    Hi, I was wondering if anyone knew how to maintain the original 16:9 aspect ratio of an XviD or DivX video when converting to DVD.

    I've read the "Convert a DivX or XviD AVI to DVD guide, and also searched everywhere on the forums, but haven't been able to find an answer.


    I know alot of people have to be wondering about this.

    what you see/download whatever, is usually use 1:1 ratio.

    if i want to encode for tv viewing, 640x480 a 4:4 source. i'll encode it to 720x480 by resizing it. 720x480 is also the legal and standard res.

    so for 16:9 use the ratio and calculate it. make the width 720 first then find the correct height. and the add borders ass necessary to get the 480 mark.

    and also don't forget to put the 16:9 tag.

    unless the xvid video is already encoded anamorphically.
    all you need to fo is use the 16:9 tag.
    usually when encoding anamorphically, only cropping is used, unless you're a newbie...
    so just add borders as necessary.

    try searching for anamorphic 16:9

    ".... unless you are a newbie"
    ok Mr professional, why don't you explain more???
    How can we add borders to keep the aspect ratio correct?

    There is a new software that converts Divx and avi files to DVD compliant ready for burning. I've tried it and it's great. You can choose the aspect ratio. Best of all it's free in the current version:-

    TMPGenc let you also choose the aspect ratio. But, the previosuly ripped DIVX or XVID is usally shrunk to a lower resolution (a non DVD compliant)
    So when it is converted back to a DVD compliant aspect ratio (wether 4:3 or 16:9) you still get a stretched movie.

    If you use AviSynth to frameserve to your encoder you can use it to make resolution changes and add borders. A script like this would do what you need:

    # Replace V with the correct vertical resolution
    # Replace T with number of lines to add to the top
    # Replace B with the number of lines to add to the bottom
    AviSource("c:\wherever\filename.avi")
    LanczosResize(720,V)
    AddBorders(0,T,0,B)
