@driftwood @LPowell I am trying to get the old @cbrandin 44/32/24 and 66 settings to work in GOP6. I do not have an understanding as you have of the secrets behind the encoder settings. I get pulsing where the encoder gets into backup mode (or what you call it). Can yu give a hint what to change/test?

@Tomaso, @ChrisPeters: Agreed. Manufacturers making up weird meaningless acronyms and jargon for modes instead of using simple, clear, technical specs is a big pet peeve of mine. Do they honestly think that the average consumer will be less scared of/confused by the term HBR than to simply call it what it is: 1080/25p or 1080/30p. Or what's with all this FSH, SH, FH, H nonsense... when it would be so much simpler and clearer to just designate actual resolution/frame rate/bit rate (such as 1080/60i 17Mbps, 720/60p 12Mbps, etc.)

Panasonic isn't the only offender here. Many of Canon's consumer and professional video cameras use a veritable alphabet soup to designate different bitrate/quality settings (MXP, FXP, XP+, SP, LP instead of 24, 17, 12, 7, 5 Mbps).

@Tomaso Thank you. I agree, strange name.

I recently purchased the coollcd HD2 monitor to use with the gh2 and hacked with 3.64 ptools. The problem I am having is that when the camera is set to NTSC tv out it works fine if I switch it to Pal tv out I can't get a signal to work on the monitor. I have tried plugging the gh2 into tv monitors and computer monitors and the two modes work fine. I have tried running a canon 60D through the coollcd monitor in both NTSC and Pal modes and it works fine. Is anyone else having similar issues?

@EOSHD In the article from Friday, 24 February, 2012 14:45 "Hacked GF2 – the $300 digital cinema camera " it's mentioned that you have succeded to use GOP 6 (6 frames between Keyframes). I have tested to do such settings for my GH2. I have based it on cbrandin 44 settings, but I can't figure out what I have to change not to get the encoder to fall into backup mode. could you disclose your settings pls

If I am less concerned about size of files, are "'I'-frame-only low GOP" patches the best for quality (resolution, motion) or do P frames (or B frames) help with motion to create a smoother flow from frame to frame? I'm slowly picking up the lingo and how things work within the system. Just trying to see how they affect practical results...

Basically If I don't care if the files are large and I already have good cards, are "I"-Frame patches the most suited towards best res and motion quality? or do other alternatives give better results for motion??

OH and one final question...

Would a constant Bitrate Patch work better in Lowlight? due to it not losing bitrate with the lack of detail? I love noir and nighttime shooting and trying to maximize motion and resolution in lowlight.

Just trying to make sense of what would work best Ive seen some great night video out of @bkmcwd. I have this lens (Panny Leica 25mm f1.4) and these videos like sold the deal for me to purchase it. I much prefer the bokeh of this over the Voigtlander and its sharper wide open.

For the record I started using Seaquake and then went to Quantum 9b, now am currently using Rocket V2 I'm mostly interested in 1080p24h. So thats where my questions are directed. @driftwood

Thanks!

If you install a hacked 1.1 firmware with Ptools 3.64, and then you want to go back to a 1.0 hack, like quantum 9b, do you install it with Ptools 3.63, or can you use the newest ptools? Is there anything special that you have to do, other than the usual firmware installation?

I am taking my GH2 underwater in a Nauticam housing with panny 14mm pancake, filming large moving subjects such as sharks, manta rays etc., can anyone recommend a suitable patch? Preferably HBR 25p, I will be using autofocus as the housing has no manual focus, but focus will be typically locked.

Anybody knows how to get rid of that greenish tone that often appears in gh2 images? Where does it come from? From my experience is has nothing to do with daylight or artificial light. It is more a thing of dark or black objects that you are filming...

@nic2011 Ok so its not the ptools - thats good. Yeah, youre going to have to trial IQ/Q (stay away for AQ just for now) get the basics working first. Also its IMPERATIVE you work out your Frame Limits properly (according to GOP and bitrate), or you'll always have problems.

Are there any hacks/patches that don't revert to 1080i when hdmi is plugged in? Makes it real hard to operate a jib arm without a monitor. Thanks...

A question for the experts: I always change some patches from Nick Driftwood + Chris Brandin because I want a longer GOP and bitrates around 50mb at 24p and 60p. The latter one is very important to me. So, what i´ve got now shows a very uneven cadence at StreamParser. Please take a look:

without movement + with quite heavy panning. At the panning shot the p-frames getting even bigger than the i-frames. Is this a really bad thing? The IQ looks Ok so far...

I have just launched Ptools and successfully installed v1.1 with increased bitrate.I want to try some other patches such as flow motion but i dont know how to download from the links. Im a mac user and they appear only as .png files. Im sure Im missing the obvious could somebody please point out the elephant to me.
