    Hi, I want to rip a dvd movie to divx with possibly the same quality. The divx file size is not important, as long as it's not bigger than the original dvd. I've tried a lot of different programs but I never seem to get what I want. If I manage to get the same quality as the original then the divx file is approximately two times bigger than the original dvd.

    So, I was wondering using which program and which settings can i achieve this?
    Or if it's not possible, can I at least rip the dvd to mpg with the same quality?

    Any help would be appreciated
    Thx

    To mpg - sure. Just rip, then run the rip thru vob2mpg and you're done. 100% the same q as the original video.
    To DixX - can't be done. As good as possible is to use the Target Quantizer mode of the divx codec at a very high setting, but as you've seen, it will not buy you any compression. Stay with mpg if quality is what you want.

    Thanks

    And is there any program and which settings to use that you would recommend to convert the mpg to divx, so that if I could have the divx with the best quality possible with the same file size?

    Use a high target quality setting.

    Especially step 3
    Using the quality mode, you lose direct control over file size, even if it's related to the quality factor. Experiment with the quality percentage, until you arrive at roughly the source file size. But there's no reason to do this - just a waste of time, as the original mpg will always be better.

    I thought a DVD converted to DivX could have half of the bitrate of a DVD and still have the same quality as the DVD since DivX compresses much better than MPEG2. Sure you'll lose some quality by re-encoding but not anything noticable. It's better than using DVDShrink to shrink a three hour DVD9 to DVD-R.

    I just converted a 3 1/2 hour DVD to Divx/ac3 and it looks fine. The MPEG2 was 5042 kbps and the DivX is 2400 kbps.

    Of course, leaving the rip as MPEG2 is the best option if size is of no importance. If file size is important then DivX/XviD is a better option and H264 is better yet but with less player compatibilities.

    Here are 3 tests I did. The first is DivX at 2400 kbps, the second is DivX at 4856 kbps and the third is DVD at 5042 kbps.

  6. I just want to point out that (This is not a knock on DarrellS by any means!)

    1) Differences are not as profound when screenshots are using .jpg compression

    2) Differences in macroblocking & defects will be more evident when you watch the video(s) on a larger screen

    3) Motion artifacts will not be present unless watching the video

    So you'll have to experiment yourself to see if it works for you. My 2400 kbps DivX looks just as good on my 37" TV as the DVD does. Will it look as good as a 1920X1280 HD-DVD on a 52" TV? Of coarse not but it will look just as good as the original DVD. This is not an 800 kbps DivX that you download off the internet. It's a 4 GB file.

    If your DivX files are bigger than the original DVD then you are doing something wrong.

  8. You might include the original source frame as a point of reference.

    Not sure if this will upload. It's a PSD file of the three frames. If not I'll upload BMPs.

    What about "PNG images" for anyone who has a web browser

  12. Thx for the little comparison DarrellS

    In my opinion, the differences are minimal between the DivX encodes (at least based on those stills) do not justify 2x the bitrate. Personally I would just archive the orginal, since HD's are so cheap.

    Don't they have broadband in Antarctica, Midzuki ?

    Midzuki, I tried to upload a PNG image for you but it crashed the website for me. I had to relog back in.

    I guess DVDs are small enough that you could fit quite a few on a 500GB drive. Much easier than trying to fit lossless AVI captures. Hard drives do seem to be the cheapest means of storage these days. Fry's has a 500GB ATA drive for $79.

    You can see a very slight blur on the DivX files compared to the DVD and both Divx files look exactly the same even though one is over twice the file size.

    So why did Blu-Ray and HD-DVD go with MPEG rather than DivX?

    but i belive hd bluray mpeg is not mpg2 like dvd. im sure one uses h.264 codec. this is a great codec but needs good hardware to play. i use my xbox 360. but most of my backups are dvd to dvd and some divx.

    They use MPEG-2, MPEG-4 AVC and VC-1 WMV. The codec that they use is not important to them but rather the blue laser that they can use to create a proprietory format that they can charge you out the A$$ for.

    There isn't much need for a 50GB disc to sell one DivX or XviD movie on. I've seen HD-DivX and WMV-HD that would rival any HD-DVD but you can't make as much money if you put it on a DVD that people could play on a cheap player. Why do you think HD-DVD lost out to Bluray? They couldn't gouge the public for as much money as bluray could with their $1000 burners and $500 players.

    Why are most new players, including blu-ray players supporting DivX?

    The compatibility issues I was referring to were for hardware players and a lot of people don't have fast enough CPUs to play H264 on their PCs, even with a H264 decoder. There are a handful of players that will play H264 but they will cost you an arm and a leg. For a little less, you can buy a wireless media player or you can build a HTPC.

    H264 is the format of the future but right now, there aren't a lot of options without paying a lot of money. DivX is supported by half of the DVD players on the market and it encodes 10 times faster than H264.

    I'm not anti H264 (I stated in my first reply that for size and quality that it's the best option). I just want an affordable player that will play both formats (plus WMV-HD) on a standard DVD that I can burn with my standard DVD burner. I don't want Sony and Hollywood dictating what I have to use to view media on my TV and forcing me to spend thousands of dollars to do so.

    I don't think any players support MKV.

  19. TviX M-6500A supports MKV, too bad its a bit pricey ($400-450 w/o HD)

    1080p res, VC-1, h.264, AAC, DTS, etc...

    hello my fellow piraters lol ive been trying to convert mostly dvd to avi. i came across a program called dr.divx. it was doing very good quality somewhat like axxos but now its been acting up. i seen a mp4 video with great quality and in the range of axxos video size 700mbs (and for the ppl who dont know who axxo is check out mininova.org) question is does anyone know of a program that would do that? im fairly new to the ripping and converting of movies so i dont know to much. auto gordian knot has been good to me. so i tryed just plan old gordian knot to profect my skills but get some errors.. well not errors really but the file size comes out to be in the 300mb range and no picture but sound. so now im interested in this mp4 codec. oh also i have adobe premier. what does anyone think about using that for converting movies and what not? prob the ppl that are taking video editing in school could come up with some good quality stuff. well hope this getting some answers......
