    Hi,

    I have a DVD that I made from a 720x576 mpeg but I need to re edit some of it and deleted the original source file. I have used ImTooDVDRipper and played around with the settings as well as another program which i forget the name of but both times the resulting avi file is much lower quality than the DVD footage. Does anyone know any settings or different bits of software that I can look at to rip with no compression at all so I can re edit the footage in the highest possible quality?
    Thanks

    You can either

    1. Edit with a dedicated mpeg editor - Womble Mpeg Wizard or VideoRedo are both good - which will only re-encode the open GOPs or changed sections (e.g. if you add a fade etc) but leave the rest untouched

    or

    2. Convert the mpeg to a lossless format such as huffy or lagarith by using virtualdubmpeg-2 in Fast Recompress Mode. However this is only lossless until you re-encode the entire clip after the edits are done, at which time there will be some change to quality, although how noticeable is hard to say.

    NB. Option 2 requires a lot of HDD space - 30 - 40 GB per hour of footage.

    thanks for the prompt reply.. with option 1 will that actually get the files from DVD to an editable format? I really need to edit using premiere pro as I have some specific things that I only know how to do using that software. I take it that Womble Mpeg Wizard or VideoRedo are mpeg editing tools and not dvd ripping tools?

    Yes, they are editors. If you want to go down the Premiere Pro route then you will have to re-encode the entire video.

    If this is a commercial DVD, rip it to your HDD with DVDFab HD Decrypter, the use VOB2MPG to extract the mpeg program stream out for editing. If it is not a protected disc, just use VOB2MPG directly.

    Personally, I would still convert to Huffyuv or Lagarith, then open it in Premiere. You can open the mpg directly in PP, but I think you will find it more responsive if you work with one of the other formats.

    ok im slowly understanding.. its not a protected disc as I made the DVD. I'm downloading VOB2MPG now so I can use that to extract the data and convert to an mpeg? Will that be lossless quality?

    What program would I use to convert to Huffyuv or Lagarith? What would the resulting files extension be? still mpg?

    Many thanks

    VOB2MPG just extracts the video/audio from the VOB, it doesn't re-encode, so there is no quality change.

    Huffyuv or Lagarith are generally stored in the AVI container, so the extension will be .avi. You can use Virtualdubmpeg-2 in Fast Recompress Mode to convert it to Huffyuv or Lagarith. Make sure you have space though. 2 hours of full-D1 video is around 60GB using Lagarith, a little more using Huffyuv.

    ok great i will use virtualdubmpeg-2.. I am new to this but used it yesterday, I assume I apply a compression filter and select the huffyuv codec and then push f7 and name the output file?
