So, what is the IBK keyer? The very non-technical answer to that is that the ‘image- based keyer’ is a proprietary keyer in Nuke that typically deals with classic bluescreen or greenscreen plates (that need keying) by recognizing that these plates do not always have uniform color coverage. We’ve all seen uneven blue and greenscreens; that’s one place where the IBK Keyer can come in handy.
