@driftwood superb sir,....

@sohus I have used the 64GB Transcend SDXC card you mentioned. It is nice to have the extra capacity but I tend to mainly use it with less demanding settings - it often struggles to keep up with demanding GOP1, ones. Still, in a pinch I used it for that purpose when the detail of the scene was low enough.

By the way, to anyone that has not tried the basics for improving reliability (and some of the comments above reminded me that it is not universally done) here are some things that may help your card cope. Some repeats included.

• Shoot in Creative Mode with exposure mode set to M.
• Use manual focus mode.
• Use a manual focus lens (no electronic communication with the GH2 can help).
• Set your film mode to -2, -2, -2, -2. If you want to mess with saturation, feel free, but upping the sharpness can decrease stability if you are on the edge of working.
• Intelligent Dynamic and Intelligent Resolution off.
• No AUTO ISO. The camera is also doing less processing at lower ISOs (at least based on limited stability trials late last year, but they were not strictly controlled in my case).
• Shutter speed can affect stability, so if you tried everything above, you may want to try modifying the shutter speed as well.

This is not really a "tip" in the same way as the above, but you can improve stability by under or overexposing the image in a pinch. Sometimes that can be enough to make a given setting fit into the datarate a lslower card can handle.

And of course, softer lenses and shallow DOF tend to reduce the amount of data being recorded, so sometimes that can help, too.

But most of these extra comments are extreme workarounds, while the rest of the list is more practical.

@SisterCities ;-) LOL And my fav line from this pre-Spinal Tap brilliance...

Guitarist Vim: "I could play 'Stairway To Heaven' when I was twelve. Jimmy Page didn't actually write it until he was twenty-two. I think that says quite a lot."

Classic Bad News.

@Frame Did you copy over the contents of the sd card to your hard disk first? SDcard are notorious for not working correctly on import - especially spanned files/4Gb max files. Premiere Pro handles them flawlessly. Just drag and drop the entire Private folder (from hard disk copy) into your bin.

@driftwood , can you make a separate thread about Cluster settings only ? :-)

@frame, tsmuxer works well. http://www.videohelp.com/tools/tsMuxeR

@driftwood "Yeah, you didn't let the dog in free, did you?"

@LPowell, @driftwood - I've had the gh2 for nearly 4 months now and have been shooting various things with all your settings, or at least most of them. It's my first digital camera. Before it was always film. I can say that there has not been one real problem with any of the settings, when I have done my job correctly behind the camera. Compared to the magnitude of some of the 35/16mm screw ups I have been a part of, there is nothing wrong here. Recently, a chap posted a beautiful narrative clip of a tense guy and a ballet dancer, that was shot with the gh2 and flo mo or cluster, and wowza! there's the proof. He was doing his part by getting the contrast ratio right, moving ahead beyond whatever little problems get in the way. What a relief this is - Not at a dollar per second as with 16mm... $5 in 35mm. I am amazed how great this little camera is, when used with care. I've used the red epic, red one, alexa and a few other rentals, but this little camera with vitaly's hack and your creativity is the wind of change. It's really fun to be part of. So thanks eh!

Cluster V4 6gop variation, I cover a 20 minutes dance performance with a 16gb Sandisck extreme pro. No problem at all. Very bad lighting condition at the place, at 1600 iso, very pleasent fine noise. This will be part of an interview I will shoot with the dancers, I will post it when is done.

@Zaven13 After reading reports of failures in Flow Motion's 720p60 SH mode when using auto-exposure features, I did more testing on the consumer-friendly automated options of the camera. My hunch is that virtually all of the v2.02 stability issues in 720p60 SH mode are related to the use of any combination of the following options:

• iA auto-everything mode

• Creative Movie Mode in P, A, or S exposure modes

• iDynamic exposure modes

• i.R "Intelligent Resolution" modes

As you mentioned, Flow Motion v2.02 already provides a way to make reliable use of these convenient auto-exposure features in 720p mode - the 60Mbps H mode (and the 1080i FH mode as well). If you have time, I'm wondering if you could try to confirm how reliable 720p60 SH mode is in manual exposure mode with all of the above features turned off?

Good points @Zaven13

@driftwood If you need anything else let me know. My mistake, but alright I'll give it a shot. Would using something other than SH under 720 60p give me better results?

This will be the third different setting ive loaded onto my GH2 trying to film fast motion bmx at 720 60p. V4 and V5 have both given me write errors.

@driftwood It says the max GOP size was 20,084,160 Bytes. Not sure if thats what you're asking for. When i look at the GOP .Frame column it seems that the recording was stopped when it reached the number 24.14. I have it in front of me if you need anything else. I didn't try 24p, i just put it on H rather than SH and recording was just fine.

Which patch would you recommend for the best quality 720 60p recordings that will be stable on the sandisk 30Mb/s card in high detail?
