    Hi, can anyone help this newbie to video comptression.
    I have an AVI which is 666MB in size.
    The problem with the Vid is it has a green boarder on the edge.
    I download VDUB and removed the boarder, but whwn I re-save the AVI it jumps upto 15 gig.

    I have tried all the normal routes by D/Ling MSU screen capture and setting the keyframes to 150 but it stiil makes my AVI 15GB.
    Can anyone tell me what iam doing wrong

    Thanks

    The video has to be reencoded because you changed the size,
    but you forget to set the video codec, so it's writing uncompressed
    frames.

    Select video/compression and choose xvid or divx, select configure,
    check the settings (perhaps set the bitrate ?) OK out, and
    file/save avi.

    Hi There, thanks for a quick response.
    I used the Codec MSU screen capture then saved as AVI.

    I have just tried using the DIVX codec but I get an error telling me the video frame size may not be compatable with this codec.
    my frame size is 720x480 no of frames is 679. I looked at the setting but there is no frame size showing this size wothin the divx codec. Do I have to adjust the fram esize in Vdub? if so how do i do that? or do i have to download a different codec? the DIVX codec i am using is DIVX 5.21 codec.
    The video is old standard eight films put onto avi
    Thanks for your help

    720*480 should be fine.
    How did you get rid of the green edges? Did it alter the size?

    Try setting the encoder back to defaults. The encoder is probably
    the width and height to be multiple of 4.

    I used the filter null transform and cropped the green boarder.

    Tried resetting to defaults still got the same. I am going to save as AVI without thre green boarders and then try to compress the 15gig file with the help you have given me

    Thanks again
