Tip #1472: FCP: Problems Chroma-Keying HDR Media
This problem doesn’t have a workaround, yet.
Brandon brought this issue to my attention.
NOTE: This problem also occurs in FCP 10.5.1.
The source clip is 4K, 10-bit, HEVC HDR HLG.
When imported into FCP, and the Keyer filter is applied, what results is illustrated in the screen shot.
- The background is green.
- His shirt is blue.
- His face is Caucasian.
Sampling the green background, tweaking color selection and adjusting any other setting has no effect on the results. There seems to be no way for the system to separate green values from any other color.
I don’t have a workaround, yet. I’ve notified Apple and will let you know what I find out.
