It just stopped? No error? Or were you not looking at the screen when it stopped? What was the average bit rate of the recording? Have you tried a different card? I haven't had any problems in HBR mode with the settings. If anything, the problem with HBR 30p mode is that it is easy to make the camera lock up.

I don't have any 64-GB cards or any 45 MB/s cards, so I'm not sure if those are factors. My cards are 30 MB/s and 95 MB/s. The 95 MB/s cards are the fastest cards in the GH2, and I definitely recommend them if you are needing the highest reliability or are running into problems.

Try a different card. There are differences between cards that really matter (even cards of the same type), and can contribute to write failures and spanning failures. For that card, the only thing I can suggest is to use the SD Card Association SD Formatter utility with the format type option set to Full-erase or Full-overwrite. Do that two or three times. Yes, it actually makes a difference. My most used card, which had been used for literally thousands of test recordings, started giving me spanning failures, and this utility brought it back to life. One formatting wasn't enough - that only fixed the problem temporarily.

Otherwise, the only thing I would know how to do to is to lower the bit rate - something I'm not going to do given the quality constraints of HBR mode and the reliability I've observed so far in HBR mode.

The settings shouldn't affect autofocus behavior. I've never observed autofocus behaving differently.

@kazuo, I didn't set the pan correctly before exporting the video to Vimeo. Thanks!

@balazer, great, thank you. So it means no impact in motion, panning ... I use Cake now in both, GF2 and GH2. Thank you for your great work.

I am shooting with Cake 2.3b3 24L since a few days, doc stuff, everything looks great, very happy, thanks balazer

@balazer , I'm now testing Cake 2.3b, however I'm just curious why B‑frames are left out ? I'm not an expert in codecs, does this have any impact in motion, panning etc ? I like Cake :-)

Used Cake v2.2 and it worked flawlessly. I let the interview roll for over an hour with no issues spanning and in post I did literally next to nothing to match the GH2 and AF100 footage. Truly a piece of cake!

For the GH2s, Voigtlander 25mm f/.095 and LOMO OKC1-50-1 2/50mm lenses using 24H, Vibrant -2 -2 -1 -2, ISO 200 and K3200 for white balance.

The AF100, using Olympus 14-35 f/2.0 lens and a profile to match the GH2s as following (ISO 200, K3200):

1080/24P Detail Level -4 V Detail Level -1 Detail Corning -4 Chroma Level +2 Chroma Phase -3 Master Ped -5 DRS Off Gama Cine-Like D Matrix Fluo

The GH2 camera angles and her right side wasn't lit well, but it's a no budget on the fly production ;-)

I will investigate. I did notice a possible auto white balance issue around 1 minute. I'll need to remember not to use auto. Do you mean on the brown boxes as the kid steps away from them?

*It does look like there's some dithering on the boxes in the original file

this is my cake 2.3b3 test

I can't say anything about playback in Windows Media Player without knowing what DirectShow filters were in use. I use Media Player Classic Home Cinema, and its built-in filters work fine, as does ffdshow-tryouts.

Adventsam, Cake does not use B-frames.

Does cake 2.3b1 have b frames in 720p? Only I am sick and tired of 1080 with all that stutteryness, have tested extensively and I can truly see that much at normal viewing between 1080 and 720, only when I have my nose against the screen and the most demanding stuff. The 720p/50 is buttery smooth, can be thrown around and to cap it all the af works so effectively too.
