    NTSC DV to H264 MP4: Vegas renders wrong aspect ratio

    Hi,

    I am trying to edit my old family videos.
    My aim is to produce updated and compact videos, playable on the Media PC and modern display devices (LCD, Plasma, etc).
    When I play the rendered videos they show in the wrong aspect ratio.

    The source videos were captured to AVI files as NTSC DV - interlaced, 720x480 pixels, 0.9091 PAR, and 3x4 display aspect ratio.
    I am rendering the edited videos to MP4 files as AVC H264 - progressive, 720x480 pixels, 0.9091 PAR.

    To play the videos I use MS Media Player, GOM Player, KMPlayer, and more - all show the wrong aspect ratio - 3:2 instead of 4:3.

    I use the 'Vegas Movie Studio HD 10' to edit and render videos.
    I have tested a great deal of combinations of project settings, stream properties and render settings. But the videos are still rendered as 3:2.
    I also checked out Vegas for SAR settings, but found none.

    After a week of consultation and research I am still baffled-
    Is there no support for non-square pixel ratio with H264 or MP4?
    Does the problem lie in the latest Vegas Movie Studio I am evaluating?
    Is this a gimmick to push me to buy the Pro version?
    Or maybe I still did not get the right configuration/setting for rendering such a video?

    If you know of the correct settings to render the videos properly then please elaborate.
    BUT - I wish to avoid resizing the video frame itself. I much prefer setting the SAR/PAR/DAR properties.


    Thanks
Working...
