Keying with the EX1
by Terry Griffey (griffeyt53) on Feb 18, 2008 at 3:40:21 am

Still trying to get up to speed with my new EX1. Working with chroma keying now with a key, fill, and highlight. Flat and evenly lit green screen with subject 8 feet from screen. Camera distance to subject is 10 feet. Waveform monitor shows luma from 75 to 95 on subject and 30 to 40 on the green screen. Video is HQ 1080/30P imported into FCP 6.0.2 via XDCAM Transfer. FCP sequence timeline is 1920 x 1080 HDTV 16:9 with a compressor setting of XDCAM EX 1080p30/35 Mb/s VBR.

Current experiments show best results using the Nattress 4:2:0 chroma sharpening filter with the "smooth then sharpen" setting before using the FCP chroma key filtering. The unfiltered image shows excellent detail and want to preserve as much as possible when chroma keying.

Suggestions?

Thanks!
