    Posted by Terry Nahirny on November 20, 2007 at 11:33 pm

    Can anyone help me get rid of the black bars on the side of my mpeg 2 renders?
    Is vegas putting the video out of proportion when it does this?

    tks,

    What is your footage? What is your project settings? What is your rendering settings? Vegas doesn’t add black bars to the side of your video unless you “ask it to”.

    Footage:
    HDV 60i

    Vegas Project Properties:
    HDV 1080-60i (1440×1080, 29.970 fps)
    1.3333 (HDV 1080)
    32-bit float, 2.222 (Video- gamma)

    Rendering:
    MainConcept MPEG-2
    DVD Architect NTSC Widescreen video stream

    Should I have “Stretch video to fill output frame size…” selected?

    tks, t

    No, you should not have stretch on. There is a small difference in the aspect ratio of HDV and DVD, which is why you are seeing this. There are no black borders in the finished result.

    So you are saying that everyone’s DVD’s that start with HDV footage ends up smaller, width wise?
    I’m not sure I like that.
    It seems to me when I play the HDV version next to the SD render, that the SD picture has been squished in (people look a bit skinnier-no one seems to mind this issue but me :).
    I just don’t think this should be happening. I want my proportions to be accurate.
    Is there something else I could be missing?
    I’ve captured the footage with 3 different apps with no change in final render outcome.
    Anything else come to mind?

    The image is not squished. It is just the way things are, and like it or not, it has to be like that due to the difference between HDV and 16×9 DV footage.

    (people look a bit skinnier-no one seems to mind this issue but me :). … I just don’t think this should be happening. I want my proportions to be accurate.

    People don’t look skinnier. This scaling has to happen, and your proportions are still accurate. This is just the tiny difference between HDV and DVD aspect. Again, nothing happens to you video, it is not getting squished.

    I’ve captured the footage with 3 different apps with no change in final render outcome.

    Again, this is in the nature of rendering HDV to DVD Widescreen. They all “do it” because it is the correct thing to do? Or, to put it differently, they are not doing anything at all, they are scaling your video down from HDV to DVD as accurately as is possible.

    [TerryAdrian] “1.3333 (HDV 1080)”

    Change that to 1.34 pixel ratio. or 1.3340 – that seems to resolve the math…

    Tks Ramond, I’ll give it a shot.
    Will this put the video a bit out of proportion though?

    No, not at all.
