Pulling mattes, footage with Noise
by Anthony Dupsta (dupsta) on Dec 12, 2007 at 8:59:56 am

I have a few HD shots that were scanned to Log DPX files. I have noticed noise in especially the blue channel.
I build my track mattes using keylight. During my key process I notice noise in the mattes. Should I denoise (remove grain) before I key? Also. Can you pull a better matte with the cineon conversion off?

I can't answer the question about Cineon conversion. However, I do know that it's possible to pull a seemingly-good key using Keylight that results in noise within the keyed subject.

Here's a thread that desribes what I do in those instances:
