Noctilux f/0.95 vs Hyperprime T0.95, shot on GH2 ! https://personal-view.com/talks/discussion/2613/noctilux-f0.95-vs-hyperprime-t0.95-shot-on-gh2- Mon, 19 Mar 2012 05:18:19 +0000 sebfarges 2613@/talks/discussions

Yesterday I had the opportunity of using for 30mn the Leica Noctilux 50mm f/0.95. I went to shot some video in the funfair of Bordeaux. I did not have ND variable filter (Leica is 60mm filter thread), so I had to use fast shutter speed, so sorry for the jitter effect... I try to do my best in this short time with this 8000€ lens. Today I went to the same place at the same hour with my SLR Hyperprime 50mm T0.95 lens, and I did the same shot, in the same condition (short time and no ND filter). This movie is a quick test where you can see in a alternate editing the difference between these two lens, wide opened at 0.95. This was not shot the same day so the light is a little different, but the weather was quite the same (cloudy with sun sometime).

All is shot at full aperture, 0.95

My opinion ? mmmm the Noctilux is an extraordinary lens, good rendering at f/0.95, smooth aperture ring. This lens is a little smaller and lighter than the SLR Magic lens. It's in M mount (Leica). The problem : the Noctilux is too expensive for me, 8000€ (10600$) !!! Please note that the SLR Magic I've used here is a prototype lens. It's be available in september in M mount, it's price is not fixed yet, but it will be around 2300€ (3000$), 3.5X less cheaper than the Leica.

The music mix is an homage to a movie director and one of his movie. The first who will find the name of the director and the title of the movie will win the two lenses... (I'm joking ;) ).

GH2 Mode dial stuck on Auto mode https://personal-view.com/talks/discussion/23785/gh2-mode-dial-stuck-on-auto-mode Tue, 21 Apr 2020 18:33:45 +0000 LawrenceDee 23785@/talks/discussions Hi there. I'm new to this forum and recently purchased a few Panasonic GH2s and patched them with Sanity X hack with plans to use them to film small concerts. One of the three that I purchased has an interesting issue where the mode dial at the top of the camera seems to be fixed in Auto mode and doesn't seem to change to other modes except for Progressive. The letter on the bottom left side of the LCD displays A mode and only changes to P when I move the mode dial to P. The camera does not seem to switch over to Movie mode or AI or any of the other modes when I turn the dial at the top of the camera. This particular issues was already present before the installation of the Sanity X hack and the issue continues to persist. I would like to use this camera for it's manual video mode in Cinema 24p and would like to know if there is a solution for this issue.

I have a quick video of both my cameras. The first camera is the one with the issue and I have followed by another GH2 which is functioning reliably and well with the Sanity X hack patched in. [

]

Ideas and/or suggestions on what I could try would be appreciated.

A big thanks to those who have placed so much effort into creating hacks for the gh2. I hope to explore the true value of a hacked GH2 as I navigate my way around this site.

Used GH2, sensor streaking or flaring https://personal-view.com/talks/discussion/23748/used-gh2-sensor-streaking-or-flaring Mon, 06 Apr 2020 18:05:57 +0000 TreyM 23748@/talks/discussions Hello all,

I just bought a used GH2 from eBay. When I got the camera, I quickly noticed some horizontal magenta sensor flaring/streaking when pointing at a bright light over a dark background. I tested the same lens on a GH4 and the issue was not present, so I am certain this is from the sensor. I sent the following video to the seller and he refunded me and told me to keep the camera. Is the behavior in the video below known behavior for the GH2, or is it indeed faulty? This is the only lighting scenario where the camera does this. It is otherwise perfectly fine and usable. Admittedly, the ISO is really high at 3200, but I'm hoping it's not normal GH2 behavior.

Easy script for drag&drop merging of spanned AVCHD .MTS files (in Windows) https://personal-view.com/talks/discussion/19340/easy-script-for-dragdrop-merging-of-spanned-avchd-.mts-files-in-windows Mon, 02 Apr 2018 12:15:02 +0000 MrZz 19340@/talks/discussions Today I needed to merge some spanned AVCHD/MTS files (because of the 4gb file soize limit on the fat32 capture card) together into one on my workstation. I just searched for this script which I normally used but since I couldn't find the script on my system, I rewrote it and thought I'd share it. Just for everyone else who has some use for this handy little script here's the code:


echo off
title Merge Files

set /p choice="Enter path to merge to: (eg. C:\video\test.MTS)"

if "%~1"=="" exit
if not "%~1"=="" SET one=%1
if not "%~2"=="" SET two= + %2
if not "%~3"=="" SET three= + %3
if not "%~4"=="" SET four= + %4
if not "%~5"=="" SET five= + %5
if not "%~6"=="" SET six= + %6
if not "%~7"=="" SET seven= + %7
if not "%~8"=="" SET eight= + %8
if not "%~9"=="" SET nine= + %9

copy /b %one%%two%%three%%four%%five%%six%%seven%%eight%%nine% "%choice%"

echo AVCHD Joining Complete.
pause

Just copy this code into a .txt and rename into .bat. Then you can just drag and drop the files, by selecting them and drag the first one on the .bat. You will then be prompted to input a destination path and name. You can merge a total of nine files into one this way.

Cheers!

Do we really need the GH4 and 4:2:2, 10 bit, 4K, Raw file? GH1 and GH2 still rock for me https://personal-view.com/talks/discussion/9608/do-we-really-need-the-gh4-and-422-10-bit-4k-raw-file-gh1-and-gh2-still-rock-for-me Thu, 13 Feb 2014 04:20:33 +0000 eurocameraman 9608@/talks/discussions I am just asking myself a simple question I would like to share with the independent filmmaking community: Do I really need all of this? 4:2:2, 10 bit, 4K, Raw file, ProRes… Do I really need to invest as soon as something new and fancy is coming out?

On my own experience, I would say not so sure as I am very pleased with the result I am getting out of my GH1, GH2 and now GH3. And my GH3’s video is not making a huge difference compare to what I got with the GH1 or GH2. I am still using the hacked GH1 every summer, as a copy is stored in my home country (France) and I love its color rendition compare to GH2/3. FYI, I am living and working in China since 9 years.

Every year I am shooting a short movie or an experiment with the hacked GH1. Some complained about the AVCHD format, but I never got problem in post with it as I am using Premiere CS6 on a powerful enough PC (Dell M6400). I also tested heavy color grading without problem on my GH1 footage, as you can see here on the following videos. Sorry one of the short film doesn’t get English sub yet, but I am posting a link to those video for their visual quality first, so enjoy that part. La Deuche from Hell HD (US sub Version) (there is a longer French version too)

Revolverte HD (F)

In China, I am also using my GH camera beside a Panasonic AF100, which is well known to NOT be the most exciting camera on the market (4:2:0 8 bits, AVCHD at 28MB/s, what a shame!). I had to buy an AF100 as no serious client in my field would accept to pay my usual fee (I was working with a HVX200 + Letus Ultimate prior to the AF+GH) if I were shooting with a GH2 only. After 2 jobs my AF100 got paid back and I can enjoy the use of it with my GH2 and GH3 on project now. ,

AVCHD, 4:2:0, bits… Nevertheless, I shot this Making Of video on huge project with my newly arrived AF100 and GH2 (not hacked yet). Production house, agency and client were delighted by the result. I did everything: shooting, lighting (for interview), sound recording and editing… I am a one man crew shooter (kind of MacGyver sometime) and I prefer to keep things, cheap, simple and light. CrossPolo TVC Making OF HD (US)

To keep the story short, since 2012, I had completed bunch of projects with my M43 equipment without any complain from clients (VW, Audi, French Consulate, TV Channel…) and I might invest in the GH4 if it solves the 3 main problems of the GH3: Viewfinder definition (GH3 is a nightmare compare to GH2 for manual focusing) + real video assistance (Peaking + zebra + waveform) + full time display of histogram and sound recording level while shooting.

4K or higher bit rate are not important to me as my video will NEVER be projected on a big screen and the file of the GH3 are already big enough in term of storage. Quality wise, I really like some of my GH1, GH2 or GH3 shots, and I don’t see much of a difference in term of emotion, and I think this is a more important feature for an independent filmmaker than pixel count or comparing numbers on data sheets…

Why no 400mm or longer M43 Lenses https://personal-view.com/talks/discussion/6349/why-no-400mm-or-longer-m43-lenses Wed, 06 Mar 2013 17:46:54 +0000 ragnar 6349@/talks/discussions I might be answering this question myself but I would still like to hear from others on this topic. As far as I know 300mm is the top end for M43 lenses. I own the Pana 100-300 lens and use it a lot for bird photography and I enjoy its qualities. I'm wondering if there is a specific technological reason why neither Pana or Oly have not come out with a longer M43 lens. Is it just a size consideration as it would be too big for M43 cams? I guess I could understand that. Maybe there is no demand for anything longer than 300mm for M43?

I've adapted several longers FD lenses to my GH2 and it works of course but I would really love a true M43 400mm or longer lens. I suppose with the Metabones thingy I could adapt a Canon 600mm EF lens and go that route but that'll cost many benjamins for sure. My 100-300 lens is very portable so I think that 400mm could be done but perhaps 300mm is the technological sweet spot for M43 cams and lenses and going 400mm would be just too difficult?

GH2 to super-8 cinema format https://personal-view.com/talks/discussion/21676/gh2-to-super-8-cinema-format Thu, 07 Mar 2019 06:39:56 +0000 agaraster 21676@/talks/discussions I'm trying to setup a patch to make the GH2 as similar as possible to a super-8 cinema camera. On the hardware side I have mounted an angenieux 8-68 f1.9 and it's all good with the ex tele mode.

I would like to change the sensor coverage of the MJPG mode, but it's hard for me to find a way.

The patch i'm starting with is flowmotion 2. Sensor coverage is great on ex-tele combined with both "cinema 24P mode" and "HBR" mode. On MJPG and 720p the sensor coverage is smaller than the above, and this is what i'd like to fix.

What I'm trying to achieve, at the end, is a final result of film 3:2 aspect ratio 1920x1280 frame, possibly @24p or 25p.

Any suggestion?

Replacement for the stock battery for G7, GH2, possibly the new G85 https://personal-view.com/talks/discussion/15833/replacement-for-the-stock-battery-for-g7-gh2-possibly-the-new-g85 Sun, 02 Oct 2016 11:32:48 +0000 DrDave 15833@/talks/discussions Actually, a good replacement for the stock battery. Maybe more. For G7, GH2 &c. possibly the new G85

I use a lot of the BLC12 Batteries. I buy the Panasonic ones; they aren't cheap but they last the longest and don't turn the camera off with no warning.
However, I do buy aftermarket batteries for testing from time to time. They often have very high ratings, and they never work very well.
A few years ago, I bought the DSTE "1600mah" battery. It had about 70 percent of the stock battery's power, and the stock battery is 1200 mah. So that's 840mah, or about half the advertised capacity.
A few weeks ago, I purchased the 1700 mah version at this link:
https://www.amazon.com/dp/B00MEAMBQU
It weighs 55 gm as opposed to the stock 50gm. Previous clones weighed 46 and 48 gm.
Now before you get excited, the extra weight is probably ballast, since you can't squeeze more cells into a battery, as a general rule.
However, after extensive testing, this battery is equal to--not better--but equal to stock. The only difference is that the shutdown curve is a bit steeper.
So it isn't "1700" mah, but it is basically a stock battery.
This was quite a shock, but I repeated the tests several times. In one test, I simply turn on the camera and record video until the battery croaks, and measure the time. Both the stock battery and the DSTE run the G7 for two hours of video, sometimes a few minutes more, sometimes a few minutes less. So, finally, an inexpensive option. At least for this batch. Also, see my post on the cheap external battery that will run your camera all day.

GH2: MJPEG 100Mbps Low Light 1080p Settings https://personal-view.com/talks/discussion/479/gh2-mjpeg-100mbps-low-light-1080p-settings Sun, 24 Jul 2011 16:53:31 +0000 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:

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.
