This is the next comparison of the videos created simultaneously on a camcorder using its own AVCHD 108060p (28Mbps) compression and from its HDMI output using the Ninja 2 and Apple Pro Res 422 (145Mbps). This time both videos were color graded in Vegas Pro using the 'Warm" preset from Magic Bullet Looks and then both were rendered using AVCHD 108060i at 22 Mbps.
The original video here is the camcorder produced AVCHD 108060p 28Mbps file.
The color-graded original Apple Pro Res 422 video is here:
The question is whether the color grading and recompression degrades quality differentially across the two original streams.
