I hope to be getting a GH2 soon and I've seen great progress and amazing results from 1080p @ 24p. However, since I use a lot of 60p @ 720p for slow motion shots I was wondering if there are any good patches that will achieve the amazing results of 1080p for the 720p slow motion? Ideally I'd like a high bit rate which produces really nice sharp slow motion, the kind of sharp image you get from 1080p.

Therefore are there any good patches for 720p at 60p? If there isn't any patches could I possibly change the bitrate and GOP myself and still achieve better 720p than the stock firmware? I will be using a Sandisk Extreme Pro 95MB/s.

The body had original firmware v1.0; I tried to install the hack firmware several times but the camera never detect the hacked firmware on the SD card after "play" button was pushed (thus, did not give me the option to update).
I decided to install Panasonic's newest (12/7/11) firmware v1.1.
As expected, my GH-2 detects Panasonic v1.1 firmware immediately and updated successfully, first try.
After playing around with Pana v1.1 firmware for few minutes, I decided to go back and install the hacked firmware that I could not do before.
To my surprise, it worked! So now I have v1.0 (hacked) on my GH-2.
Thank you.

I shot this video at the end of July with a GH13 and a Red Mx. All of the body mounted shots that you see of the artist running around in were done with the GH13.

The concept of the video was inspired by graphic novels, and a bleeding of reality with dynamic illustrations. As a result I attempted to give the footage an HDR, almost drawn-in look. Enjoy!

I will simply outline my findings, so that you can create your own patch settings to suit your needs:

* Increasing the overall bitrate will decrease reliability while doing nothing to improve video quality or increase the recorded bit rate. Just leave it at the default 18 Mbps.
* SH and H modes are equivalent. Feel free to program them with different bit rates and switch between them.
* The GH1 codec accumulates errors over the length of the GOP. Thus you need to keep the GOP somewhat short, under 12 frames or so, to keep the errors from becoming visible. Shortening the GOP increases the recorded bit rate and decreases reliability. I settled on 10 frames.
* Using a GOP 10 frames long: no failures with the bit rate set below 27 Mbps; failures were produced with great difficulty at 27 Mbps; failures occurred infrequently at 30 Mbps, and easily at 33 Mbps. I settled on SH=27 and H=25.
* No differences in reliability were observed between a Transcend class-6 card, a SanDisk Extreme HD Video UHS 30 MB/sec card, and a SanDisk Extreme 30 MB/s Edition card. It would seem that the bottleneck is not the card, even though failures are shown with a card write failure message.
* Changing the overall bitrate 2 or video buffer size produced no change in reliability, recorded bit rate, or video quality.

On the GH1, 720p remains my favorite shooting mode due to this camera's lack of 30 fps in 1080p, and because there is much less jello effect in 720p.]]> https://personal-view.com/talks/discussion/1110/idynamic-range-possible-to-hack Wed, 05 Oct 2011 17:20:55 +0000 Matt 1110@/talks/discussions
Do you reckon that it might be possible to change the threshold of the iDynamic setting, or perhaps enable some kind of manual settings (an "always on" thing would be sufficient in my book), to give the shooter more control, and stop it from requiring fair underexposure to activate it?

I've attached two pictures that REALLY show what iDynamic is capable of, and how many creative and technical opportunities it opens. Unfortunately, I wanted the interior to be brighter, but when I increased the exposure, iDynamic decided that it didn't have to do its job anymore, and turned off. :\]]> https://personal-view.com/talks/discussion/1388/shooting-olive-trees-documentary Tue, 08 Nov 2011 05:44:54 +0000 oneday 1388@/talks/discussions

https://www.personal-view.com/faqs/gh2-hack/ptool-software

GH2:
- Improved bitrate patches
- Improved GOP patches.
- Improved MJPEG size patches.
- Added quantizer patches.
- Added few other encoder related patches.
- Few fixes, including 24L behaviour.

---

1. You'll need this base firmware:
http://www.personal-view.com/talks/discussion/330/new-gh2-firmware-leak

2. StreamParser by Chris Brandin as help tool to analyse AVCHD streams -
https://www.personal-view.com/faqs/gh2-hack/ptool-software

Other good idea is also use trial version of Elecard StremEye - http://www.elecard.com/en/download/products.html

3. Remember that Testers section patches are for testers. Use simple bitrate patches.

4. How can I make encoder hold better in low detailed scenes?
Use Auto Quantizer patches.

5. How to update firmware:
a. Load GH2 1.0E firmware, see 1. how to get it.
b. Check all necessary patches, Version increment must be always checked.
c. Save firmware. Just change last digit to any number you want.
d. Copy firmware to root of SD card. Fully charge you battery. Do not even attempt to use AC coupler!
e. Power off your camera if it was on.
f. Power on camera. After this press (not hold) green play button.
g. You'll see hourglass and prompt to update.
h. Press down arrow and after this Menu/set.
i. Wait until upgrade will be completed.

6. How to privide reports in this topic?
0. Post here only problems and questions about new patches. For all else we have special topics.
a. Use systematic approach (one-two changes at a time with careful thinking).
b. Shift-Click on round button in PTool to save your particular settings.
c. Paste here settings with detailed observation + MediaInfo screenshot + StreamAnalizer screenshot.

7. If anyone wants to share uncompressed video - you can use http://www.pipebytes.com/ or http://www.sendoid.com/ to instantly share very large files.
Of course you need good connection as it uses p2p tech.

So here's what I did:

Prep:

1. Downloaded pTools 3.62D
2. Downloaded base firmware
3. Grabbed Driftwood patch

Process:

(I first preformatted the card in-camera)

1. I open pTools 3.62
2. I load base firmware.
3. I choose setting "B"
4. I save firmware as GH2_V11.bin (original GH2_V10.bin)
5. I load SD card with bin file in root directory.
6. I press playback button.
7. I get "No Valid Image to Display."

When I did the same thing with my GH1, I would get the prompt if I wanted to version up.

Sorry but on the road for a few days so may be slow to respond. All the detail is on my blog. Dunno how to upload file here so if someone wants to download it and add it that would be great. In summary.................


Folks,

Once in a while a revolution occurs that sets up the little guys for success. For sooooo long it has impossible to get a combination of an affordable large sensor camera that is; good in low light, that has minimal aliasing, that has a great codec, that has interchangeable lenses, that is convenient enough to put in your pocket, that is small enough to shoot without attracting attention etc. That is until the GH2 came along. But oh the codec – what a disappointment. Although it was 24 Mb/sec AVCHD those of us who were used to HDMI capture were never satisfied. Mud, compression artifacts and poor colour grading potential. UNTIL NOW!!!!!

A well known hacker in the GH2 community called Vitaliy permitted me to be part of the HDMI beta testing team but it became clear that in camera recording was so much more convenient and recquired fewer tricks. So……….. I tweaked and tweaked until I came up with a patch that gives all wanna be indie movie makers quality that they only dreamed of months ago IMHO. This patch will in most cases give you sustained 20 megabytes a second data. That is close to Cineform data rates. In fact conversion to Cineform has a similiar data rate. Stock up on SD cards and batteries – your gonna love it!!!!! I have 6 now as the average data rate will be about 1,2 Gigabytes a minute. If the files do not span that means an average take of 3 and a bit minutes. You need the Class 10 Sandisk extreme 30 MB/sec cards HD Video. Avoid UHS1 cards for now. No real issues as far as stability goes as long as you follow the simple rules. Use manual lenses or use your Panansonic micro four thirds lenses in Manual mode and focus prior to shooting.

If you are interested in colour grading with Cineform looks check out my post here and I have included some free looks.

Thank you Vitaliy. YOU ROCK!!!!!

Ladies and Gentlemen. I Present to you the Holy Grail of independent movie making…………….. the Henry Olonga Holy Grail patch for the GH2

ENJOY!!!!!!!!!!!!!!!!!!!!!!!!

I followed the given instructions to a tee, also watching 2 youtube videos, just to make sure I was doing everything correctly. I still could not get the camera hacked. I spent so much time trying to do this because my Ego could not accept that a pretty computer literate guy could not do something that seemed so simple to do. After every try and puting the SD card Class 10 in my camera, I would just get the error message about there not being any media on file for the camera to read when I pressed the play button. I am very sure that I did everything correctly, as I must have gone thru the process about 30 times over the course of the day. I am extremely frustarted. Can anyone help? Are there any new services out there springing up that can help you do this? I used 3 diffecrent cards and got the same outcome. I even went to buy a card at WALMART when my other two cards would not do the trick!!! I went online to try and download the latest version of ptools. I have ver. 3.40.

1. I have hacked my previously unhackable GH17 with all of the popular patches and a couple of my own modified patches using ptool 362.

2. Of all patches I have tried, lpowell's max latitude 100mbps patch seems to have the highest average bit rate according to Media Info.

3. Media Info says the max latitude patch has a max overall bit rate of 108 Mbps and averages 20.8 Mbps

4. Media Info says that footage from my unhacked GH17 has a max overall bit rate of 18 Mbps and averages 11.8 Mbps

5. Once my footage is transferred into Final Cut Pro 7 using Pro Res 422, the data rate in FCP7 of my unhacked footage averages 17 MBps while the data rate of my hacked footage averages about 13.5 MBps.

6. This discrepancy makes no sense to me. And moreover it would seem that if you edit in FCP7 that you are better off not hacking the GH1. Is this assumption correct? Can someone share more information on this issue?]]> https://personal-view.com/talks/discussion/521/72025p-strange-behaviour-on-gh2.- Thu, 28 Jul 2011 05:31:48 +0000 rogerpilly 521@/talks/discussions
The footage looks really good to my eyes and plays smoothly on camera and using VLC with the RAW footage. So, I tried to import it into FCP with conversion to Apple ProRes, as I usually do. Big surprise, at least to me that I don't understand how the coded technically works. The clips play at 50% speed, in a perfect and beautiful slomo! But it's not what I want! And also the second half of the clip does not get imported.

In other words, I see the entire clip in the preview window of the Log and Capture Tool (even though, if I try to play it, it doesn't play smoothly, it's all chopped, as if it had difficulty interpreting the TC) and the duration is correct. When imported, the duration of the clip is the same, but at 50% speed, so the clip ends after the first half.

Does anybody has an explanation? And, more important, does anybody know a work around to be able to use the footage? I would prefer at normal speed, but even in slomo it could be okay if I could capture the entire clip!
Thanks!]]> https://personal-view.com/talks/discussion/350/80mbit-mjpeg-43-for-2x-anamorphic-shooting Thu, 07 Jul 2011 14:58:02 +0000 EOSHD 350@/talks/discussions
No settings for this apart from the resolution / size change as was default in PTools for MJPEG.

Today I am testing new MJPEG encoder settings for improved image quality.

I have started off with these settings by CRFilms and LPowell as a basis http://www.personal-view.com/talks/discussion/comment/1762#Comment_1762

The purpose of these settings is for those with 2x stretch anamorphic lenses to get true 2.35:1 cinemascope from the GH2, rather than the more extreme 3.55:1 aspect ratio generated the lenses when used in 1080p 16:9 mode. I much prefer the less extreme cinema standard of 2.35:1 or 2.39:1, since that is what these anamorphic lenses were intended to make with 4:3 35mm film.

Today I have found MJPEG settings that seem to work well for recording quality and so sharing them here. I'll also share my further tests here. There is always room for improvement and new discoveries. The GH2 is good hardware, faster than the GH1 so who knows how high we can push it?

Rather than use 1440x1080, 1280x960 is necessary to avoid corruption, unexpected clip curtailment and enable the much higher bitrates.

Bitrate with my settings is approx. 80Mbit (variable). VLC Player reports a stream between 65,000kb and 85,000kb per second. 80,000kb is 78Mbit (http://www.google.co.uk/search?hl=en&safe=off&biw=1504&bih=877&q=80000+kb+in+megabits&aq=f&aqi=&aql=&oq=). Please correct me if I am wrong on anything technical. The footage looks great so far in this mode.

I need to do more reliability testing and see how far we can push it. Yet to find the final 'sweet-spot' but these settings are a good starting point for fellow testers.

480p Width: 1280
480p Height: 960
F1 Quality=280
F1 Table=4
F2 Quality=250
F2 Table=10
F3 Quality=225
F3 Table=24
F4 Quality=200
F4 Table=48

Lens was a LOMO 35mm 2x anamorphic in OCT18 mount.

I did not change any other settings.

A big thanks to Vitaliy and every tester, giving up valuable time for the good of the community. I salute you! - Andrew]]> https://personal-view.com/talks/discussion/1041/using-low-bitrate-for-accurate-framing-and-very-long-shots Tue, 27 Sep 2011 15:56:30 +0000 nomad 1041@/talks/discussions
Did anybody test how low we can go with the hack? I'm thinking about forcing the camera into record for a long time (for time-lapse, actually) and recording externally with a Ninja. But since we need to have the camera recording to get the same quality via HDMI, this is a bottleneck. There are already solutions for extended power supply and a Ninja can record for hours uninterrupted, but the GH2 needs to stay in record too (the recording will never be used, of course).

Suggestions for stable values, anyone?

TIA

As all Pro topics it is intended to testers who want to help and understand that they are doing.
If you do not understand, either ask or just read and wait.

* Try to format SD card using exFAT file system
* Check how it works in GH2
* Combine two large MOV files making them >2Gb, and >4Gb. Check if they can be played back in camera.]]> https://personal-view.com/talks/discussion/995/gh2-ninja Tue, 20 Sep 2011 14:53:17 +0000 djhessler 995@/talks/discussions
1. record in 24p in your gh2, connected to ninja recording
2. move your footage to your HD
3. open Adobe Media Encoder CS5 and drag a clip to it
4. VERY IMPORTANT... select clip in AMB cs5 and go to FILE, INTERPRET FOOTAGE,
5. select "Use Frame Rate from file 30.0000 (30p) Pixel Aspect stays the same
6. Field Order select "Conform to: Upper Field First" IMPORTANT
7. CLICK OK
8. now ur footage is interpreted as 30 interlaced, click on SETTINGS
9. AND render to preferred format to 23.98, I used Apple Pro Res HQ and my footage looks good.

can some of you confirm if this actually works? I know transcoding is an extra step, but doing it like this is pretty simple, specially if your on a mac like me and dont wanna go the PC route to transcode and fix the crippled HDMI footage.

Cant wait for you guys to try this out.

On a second note, I'm working on a cage specifically for the GH2, with lots of mounting options, good access to battery, hdmi, and audio input, I'll keep you guys posted as soon as I get it milled.
