    Default DVD unwarp anamorphic Picture - minimal loss of quality

    Hallo, hope my english is well enough so you are able to get my intention.

    Well, i just begun makin my first steps in video-editing... even though i know very little until now i like it... its something like meditation for me.. ...

    The past two weeks i worked on reencodes of DVD. For this i put them uncompressed on my harddisk merged the VOBs, extracted the MPG-Stream and reencoded it with VIRTUALDUB or TMPGEnc XPRESS as MPEG4 (XVID)...

    Now i realized that the picture quality is not as good as the former original mpeg2-stream from the DVD. I am wondering how this can be.
    My intention was to make a nearly 1:1 reencode because i dont like these tiny DVDRips...
    i want the original shown resolution in the player (e.g. 1024x576 or less height if the ratio is not 16:9 or less widht if the ratio isnt widescreen).. (e.g. i reencoded The Lord of the Rings. Now it is unwarped and has a resolution of 1024x430 pixel)
    i already know that widescreen dvd-picture is anamorphic... so... i just put a resize filter on it cropped the black borders and START... so far so good... most videos look very nice.. iused unrestricted profile at 8000 kbps... but yesterday while watching u new encoded one i saw something like stairs on a thin line... for comparism i started the original and NO stairs... now my questions are...

    should i prefer another codec for better quality results?...
    8000kbps is pretty much and make the new streams bigger than the original, but i thought more bitrate means keeping quality..am i right?...

    Perhaps this is a new-be-problem... perhaps it is not... hope you can help me.

    It sounds like you have interlace artifacts. Try changing the field properties, upper field first or lower field first which ever works best. Some times when watching an interlaced video on a computer monitor, as they are designed to show progressive pictures, it looks poor but once it is burned on to a DVD and played on a normal TV it looks ok.

    If you don't understand what I'm saying try researching interlace in your native language.

    No it's ok... i understand the difference... thank u for answering

    and what about my other question... are 8000 kbps for 1024x576 res. too much?
