69. How does this compression compare to the native Sony EX1/EX3 CODEC?
Compare the two images below, the left image is from the native XDCam EX is 4:2:0 at 35
Mbps, while the right image was recorded on the nanoFlash (via the HD-SDI out of the
EX1) using the XDCAM 422 at 100 Mbps. Note this is an extreme pan and rotation test
and not indicative of the normal quality from the EX1.

35 Mbps 4:2:0 vs 100 Mbps 4:2:2
70. How does MPEG2 compare to DVCProHD?
DVCPro HD is an Intraframe only codec with a maximum bit-rate of 100 Mbps.
DVCProHD resizes the video from 1920x1080 to 1440x1080 (50Hz) / 1280x1080 (60Hz)
and then compresses the image. Our MPEG2 CODEC maintains the full-raster of
1920x1080 and produces superior image resolution.
