    Thanks for writing in and sharing the screenshots. I don't see the banding in the Ae project file unless I zoom in and look for it. I exported the file as MOV and I can see a bit of banding in the Quick Time player and was fixable by applying the Noise effect with the Amount of Noise set to 1%.

    Let us know if that works for you. I am moving this thread from Bugs to Discussions for now.

     

    Thanks,

    Nishu

    I am not sure I understand what you are saying.
    I am saying that AVI export increases banding.
    Uncompressed MOV does not cause banding.
    The reason you see banding in the original image is because of the 8 bpc gradient.
    AVI export clearly increases the banding more than that.
    This problem does not seem to occur with CPU processing, which makes it seem more like a bug.

    I'm not talking about not using AVI or anything like that, I'm saying that as long as this phenomenon occurs only with AVI, it is a bug.
    The MOV format does not cause banding beyond that caused by the gradient, and there is no error when the difference is taken from the TIF.
    Only when the AVI format is used, an error occurs in the difference from the TIF, so this is a bug no matter how you look at it.


    It's not a bug. It's a problem with a format developed in 1993 that has limitations that were never addressed.
