference", as well as your viewing device. If you plan on turning a 8.5GB DVD into a 500MB 640x480 XVID file to watch on your 70" TV then you aren't going to be pleased with the results.

Yes, you would be able to "tell" in a technical sense or upon close inspection with a side by side comparison. If you do it well you might not be able to tell in a practical sense. "Well" means different things to different videos though. The type and amount of compression matters. The type and quality of video matters -- talking heads against a static background can be compressed more than a fast moving sports event in a stadium. If you want to get a compressed rip to look as close to the original as possible, all of these things (and others) need to be considered.
