Bitrate 45 mbps mov vs. 17 mbps avchd?

Hi all,
GH2, 1920 x 1080, 17 Mbps, AVCHD
EOS600D (Rebel T3i) 1920 x 1080, 43 Mbps, MOV
Which one is better? or 17 Mbps AVCHD corresponds to which mbps MOV or vice versa?

Playing with AVCHD Upshift or with other convertors do really help?
Or maybe converting them to MXF??

What I really want is the highest bitrate that I can obtain?

Or Nano Flash really helps??

Can I get 50 Mbps / 4:2:2 footage with GH2 or Rebel T3i if I use Nano Flash??

Thanks in advance.

"What I really want is the highest bitrate that I can obtain?"

If you are talking about MPEG4 AVC only, then what you usually want is the LOWEST bitrate for no appreciable loss of quality. A faster bit rate than you need is only going to stress your system unnecessarily.

AVCHD is usually of the order of 16 Mbps for the video only or about 18 Mbps with audio and other stuff included. Blu-ray is usually higher.

If you source is 17 Mbps there is nothing to be gained by making it higher unless you are creating an intermediate file and wish to minimize loss of quality with multiple renders. However, you would be better off choosing a different coder for the intermediate file

If you are asking which will have better quality, the 45 Mbps MPEG4 AVC or the 17 Mbps MPEG4 AVC then off course if all else is equal then the 45 Mbps will be better. However, other things affect quality such as the lens, so the answer may not be that simple.

Post Script

I presume your MOV files are MPEG4 AVC, aka H.264. AVCHD certainly will be.

Hi,

by the way both file formats are MPEG-4 AVC/H.264.

The MOV filetype is just a container, and in the case of EOS files, the video part inside is encoded with MPEG-4 AVC/H.264.
