Hacks and Patches http://personal-view.com/talks/categories/hacks/feed.rss Thu, 20 Jun 19 17:41:56 -0600 Hacks and Patches en-CA GH2 Hack Technical Tests http://personal-view.com/talks/discussion/753/gh2-hack-technical-tests Wed, 24 Aug 2011 14:12:57 -0600 cbrandin 753@/talks/discussions
To accurately measure quality improvements you have to see how footage reacts to the processing that takes place when it is converted to the RGB domain - in other words, when it is rendered. For these tests I used this chart:

image

In order to make the effect of the raised quality reatures most visible I set AQ to 4 (all to detail) for these tests. Frame grabs were exported in a lossless format to Photoshop. In Photoshop, I used levels to examine image portions in a restricted range in the shadows. Photoshop interpolates values within this range to produce the final image. The quality of that interpolation is very dependent on the quality of the image. It's very similar to how any kind of editor will work. As a reference I also took a still image of the chart using the highest quality the GH2 can prduce and processed the raw file. Following are histograms taken from these processed images. The lines in the histograms show quantization artifacts - you can actually see how fine (or coarse) the quantization is. This relates directly to image quality, and how far you can go with post processing and still have a good image.

Still Image:

Factory Firmware at 24H:

24H set at 44M with AQ=4:

As you can see there is a significant improvement at 44M and an additional, but not as big an improvement at 66M (mostly in the deep shadows).

GH5 - impossible to unlock VLOG? http://personal-view.com/talks/discussion/20700/gh5-impossible-to-unlock-vlog Sat, 20 Oct 2018 01:26:43 -0600 GHuser 20700@/talks/discussions I remember the GH2 and Ptool hacks back in the day. With all the great features built into modern cameras like the GH5 there is less of a need for hacks, but it is curious that no one has hacked the GH5 to enable VLOG. Is that because it is impossible to enable VLOG using a firmware hack, or because no one has sufficient interest in creating a hack?

Can't get GH2 to go to "BODY VERSION UP" http://personal-view.com/talks/discussion/21995/cant-get-gh2-to-go-to-body-version-up Thu, 02 May 2019 07:06:04 -0600 murphy 21995@/talks/discussions Hi, really like this website, I've been looking at it for a good while but today I've finally decide to hack my GH2. I've followed all the steps but just at the final part I cannot get it to update.

I have the hack on the freshly formatted card but when I turn on the camera and press the green play button, it just says "NO VALID PICTURE TO PLAY", when I should really get the option of "BODY VERSION UP". I know it must be something simple I'm missing but any help would be great.

Thanks a lot M

Guide: Sony A7III/A7RIII/A9 Firmware Language mod http://personal-view.com/talks/discussion/21766/guide-sony-a7iiia7riiia9-firmware-language-mod Fri, 22 Mar 2019 04:54:29 -0600 saudkh 21766@/talks/discussions NOTE: this method is still pending an encryption method, but until then I thought it would be nice to prepare your firmware folders for when the update hits!

Today @ma1co (https://github.com/ma1co/fwtool.py) released an update to his fwtool.py tool that allows you to extract gen4 firmwares. The tool only allows you to decrypt the firmware at the moment, but I am sure it will only be a matter of time till he updates it to encrypt as well.

The method below was discovered by @vitaliy_kiselev and can be found here: https://www.personal-view.com/faqs/sony-hack/languages

NOTE2: this method is not only untested, it will likely brick your camera. Proceed with caution.

Preparation (for macOS)

  1. Download the full source fwtool.py from the link above
  2. Download the actual firmware for your camera, in my case for the A7III it was (https://www.sony.co.uk/electronics/support/e-mount-body-ilce-7-series/ilce-7m3/downloads/00015677)
  3. copy the .dat firmware file from the dmg to the fwtool root folder
  4. sudo easy_install pip
  5. sudo pip install pycrypto
  6. sudo pip install pyyaml

note: if at any point you found any of these steps confusing or indirect, you should stop and not do this

Guide:

  1. python fwtool.py unpack -f FirmwareData_ILCE7M3V210.dat -o out (this is on macOS Mojave, your OS might require something different)
  2. cd out/firmware.tar_unpacked/0110_backup/SYSASTRA-DSLR/TI
  3. Swap the files of your current language (I have J1, see below list section as a reference. note that there are now 2 ALLLANG files one with CX62200 and one with CX62201 choose the one that corresponds to your camera language) with the All Language file (just rename them)
  4. cd out/firmware.tar_unpacked/0111_backup_sum
  5. edit 'backup.sum' in your favorite text editor
  6. Swap the checksums with what ever language you have with the CX62200_ALLLANG bin file checksum

    0,ae35017d,00113eba,000001a4,00000000,000003e8,root,root,-1,-1,SYSASTRA-DSLR/TI/CX62200_ALLLANG.bin, 0,782ddbc1,00113eba,000001a4,00000000,000003e8,root,root,-1,-1,SYSASTRA-DSLR/TI/CX62200_J1.bin,

    becomes

    0,782ddbc1,00113eba,000001a4,00000000,000003e8,root,root,-1,-1,SYSASTRA-DSLR/TI/CX62200_ALLLANG.bin, 0,ae35017d,00113eba,000001a4,00000000,000003e8,root,root,-1,-1,SYSASTRA-DSLR/TI/CX62200_J1.bin,

  7. Wait till we have a way to encrypt it. I just cant thank ma1co enough for making this possible up to this level! you rock. I will update this guide with results once ma1co releases an update.

List:

  • Region ALLLANG .. I mean you should know what this means otherwise you should not do this.
  • Region J1(JPN) supports Japanese only
  • Region U2, CA2, AU2 supports English, French, Chinese,
  • Region CEE2 (CEE) supports English, French, German, Spanish, Italian, Portuguese, Dutch, Russia, Sweden, Danish. Norway, Finnish, Poland, Czech, Hungarian.

How do I Make/Get a prism for a three sensor setup? http://personal-view.com/talks/discussion/21422/how-do-i-makeget-a-prism-for-a-three-sensor-setup Tue, 29 Jan 2019 05:23:04 -0700 mei 21422@/talks/discussions I couldn't find a hardware hack/maker specific category here, so I hope that this is the right one.

I've come across some pretty nice sensor chips related to one of my cameras. So, I'm curious about getting a 3-chip prism I could attach them to. I literally could buy three devices that used them, strip them, and attach them to the prism. I've heard about making them many years ago, so which ever is easiest.

This is a curiosity.

A little bit confused "gh2 hacks" http://personal-view.com/talks/discussion/20320/a-little-bit-confused-gh2-hacks Fri, 24 Aug 2018 09:58:26 -0600 disease8 20320@/talks/discussions Hi there I wanted to try out the driftwood hack and I am totally confused. I installed what should be the 176mb version and the footage looks so bad its worse than before the hack. It has terrible aliasing everywhere and looks much more compressed than default. I then looked to try and download it again but after looking through all the pages and hacks I am totally confused.

What is the quantum x patch? Is that the same?

I just want the highest possible quality but also I need it to be stable as I intend to shoot some b roll for my documentary with it. I also wanted to have the audio patch on there and I tried to add the mjpeg one to. I blended the different patches with ptool on my macbook (you have to press CMD instead of alt). I thought maybe the patches were somehow conflicting with eachother but I checked in ptool and it seemed not.

Am I missing something obvious?

I have attached a clip from my apparently driftwood hacked gh2, as you can see it looks very compressed with really back aliasing and mud.

GH2: MJPEG 100Mbps Low Light 1080p Settings http://personal-view.com/talks/discussion/479/gh2-mjpeg-100mbps-low-light-1080p-settings Sun, 24 Jul 2011 16:53:31 -0600 LPowell 479@/talks/discussions
http://www.personal-view.com./talks/discussion/3337/gh2-flow-motion-v2.02-720p-reliability-in-auto-exposure-modes/p1

As numerous GH2 owners have discovered, Vitaliy's recent updates to PTool have enabled the newly hacked GH2 to sustain remarkably high bitrates in MJPEG HD mode. What's even more impressive is that the GH2 maintains error-free recording stability at bitrates significantly exceeding those that can be used reliably on the GH1. And where the GH1 struggled to produce FHD-size videos in MJPEG mode, the GH2 can be readily patched to record in any MJPEG frame size, all the way up to 1920x1080p.

The MJPEG encoder's most valuable asset has always been its ability to record each video frame as a JPEG-encoded key frame. This enables it to track high-speed action at 30fps without any of the smeared motion artifacts that plague low-bitrate AVCHD videos. To produce high-quality, detailed key frames at 1080p, however, an Intra-frame encoder must work at higher average bitrates than the GH1 was able to sustain. With PTool's support of the GH2, it is now possible to use MJPEG HD mode to produce reliable 1080p videos at an average bitrate of 100Mbps in sharply-focused, highly-detailed scenes.

The MJPEG encoder also excels in difficult low-light conditions where the AVCHD encoder cuts down its bitrate to minimum quality levels. On the GH1, MJPEG HD mode could be relied on to produce bitrates over 24Mbps even in dimly-lit scenes. With patch settings optimized for consistent bitrate production, the GH2 can maintain high bitrates of up to 100Mbps across the entire exposure range, producing high-quality images under any and all illumination levels. Combined with the GH2's low-noise image sensor, MJPEG HD mode can render clean, gradable images in conditions that the GH1 would have found hopelessly underexposed.

MJPEG image quality with exposure bracketing

Below are 100% crops of two series of four bracketed exposures I took in MJPEG HD mode, patched to 1920x1080 resolution. For each shot, I set up the GH2 on a tripod with a fixed aperture at ISO160, and varied the shutter speed from 1/60 to 1/500 second, producing videos bracketed at one-stop exposure steps. Frame grabs were then composited in Photoshop and saved at maximum JPEG image quality. These scenes were selected as typical outdoor subjects shot in natural lighting, as opposed to shots of extremely detailed foliage. The GH2 exhibited no reliability issues whatsoever, and recorded all videos at impressively consistent bitrates of around 90Mbps.

iPad compatible MJPEG VGA video mode

In addition to MJPEG HD mode, recent versions of PTool have provided patches for adjusting the frame size and image quality of MJPEG VGA mode as well. Unlike the HD 16:9 aspect ratio of HD mode, VGA video mode records with an SD aspect ratio of 4:3. I've optimized VGA mode to produce 960x720 videos at consistent average bitrates of about 30Mbps. These videos are compatible with the maximum-quality download specifications of the Apple iPad, with its 1024x768 screen resolution.

GH2 Patch Considerations

Patches for the GH2 are currently in active development by numerous testers, and Vitaliy has updated PTool several times with exciting new features. The patches in the downloadable PTool INI settings file below have been systematically tested using PTool version 3.61d and have produced no reliability issues to date. This patch is designed and tested only for the fastest Class 10 SDHC cards currently available.

Additional points of interest:

* The 100Mbps GH2 Low Light MJPEG 1080p Patch is compatible with all GH2 cameras, and is switchable between NTSC and PAL modes.

* I recommend using the camera to format your SD card at the start of each shoot, to guard against SD card memory fragmentation.

* Peak bitrates are obtained only with sharply-focused, highly-detailed subject matter. Average scenes will produce average bitrates.

* High bitrate MJPEG videos may not play back reliably in-camera or on low-powered computers.

* If shutter speed is set longer than the frame rate (e.g. slower than 1/30 at 30p), low-quality video files may be produced.

*** WARNING ***

The 100Mbps GH2 Low Light MJPEG 1080p Patch will not work properly with previous versions of PTool. My thanks once again go to Vitaliy Kiselev, for his pioneering work on PTool, and to cbrandin for his invaluable Stream Parser tool.

The best way to insure that you have the latest PTool release is to download it directly from the following link:

Download PTool here: http://www.gh1-hack.info/ptool3d.zip

100Mbps GH2 Low Light MJPEG 1080p Patch Settings File:

For use with PTool v3.62d and above, I've prepared anamorphic as well as standard aspect ratio settings files:

* For use with standard lenses, the standard patch will produce two types of MJPEG 30p videos:

HD mode: 1920x1080 HD videos, with peak bitrates up to 100Mbps.
VGA mode: 960x720 iPad-compatible videos, with peak bitrates up to 30Mbps.

* For use with anamorphic lenses, the anamorphic patch supports two different squeeze ratios:

HD mode: 1920x810 videos for 1.33X anamorphic adapters, with peak bitrates of 100Mbps.
VGA mode: 2160x810 videos for 2X anamorphic adapters, with peak bitrates of 100Mbps.

These zipped INI files can be used to apply complete patch settings to firmware loaded into PTool. To use, unzip the INI file into the same folder as the PTool application. Launch PTool and load the firmware for GH2 v1.0. The settings contained in the INI file will automatically be installed in the "C" button at the bottom of the PTool main window.

Note that with the following PTool Settings files, you may at any time re-install the original Panasonic GH2 v1.0 firmware into the camera. You may also copy each type of patched or original firmware to separate SD cards, and use them to quickly switch between patches as often as you like.

Recommend GH2 patch with working HDMI out http://personal-view.com/talks/discussion/19583/recommend-gh2-patch-with-working-hdmi-out Sat, 28 Apr 2018 04:22:15 -0600 radikalfilm 19583@/talks/discussions Guys. I currently have one of the patches on the GH2 (don't remember which one, they look the same to me) which doesn't allow for Live HDMI out at all, either recording or previewing. I was incredulous when I first discovered it but since I had to shoot the next day I left it as is and shot without external monitoring.

This time around I want to capture the HDMI output to a recorder (1080i50 on Blackmagic Hyperdeck Shuttle 2), so I need to improve on the situation. I would like to also record on the SD card for backup, though I don't care much for the bitrate.

Should I revert to the Panasonic firmware? I seem to remember there are pulldown issues with that firmware (but HBR, which I will be shooting, is good maybe?). Is there a recommended patch I should load which gives solid HDMI out AND SD card recording?

THE END seems to restore a lot of the color, but not much else.

Was there something I was supposed to instantly recognize in the images that were hacked? Still really good quality, but I'm unsure if I actually used them correctly. After successfully installing the hack to my camera via SD, it gave me that notorious message, and obviously I continued with the installation, and waited roughly 30 seconds to a minute, as everyone says. I know it must have worked because my camera straight up froze several times while trying to shoot.

OLD DINOSAUR GH2 ALL INTRA AND GOP 2 http://personal-view.com/talks/discussion/17935/old-dinosaur-gh2-all-intra-and-gop-2 Mon, 09 Oct 2017 07:39:05 -0600 frullaccia 17935@/talks/discussions MANTRA & ZO. ALL-INTRA PATCH FOR GH2 (INCLUDING 1280X720). ZO. GOP 2 OPTION FOR 1280X720.

Mantra is the only existing all-intra hack for Panasonic GH2, including a stabilized 720p50 version. Mantra is for Pal system.

IMPORTANT! All-intra 720p50 mode has limitations. Using this, the camera sensor needs much more light than before. When shooting in low light or shooting in dark areas, the camera could freeze. Furthermore: choose the right iso settings. When shooting outdoor (daylight) a 720p50 GOP1 is fine. For low lights and indoor shootings use Zo, the GOP2 patch version.

Mantra and Zo 1080p24 shoot at 23,976fps.

GH2 Hacked - SanDisk Extreme Pro 95MB - Video stops at varying time without error http://personal-view.com/talks/discussion/2854/gh2-hacked-sandisk-extreme-pro-95mb-video-stops-at-varying-time-without-error Fri, 13 Apr 2012 10:07:56 -0600 thomasklosinsky 2854@/talks/discussions Hi guys,

I searched the forum and the whole internet for this problem, but didn't find any post or anyone having this problem, so I started a new topic for this and hope I didn't search for the wrong keywords... ;). I am using the GH2 for video shooting very short time and all I am doing these days is not really working well. I know that it should be easy to use firmware patches but for me it turns out not to be that easy as it maybe should. I used a few patches and tested around with each for quite a bit and tried to check wether the patch is working fine or if there are occuring errors while recording. I would need a very stable patch since I always need to record longer footage... not just 15min, but most of the time 2-3 hours. I found that SD card speed is a thing which is why I bought the SanDisk Extreme Pro with 95MB/sec. Used the Sanity 4.1 Patch which should be stable, but the cam stops recording video after some time (I couldn't specify when it does) without any error. It just stops recording and doesn't write the file completely to the card. Used the Quantum X SpanMyBitchUp and I get the same error. Also tried some other patches, some came up with errors that the card is not fast enough, some didn't... most of them didn't...

Since I can't tell why that is and I don't know how to find out why the cam stops recording I am not sure what to do next. Fact is that the patches really do enhance the quality which I would not love to miss ;).

Can anyone help me with this? All the best from Hamburg, Thomas

Costum Cropmarks / Framelines for Sony Alpha http://personal-view.com/talks/discussion/17626/costum-cropmarks-framelines-for-sony-alpha Mon, 28 Aug 2017 10:08:49 -0600 jeffcostello 17626@/talks/discussions Sony alpha cameras always take images in aspect ratio 3:2 but you can choose a 16:9 overlay if you prefer to take images in 16:9. As the camera always saves the images in 3:2 you need to crop the images later in photoshop to 16:9. Unfortunately 16:9 is the only alternativ format you can choose and I would love the possibility to see black overlays in any aspect ratio i want.

For canon cameras there is a reverse engineered software called „Magic Lantern“. One option within this software is the possibility to create your own cropmarks / overlays. You just create a photoshop file with two layers. A white background layer and a second layer with whatever shape you want. When you copy this photoshop file on the SD Card of your camera you can load it onto your camera. The second layer with your shape will then bye shown as an overlay. It´s meant to use it for different aspect ratios but you can also draw a flower and let it appear on your camera liveview.

Here is a link to that software: http://magiclantern.wikia.com/wiki/Cropmarks

For Arri cameras you habe the following option to create costum Framelines:

For Sony cameras there isn´t such thing but there seems to be a way to build android apps and install them on the camera to create new functions. My question is:

Is it possible to built an app for sony cameras that lets you create costum overlays that show in camera live view?

Best, David
