do your dvd2one rips look better than svcd rips of dvd scr?

[azuberi80]

im thinking of buying this dvd2one program but i had one final question. ....im sure most of you seen the dvd screener rips that have been coming out because of oscar nominations and stuff....the only thing is i hate to get up in the middle of a movie to change discs.

now these are pretty good quality to me (i know definition of "good quality" is different for everyone), so how does a dvd rip with dvd2one compare to a svcd rip of a dvd screener?

keep in mind i want no subtitles, no menus, no extras, one audio track and one angle.....the bare minimum....the movie with chapter marks and thats it.

@azuberi80, simply put, if you are happy with the quality of the screeners, then you will be thrilled with the output of DVD2ONE, even on a 5 hour movie. Buy it now!

cool.

another question. i got a sony surround sound dvd player with five or so speakers and all that.

i want to know which audio track to rip that will allow me to still use the surround sound feature.....basically what is the best quality audio track?

[ghoster]

well in that case you should keep the 5.1

anyone else care to comment?

the way people were talking i was thinking the dvd2one was making files that looked like 100 meg asf files.

Dvd2one transcodes, if necessary, to get a dvd9 movie copied to a dvd-r(+R, etc.) disk. The "quality" of the result is directly dependent on the bit rate used. The higher the bitrate, the higher the quality. Obviously as the bitrate goes up, the file size increases, which means you will get less og the movie on a disk. I'll give you an example (note in this example I will use the base 10 definition of a megabyte and gigabyte which means that a dvd-r will hold 4.7 Gb of data; the base 2 definition yields a max of 4.39Gb):

Suppose you have a dvd movie that is 2 layer. That means that there could be up to 9.4Gb of information. For this example, lets assume that it is indeed the full 9.4.

If you remove all the extras that come with the dvd (storyboards, deleted scenes, alternate endings) the actual movie file size might come down to 6Gb. If you now remove the multi-language subtitles, and the multi-languages themselves and the director's comments, that number might come down to 5Gb. Still too large to fit on one dvd-r.

Let's say for the sake of this discussion, we stick with the 6Gb number.

With dvd2svcd you can transcode to svcd standards at say 2500Mb/sec. DVD white book specs are between 5 and 9 Mb/sec. Again for the sake of simplicity let's say your particular dvd it coded at 7500Mb/sec. Therefore when you transcode to svcd your resulting bitrate will be 1/3 of the original. Svcd looks pretty darn good, but it is not dvd quality. You will have used 3 cd-r's disks to do the job. The transcoding process will take on the order of (based on your processor speed) 3 to 6 hours.

DVDXCopy does NOT transcode, therefore the original bitrate used to make the dvd is the same bitrate you will get on your copy. However, since the total file size is 6Gb, you will be required to split the movie and use 2 dvd-r's. This entire process is done automatically inside the program. The result is a perfect "quality" copy of the original. Incidentially the total processing time without burn is approximately 30 to 45 minutes.

Dvd2one incorporates a transcoder which takes the 6Gb file and reduces the bitrate(transcodes) to a rate such that the entire movie will completely fill just 1 dvd-r. In our example case the file size would have to be reduced by a factor of 4.7/6.0. the bitrate would therefore go from 7500Mb/sec to 5875 Mb/sec (more than twice the rate of the svcd copy). As that 6Gb figures for the movie goes lower (by removing more junk, which dvd2one allows you to do) the final bit rate of the copy will go up and therefore the quality will imporve even more. Going back to our example where we also removed all the extra language crap and got to a figure of 5Gb, the numbers would now look like this: 4.7/5 which yield a bitrate of 7050 Mb/sec. As you can see, this is approaching the original dvd specs. The transcoder in dvd2one is spectacular. Typical transcode time are on the order of 10 to 20 minutes. The results are fantastic.

For a test, I choose "Mission to Mars". this movie contains a lot of scenes that are great for comparison for quality. The minirover on the martian surface when we first see it with the hugh canyon to its right and rock formations in the foreground and in the distance. Details inside the rescue ship. The space station in orbit against a field of stars, etc.

I made of copy using DVDXCopy and a copy using dvd2one. i then played all three in my Toshiba Ad6200 progressive scan dvd player on a 65-inch Toshiba HDTV. No one could tell them apart. No pixelization, no stutter, no nothing. Even with my most critical eye, I could not see any differences.

An important issue to remember is that as the actual movie file size goes down and approaches the 4.7Gb threshhold, less bit manipulation has to be doen in the transcoding and the resulting gets closer to the actual rate the original was recorded in.

There are some problems with a select few dvd's that can't be copied in one vs. the other program ( a very few), but by having both available I can choose which program I want to use.

Now that I have said all that, let me also remind you that there is a free program DVD Decrypter that you can use to rip a dvd. Part of that program is an option to do both an ISO read and an ISO write. If the dvd is a single layer movie, I simply do the ISO rip followed immediately by an ISO write and I am done.

If you're happy with the DVD screeners of the "Oscar" discs, then you'll be happy with dvd2one. I personally think that the rips are at least SVCD quality. It is BY FAR not DVD quality. But then again, it would depend on how long the movie is also. So far I've only done one rip with dvd2one. I backed up the DVD I had of Black Hawk Down and my opinion is based on that one rip. I still want to try other movies and see if the quality is the same(I feel that it will be).

I'm just a newbie at all of this, but I've perused through many forums and have done my research on what programs to use, how they work, and what problems people have had, but I'm a stickler for quality.

chips: that was a great post, exactly what im lookin for.
