Now that we have talked with the camera person he is of the opinion that shooting XAVC S is higher quality than shooting AVCHD. I found the specs below and I'm not sure I see a clear indication that XAVC S yields a better image. I see in the Image Size specs that the Mbps seem to be higher with the XAVC S.
XAVC S HD: 1920 x 1080 (60p/50 Mbps, 30p/50 Mbps, 24p/50 Mbps)
compared to
AVCHD: 1920 x 1080 (60p/28 Mbps/PS, 60i/24 Mbps/FX, 60i/17 Mbps/FH, 24p/24 Mbps/FX, 24p/17 Mbps/FH)
and
MP4: 1920 x 1080 (60p/28 Mbps, 30p/16 Mbps)
I've read on the L2 that data rate isn't always a clear indicator of image quality as the type of compression and it's efficiency play a part so a lower data rate can be deceptive.
Can any of our more production savvy folks confirm of deny or explain if shooting XAVC S on the Sony a7RII is better quality than shooting AVCHD or MP4? Our camera person is convinced that shooting XAVC S yields better quality even if it means we have to transcode to make it work in Avid. Any insight would be appreciated.
