GH2 DO NOT POST SEPARATE THREADS: GH2 Hack | Questions and Answers Thread

Question 1: Since I want to shoot with the hack for select "narrative" jobs but shoot stock for events where I shoots tons of footage, something like 12 hours a day last time I did one... What's the best way to have that flexiblility with the camera? Is it best to have two firmwares on two separate cards and then just update as necessary?

For an ordinary Panasonic SD card, or a Transcend Series 10, what patch/hack would be the upmost threshold it could handle? What would be the downsides to using a cheap card? Should I not even consider using old cards for hack and just use for event long shooting situations?



thanks

Is it likely a future hack can enable 1080 50p / 60p, or is this a GH2 hardware limitation? Thanks.

1. This is at the discretion of the person behind the camera. I can only say, try it out. Give it a test run. It can't hurt to have two firmwares on deck for any reason. I would advise you never rely on another forum member to make these kinds of calls, and you do some vigorous testing yourself if it's for events that may have some kind of monetary or sentimental value.
2. There are a lot of different hacks. Again, this is just up to person using the hack. Driftwood does have a patch out there that allows you to shoot at optimal settings for budget minded shooters using Transcend and other cards besides the Sandisk Extreme. The downside is like anything else that is cheap; it may not work as good as the more expensive cards. I personally will say, sure get a good brand and stick with it. I have two 16GB Sandisk Extreme III's and they work great. No hicccups on any of the death charts except when using a panasonic lens.

Probably not, but I wouldn't permanently rule it out. From what I've read, AVCHD 1 can't produce 1080 60p. And it's quite possible the hardware does have limitations. But, who knows. Many people said it wasn't possible to fly either.
 
Do any of the hacks affect the HDMI out on the GH2? I've gotten the impression that using the highest bitrate hacks and the fastest cards makes the HDMI output not really worth the effort. But I could be misreading that.

If you're referring to HDMI out when reviewing footage, then no, it's not affected. It's the same per usual. The bitrate hacks and and fast cards have made HDMI capture pretty moot since it has been seen by some as equal to, if not better than raw HDMI capture.

I purchased my Panasonic TM700 3MOS camcorder with 1080p60 @28mb/sec (AVCHD) in April 2010 long before AVCHD 2.0 came out.

Panasonic labeled the TM700's 1080p60 mode "MPEG-4 AVC/H.264" rather than "AVCHD". Granted, this is a self-imposed distinction in nomenclature, but Panasonic does make an effort to maintain technical consistency in the application of their brand names. AVCHD is strictly defined as a subset of the MPEG-4 AVC/H.264 family of encoders.
 
Help choosing a patch!

I will be hacking one of my GH2s next week. At this point it looks like there is somewhere in the range of 8 to 12 different patches available, all awesome. Would anyone care to distill it down to the basics? I would love to compile chart...

Hack Name - Bitrate - Details - More details - Ideal environment - Minimum card requirements

I don't mean to ask too much so feel free to reprimand me if you think this is unnecessary. I definitely plan on trying out some of the super high end hacks, but ultimately I think I will settle on something that doesn't eat up a 32gb card in 7 minutes...
 
At this point in time, I'd recommend downloading the new GH2 v1.1 firmware from Panasonic rather than installing a hacked version of the v1.0 firmware. Panasonic has made significant improvements in the functionality of the GH2 in the new firmware which you may want to check out. In the meantime, Vitaliy is hard at work on a new version of PTool for the v1.1 firmware which will supercede the current version and promises to be well worth waiting for.
 
Crash with CBrandin 44mb GOP12 AQ4

GH2 Crash with CBrandin 44mb GOP12 AQ4

This was the first time I've experienced a crash with this hack. I had been shooting all night with the camera, and after 13 minutes of recording a new clip, the camera automatically stopped recording. I pressed the playback button to see if it had captured the clip. It showed black and said it was unplayable. Uh oh. I started thumbing through the rest of the clips on the card. They all showed the same thing- black screen and 'unplayable' status. UH OH. Trying to remain calm, I switched the camera off, and turned it back on. Thankfully, I was able to see all (so I thought at the time) my previous clips and play them back, but not the last one that got stopped in the middle of recording. After bringing the card into my computer, I am actually able to see and play the clip that got interrupted. I also noticed something else- while the camera indicated I only had 78 clips on the card, I in fact have 102. Something must have happened during the crash that caused the camera to not only not see the clip that got interrupted, but a large chunk of other clips as well. I was shooting on a 32GB Sandisk Extreme Pro (95MB/s) card. I believe this is the fastest card they make. I was also shooting at high ISO (2500 I believe), and for this particular clip, I increased the shutter speed to around 100/125 as the lights on the stage I was shooting started to get brighter and started to blow out the image. For what it's worth, I also activated the AUTO LVF/LCD switch (sensitivity low) so I could quickly go from looking at the LCD to peaking in the LVF to check focus without pressing the button. I'm not sure if it had anything to do with it, but the crash seemed to occur at the exact moment I put my eye to the LVF, as it switched over from the LCD. However, I had been doing this all night without problem (I had already filled up another 32GB card)...

Also not sure if this has anything to do with it, but when I inserted this particular card into the camera to begin shooting (having just filled up the previous), the camera said 'Please insert SD card again' or something to that effect. I had never seen that before. So I did, and the camera seemed fine. Just to be safe, I formatted the card again before shooting. This is a brand new card, opened today. I inserted it into the camera once before, to format it, and then the second time it was inserted was when it gave me the error message, after which it seemed to work fine (though as I said I formatted it again, to be safe).

The crash occurred after at least an hour of recording on this card. I'm not sure what happened that could have caused the crash, but any insight would be most helpful. I don't want to be an alarmist, but it makes me a bit nervous to use the hack for event filming without being 100% confident in the reliability. Perhaps it was the card? Thanks for any and all info!!
 
I have found since getting into this whole GH1-GH2 world that listening to MR. Powell always works out well. He is the gold standard when it comes to advice here.
 
Hotconductor is totally right. It's time to have some sort of formal excel style doc that has version updates for old/new patches, patch modifications, running changes, basic patch info such as IQ/GOP/estimated recording duration, card requirements, etc.

The developers and Vitaly should approve a basic template that can quickly and easily be populated with new info. This excel file or PDF version of one should have a revision/summary tab of new patches or changes while the main "patch info tab" will contain the guts of the content.

This is a discussion that should probably be continued on PErsonal-view but the document should exist on both DVXUSER and PV. Whenever a new patch is added or modded, the file gets a quick update which overwrites the previous version and it should live as a stickied thread on DVXUSER and it's own thread on PV but the actual patch downloads must be done in PV.

DPs and Directors considering the GH2 aren't going to waste their time diving through hundreds of threads to find basic info. Even with the patch vault on PV it's still kind of a mess. Plus, the doc should have all the GH1 patch info as well.

In essence, this becomes a clear cut "menu" of patches. We want the GH2 to get the usage and recognition it deserves right? Keeping it easy to read and ingest will entice high end DPs greater accessability to the basics so they can pick and choose very quickly what patch best suites their productions needs.

The challenge is finding someone to upload and update on a regular basis. By the sounds of it hotconductor might be up for it. Hell, I'll even do it as long as I'm given the info. Let's just get all this organized properly. One more thing...if you haven't already donated...DO IT! These guys work their butts off giving us the hack privileges.
