Keylight Hair Noise

The best way to remove noise from the edge of a keyed clip is to use the “Key Cleaner” filter. It is amazing but takes forever to do a RAM preview with.

[Tamer Aswad] “I have managed to pull a good key, but my only problem is with the noise I get on the edges”
Eliminating “noise on the edges” is what differentiates a good key from a bad one.
Sometimes it’s necessary to comp the output of multiple keyers together for the best results.

Hi Walter , yes that’s true, hence I asked what may be the source of my problem, it looks like it’s color sampling, as i use dslr cameras, which has 4:4:0 color sampling, I guess I have to invest in a a camcorder that records on 4:4:2

A better camera is never a bad thing. However, I’ve keyed plenty of DSLR footage with out any problems. A good light set up goes a long way.
For your situation use the Key Cleaner, last time I used it these settings worked best for me:
Additional Edge Radius: 1.6
Reduce Chatter: Checked
Alpha Contrast: 0%
Strength: 100%Stephen Smith
