  • Creating an Alpha Matte for Resolve

    Posted by Craig Harris on November 26, 2010 at 7:24 am

    I have to create a 16:9 matte with a 4:3 box cut out in the middle. I was wondering if anyone could help me out with a tutorial or any ideas?
    I understand how to add a matte in Resolve… it’s Photoshop I’m not great with.

    Any help would be much appreciated!

    Start by adding a new layer.
    Use Marquee, and in the upper part of Photoshop, select Style: Fixed Ratio. Set Width: 16 Height 9.
    Now, click and drag until you’re happy with the size. Fill it with black.
    Select all (cmd+a) and use the Move tool, and center it in X and Y.
    Deselect the selection.
    CMD+click the layer so you select your 16:9 of black. Make a New Layer.
    Invert selection and fill this with black. Delete the previous layer.

    The same goes for 4:3.. activate the Marquee tool, set 4:3.. and so on.

    Thanks!
    I understand how to do that part but am not sure how to carry it over to DaVinci with transparency.

    Would I save it as a TIFF and then convert it to a DPX?
