    Posted by Riccardo Sinti on May 16, 2014 at 4:59 pm

    I’m trying to import a matte clip to use instead of splines.
    Everytime i import an mov (8bit 256 greys) I get a dialog that says mov must be converted to 8bit grey scale to use as matte clip.
    When i go to clip module all i see is black.
    Any advice on using mate clips?

    First I tried prores out of AE6.
    Then I tried lossless 265 greys 8bit.
    I also tried a jpeg sequence.
    Mocha Pro always indicated that the clip would have to be converted to 8bit greyscale. There is a checkbox in the clip module to convert to 8bit so I checked that anyway.
    Nothing happens.
    I haven’t been able to find much more than a mention in the Mocha doc that you can import a matte clip to replace splines on a layer.
    I haven’t seen any tutorials that use matte clips.
    Anyone see any out there?
    Thanks!

    The key to importing an external matte clips is to create a mocha layer and make the shape cover the entire image area, then select the layer properties and insert a Matte Clip. mocha will read the matte and you will know it is working if you see the matte in the overlays.

    Hope this helps.

    Well, I wasn’t covering the entire image with a spline to make the layer, so I did that but still the matte clip does not show up after I import.
    When I go to the clip module the name of the matte I imported is in the drop down but when selected all I see is black.
    Is there a particular codec that is preferred?
    Is there a tutorial out there that utilizes this feature so I can see it in action?
    Thanks!

    Ok, I used an SGI sequence and it finally worked.
