I think the system VariCam HD avc-intra 100 is second only to the CineAlta HDCAM SR 4:4:4 in f-23 f-35 and the new frw-900 (I think this is the model)
The signal from the AVC-intra 100 4:2:2 features a 10 bit image simply remembering that wonderful HDCAM SR 4:4:4 is also 10 bit I believe that passing the image of the AVC-intra by color or after and you get images perhaps even better than the HDCAM — SR.
The XDCAM — EX and XDCAM — HD lose feio pra avc-intra and that to compete com the XDCAM — EX a Panasonic launched its AVCCAM that according com they hit any codec based on MPEG-2 longgop.
I think the take the CineAlta VariCam facinho. But both are exelentes CineAlta cameras and respond better in environments less enlightened.
