    Tor,

    Sorry I've been sidetracked by piddlin' with HDV.

    Thanks for the suggested white balance suggestions.

    I started with your suggestions for white balance and did a little tweaking with the color balance filter in addition. Next, I rendered that out to a new track and copied it. Then I used the soft light blend mode and a mix level rubberband to sum the 2 new tracks together which really improved the apparent gamma. I also experimented with some additional blend modes, but settled on the soft light.

    The footage is now totally usable! EDIUS is really powerful once you learn the tool nuances.

    Regards,

    Tom

    I think it's more than just a green cast. I dropped the footage into Edius and applied the White Balance filter, and got relatively pleasing results with the following settings:

    Black Balance:
    Cb: 5.0, Cr: 1.0

    Gray Balance:
    Cb: 30.0, Cr: 0.0

    White Balance:
    Cb: 27.0, Cr: 1.0

    Adding the Media filter at 30 to reduce noise will improve things further.

    Using the White Balance filter have you tried using it in Manual mode clicking on the Black, gray and white buttons, probably a silly suggestion.
    The Image looks to be well within the range of the WB filter but I doubt is the colour can be restored, the Saturation slider may help.
    I am probably just going over what you have already done
    Regards Barry

    Correcting Footage with Severe Green Cast

    I have some old VHS footage I'm trying to salvage for someone, and have kind of run into a brick wall trying to get rid of a severe greenish cast over everything.

    It looks like it was shot in very low light, with flourescent ceiling lights. Plus, it's a poor dub of a 20 year old dub.

    I've tried various combinations of white balance and the color wheel with very limited success in Edius. I've had marginally better success in Vegas using a combination of filters, but not enough to warrant the time that would be needed to render.

    Can anyone suggest a method of getting rid of severe color casts in Edius? I've done pretty well before with color correction, but this one particular video is giving me fits.

    Se attached still image.

    Thanks!

    Tom
