1MB=8Mb...so multiply those numbers by 8. I believe that's what Nomad was saying.

When I transfer the footage with Log and Transfer in Final Cut 7, it says the bit rate of the clips is around 13-16 MB/s for a 24H clip. Is this what I should be aiming for?

You don't need to aim for any particular bitrate - the GH2 will automatically use only as much bitrate as needed to record at the quality level that Flow Motion v2 is designed to deliver. As others have pointed out, 13-15 MegaBYTES/sec = 104-120 MegaBITS/sec, which is the highest bitrate FM2 can deliver in 1080p 24H video mode.

Flowmotion V1, I'll testing new patch this weekend ;-)

Is there a shorter GOP setting for Flowmotion in 720p PAL mode? I am shooting kids sport and for the most part Flowmotion 2.02 is very good. However on very fast motion there is a muddy look to the fast moving parts of the image which is not surprising considering that each frame is very different. So my question is, is there a stable 3 GOP setting or lower, or was this jettisoned because of stability issues.

Thanks in advance

tested on 24H with Instantaneous Death Screen, but fails, it writes with more than 126Mbits after that i get speed problem card, and my card can go max 130Mbits without crashing.....on 24L everything is fine

Can FM2.02 for 24H mode be somehow limited to not to go over 100Mbits?

@omnidecay

i have TRANSCEND 64GB class10, test results: READ: 163.8 Mbps WRITE: 126.9 Mbps

It is not fast as SanDisk, but it is still one of the fast cards out there.

Is there a shorter GOP setting for Flowmotion in 720p PAL mode?

Good question. During the development of Flow Motion v2, I tested a variety of 720p patches using both 3-frame and 6-frame GOP's. One of the inherent complications in optimizing 720p modes is that they share several bitrate settings with the 1080p HBR/FSH modes. In order to achieve reliable operation with a 3-frame 720p GOP, I had to tweak it in a manner that produced sub-optimal results in 1080p HBR modes. Using a 6-frame 720p GOP allowed me to optimize both 1080p and 720p modes to operate reliably at 100Mbps peak bitrates.

720p / SH Lumix 7-14 and not compatible with Flowmotion v2.2 :(

@LPowell Thanks for the reply. That makes sense as this patch is incredibly reliable. It also is as smooth as butter in FCPX in AVCHD mode which hasn't been the case with other patches which I have had to transcode to Pro Res. It's also very economical card wise.

I would still like a shorter GOP for 720p, so what are my options? Am I able to cannibalise this as I really just want to stick with 720p.

@kurt10 transcode with 5DtoRGB. The rain is in the libraries licensed by Adobe, it's not a patch issue. Non-patched GH2 footage does it just as bad in CS6 under similar shooting conditions as when it shows up in patched footage.

In my experience, 5DtoRGB transcoded footage, filtered and read as ProRes looks better in and rendered out of CS6 than if you rely on CS6 reading the MTS files in any case so, rain or shine, it's not a bad habit to get into.

@BurnetRhoades I've migrated to CS6 and had my first experience of the rain in FlowMotion footage. I guess I'll be transcoding to ProRes from now on. Aside from the alleged improved gradability, I've read it's supposed to scrub better than AVCHD too. Transcoding my current project is going to take up 800 gig of data so lots of storage is a priority if you'll be working on a few projects continuously.
