    Alpha Cropping in 8.10.0 (Potential Bug)

    Hi there,

    I am running Avid Media Composer 8.10.0 on my late 2009 Mac Pro.  And with this latest Media Composer update I noticed that there is what I perceive as a bug with clips containing alphas when they are cropped in Avid.  I did not experience this in the previous version.  

    I have a lower third that is a keyable tif file, and I wanted to crop the bottom portion of the lower third to cut off part of the the title (that has the alpha channel), and when I use the crop function (cropping from the bottom) in the effect mode, it messes with the luminosity of the alpha, and blurs the title.

    As a workaround for now, I'm going to crop out what I need cropped out in After Effects, and then re-import, so I don't need to use Avid's crop function.

    Avid team, could you have a look at this?

    Thanks so much!
