GH2: big loss of bitrate after 3.64 update

[luminescence]

Newbie here again. Followed all the instructions for updating firmware 1.1 and 3.64 to the letter. Then I shot some cinema 24H footage which all looked fine but showed 11 mbps - instead of 44 mbps in the 3.64 update checked box. (Did not check any other boxes) So instead of doubling my bitrate, it was halved.

I tried several times with different exposures and lenses, same result. So then I did a clean reinstall of firmware 1.0, same problem, likewise with firmware 1.11 and finally back to 3.64 with one check box marked against AVCHD for increase bit rate to 44. I went carefully through the entire process twice with all the firmwares, uninstalling and reinstalling so cannot figure out what happened.

I note that both 24H and 24L in cinema mode came out the same - 10-11 mbps. (Should be respectively 24 and 17 according to the manual.) On the last try after the second reinstall I got 15 mbps on cinema 24H and 12 mbps on HBR mode. The camera is a week old, working fine, the footage looks OK, so is there something I am missing with the camera settings?

I noted in another post somewhere here (cannot find it now) that someone else had a similar problem but managed to retrieve the bitrate after reverting to firmware 1.0. I am not sure if they did that working with V1.0 and 3.64 or just reverted to the factory settings of V1.0.

What should I do?

fixed this problem, I did not change the bitrate in the ptool program to 42, duh! sorry to waste anyone's time. I realise this is not down to EOSHD so am posting a suggestion on Ptools -  for software challenged people like me, we need to have it spelt out for us in some instructions, as those who write these things take what is obvious for them, for granted. So, one step of the instructions could read something like,

"If you check the AVCHD 24H box, don't forget to enter the bitrate value (42 etc) before you save."

Thanks for your post.

I am also a newbie. My question is where do you find firmware 1.11? All links I have found point to the old 1.1

Thanks, rjett

1.11 and 1.1 are the same. Just the labelling varies.
