Yesterday driftwood released what is probably the last and greatest update for hacked GH2 cameras.
This group of settings is called Apocalypse Now and works to achieve a better and smoother color matrix that not only improves upon the native 4:2:0 h.264 of the camera, but also softens the natural sharpness of the Panasonic lenses when used in video mode.
If you have a higher-end monitor capable you should be able to see the subtle changes in color rendition to the blue channel in this still.
These are just preliminary tests, but I would hazard to say that I would now recommend using Panasonic electronic lenses without fear of sharpening artifacts.
1. Make the mount extender detachable.
Right now the Canon EF/Nikon ZF mount sits past 40mm from the sensor. I know I went over this in my last post, but by reducing this distance to NEX or 4/3 20mm distance, a whole range of lens options open up. Lens options that work better with the 15.6mm wide sensor (2.1x 35mm FF crop)
2. Allow for line skipped higher framerate modes.
Cameras like the new FS700 change the sampling of the sensor to allow higher framerates. For instance, at 240fps you see a decrease in vertical resolution over the 120fps and slower modes. Certainly there may be limitations with the onboard cpu that might make this impossible, but if it is, people will gladly take a small resolution hit to get 60fps, or even 48fps like the Scarlet X at 3k. At the same time, it is also important, even without higher framerates, to have ramping options available in camera from 1-30fps.
3. Timelapse mode.
It certainly hasn’t been mentioned yet as far as I can tell, but a RAW timelapse mode would be incredibly useful for this camera. Settings for variable slow speed frame rates as well as long duration shutter exposures would be equally useful.
4. RGB Histogram.
Monitoring the image/exposure should be done exactly as Red does it. They’ve perfected the RGB histogram and it is essential for RAW cinema applications. Shutter should also allow for settings in shutter angle as well as further synchroscan settings for shooting monitors and other equipment.
Technically this isn’t 4k. It’s not even 2k, but it is the best way to upload your footage to youtube or Vimeo for the absolute best quality and for future-proofing your work. Here was the first test of “4K”
click “ORIGINAL QUALITY”
So what is going on here, and why should I do this? First, I created a 4000×1800 project in Sony Vegas 11. I interpolated the anamorphic footage shot to the correct aspect ratio, and “graded” the footage in Magic Bullet looks – Let me show you some examples of the benefits.
Taken sample from this video (which was done at 2k)
Now, if you control the master that you upload, every downsample will be from that file, but if you upload at 1080p or below, your future footage can only be upsampled from that lower quality master and who knows what method will be used to upsample when the age of 4k or 8k hits us in the upcoming decade. Also if you upload at 1080p with anamorphic footage, its quite posible that you will actually lose vertical resolution if your footage is encoded with bars. 4k or even 2400×1080 will make sure that your footage wont be downgraded before it goes through your favorite host’s compression.
Here’s an example of the cheap +1 Cokin P diopter in the cinetactics Matteblox. It is a velcro mounting system, so the adapter is mounted in velcro and can firmly attach close to the lens. There is no possible chance of this falling out accidentally.
One camera is a Hacked GH1 at 100mb, the other is a GH2. One camera is cropped to 2:35.1, the other actually has the anamorphic lens. They are mixed almost exactly 50/50
Here’s a quick little vlog testing the differences between the GH1 and GH2 (exact same settings) at ISO 1600 and 3200 respectively.
The GH2 has come quite a ways forward from the GH1 in terms of processing high ISO video.
Here is the first video in a new series of tutorials for the Panasonic LA7200G anamorphic adapter. We’ll be diving into its flaws at multiple focal lengths and apertures.
This first video focuses on the 14-140 lens and using the adapter wide open from 17mm to 70mm
Thanks to the youtube “Original” quality mode, you can now enjoy anamorphic videos like the one below in super high resolution, higher than any other online streaming site. While the quality is not as good as looking at the raw files, it certainly makes for a whole new online viewing experience.
This video was shot during the testing of our LA7200 adapter in preparation for a new anamorphic lens tutorial series.
