Letterbox Matte plug-in

[Lot Mallari]

We’ve been using this and it works great. The only problem we notice, is if we are cutting apple pro res material, then our sequence setting is the same as the clip settings. When we apply the matte to the sequence, it has green line. After rendering it, the matte disappear.

Please advise how do we solve the problem or any work around.

Thanks,

The issue is/was one of 10 bit vs 8 bit processing vagaries. Many moons ago I updated the code to fix this (in the free letterbox plugin that I hosted on my own webpage) but for anyone, like Lot and co, working from the code as originally posted here, the extra lines needed are/were:

UnMultiply (matteBars, kBlack);
Dest *= matteBars;

… pop those 2 lines in just before the last line and all should be well.
