Here's how to get clean low light footage from the Panasonic GH4

I have heard from several video shooters who are concerned about buying or renting the Panasonic GH4 because they have heard that it has less than stellar performance above ISO 800.

To address this concern, Sohail over at Borrowlenses (one of our terrific sponsors) has posted a great blog entry on shooting with the GH4 at night.

He makes the interesting point that low light and high ISO are not necessarily the same thing - and that with fast enough lenses, shooters can produce great footage with the GH4 for night exteriors.

As an example, here's some 4K footage he shot with the GH4 at San Francisco's Fishermans' Wharf using the Voigtlander 17.5mm f0.95 and a Sigma 18-35mm f1.8 (with Speed Booster). Cleanest shots are between ISO 200 and 400 :

As Sohail says - shooting with superfast lenses doesn't give the GH4 the incredible light-gathering capability of the A7s - but it does give shooters the ability to deliver clean low-light footage at reasonable ISOs.

And for budget-conscious shooters, the additional benefit is that a $1698 Panasonic GH4 with a $799 Sigma 18-35mm f1.8 Nikon mount lens is about the same price as a $2498 body-only Sony A7s.

Yes, you'll need a $429 Nikon G to MFT Speed Booster, but that's less than the cost of a decent lens for the Sony.

If you need a camera that can essentially see in the dark, the A7s is the better choice - but if you want internal 4K recording and you occasionally shoot in low light, the GH4 will do a terrific job.

Best 4K Camera Deal - $100 off list price for a new Blackmagic Production Camera

Here's a great deal on a Super 35mm camera with a global shutter that doesn't need a paid firmware upgrade (e.g., Arri Amira) or a hack (e.g., Sony F5) to record 4K - the Blackmagic Production Camera.

With the addition of RAW recording, histogram, audio meters, and time-to-go in the last few (free) updates, this camera has come into its own. You can get one right now from Top-Rated 100% eBay seller AMG Studios in Ohio for just $2895 - $100 below list.

Only a couple are left at this price, so if you want one, you may want to pull the trigger now (and, if they're sold out, you can still get one by clicking on one of our sponsors' display ads below).  Thanks for helping to keep the posts coming.

Paul Ream's Sony F5 4K hack is real - Sony F55 owners not happy

Sony F5 owners just got an early Christmas present. Paul Ream's latest podcast describes exactly how he unlocked 4K recording on the heretofore 2K Sony F5 (discussion of Sony business ethics starts at 11:30 - legal caveats and technical discussion start at 17:15).

For those who need to see the procedure in writing, Paul has spelled it out:

Following on from our fourth podcast, this is the page where we’ve written the 4K4F5 guide down. It goes like this:
  • Save a 2K XAVC ‘All Files’ setting to a blank SD card.
  • Pop the SD card into your computer.
  • Go to the Private/Sony/PRO/CAMERA/PMWF5 directory.
  • Open the 001.ALL file with a plain text editor.
  • Delete the whole of the first line (32 digit checksum)
  • Change line 150 to one of the settings listed below.
  • Save the file as 001.ALL (Plain text)
  • Generate a new md5 checksum for the file.
  • Open the file in your text editor again and add the new checksum as a new first line.
  • Save and pop the SD card in your F5.
  • Enjoy your new settings which can then be copied in camera to taste.
Your choice of new line 150′s are:
  • 4K at 23.98 enter: 150=4096,2160,1001,24000,1,1,0,8,0,0,0,1,1,1,6
  • 4K at 24 enter: 150=4096,2160,1,24,1,1,0,8,0,0,0,1,1,1,6
  • 4K at 25 enter: 150=4096,2160,1,25,1,1,0,8,0,0,0,1,1,1,5
  • 4K at 29.97 enter: 150=4096,2160,1001,30000,1,1,0,8,0,0,0,1,1,1,4
  • 4K at 50 enter: 150=4096,2160,1,50,1,1,0,8,0,0,0,1,1,1,3
  • 4K at 59.94 enter: 150=4096,2160,1001,60000,1,1,0,8,0,0,0,1,1,1,3
  • QFHD at 23.98 enter: 150=3840,2160,1001,24000,1,1,0,8,0,0,0,1,1,1,6
  • QFHD at 24 enter: 150=3840,2160,1,24,1,1,0,8,0,0,0,1,1,1,6
  • QFHD at 25 enter: 150=3840,2160,1,25,1,1,0,8,0,0,0,1,1,1,5
  • QFHD at 29.97 enter: 150=3840,2160,1001,30000,1,1,0,8,0,0,0,1,1,1,6>/li>
  • QFHD at 50 enter: 150=3840,2160,1,50,1,1,0,8,0,0,0,1,1,1,3
  • QFHD at 59.94 enter: 150=3840,2160,1001,60000,1,1,0,8,0,0,0,1,1,1,3
To generate an md5 checksum on a mac you can simply use terminal. Just type “md5 001.ALL” when you’re in the same directory as the file. Finally paste the 32digit code back into the first line in the file.

Not sure how to do this on Windows but there are web sites that will generate an md5 file code just by dropping it on a page!

Alternatively, here’s all my ‘ALL file’ settings as an example. They were generated on my camera with firmware 4.11. These can be saved to an SD card and used directly in your camera. Once loaded you can change any other menu settings and save them to your own camera cards as normal.


It is very interesting to see the shock and outrage over this discovery on Philip Bloom's Facebook page among the F55 crowd, though.

Camera companies make business decisions that disadvantage consumers all the time - at both consumer and pro ends of the market. I don't know why people continue to be surprised by this.

That said, if you've been thinking about getting the F5, but have been holding out for 4K, now may be the time to pick one up from existing stock from retailers (they are still $16,490 at Adorama). Sony will probably close this loophole in units that are yet to ship from the factory.

Finally - Metabones releases the Canon EF to micro 4/3 Speed Booster - Andrew Reid at EOSHD has one!

The adapter that so many Canon shooters have longed for has finally arrived. A powered Speed Booster from Metabones that adapts Canon EF (but not EF-S) lenses to micro 4/3 cameras such as the Panasonic GH4 - with full aperture control and image stabilization. I can't wait to get my hands on one - but until then, I'll have to live vicariously through Andrew's hands on experience with it.

That said, everyone is happy about this except Canon. My theory was that they were paying Metabones to delay the release of this adapter to keep Canon shooters from switching to the GH4 (that's a joke, for all of my literally minded readers). Seriously, though, I'll bet a lot of used Canon DSLRs go up on eBay in the next few days.

Arri hops on the 4K bandwagon with an upcoming firmware upgrade for the Amira

Following close on the heels of yesterday's news on the Sony F5 4K hack, Arriflex has issued a press release announcing an official "4K" UHD upgrade for the 2K Arri Amira (full text below). Of course, since this is Arri, the upgrade will not be free (how much it will cost is yet to be determined).

Interestingly, the release notes that the upgrade is in response to "user feedback". In other words, Amira shooters probably wondered why far less expensive cameras from Blackmagic and Panasonic recorded at higher resolution than their $40,000 cameras. It is also interesting to note that the Amira gets the upgrade and the Alexa does not.

Here's the full text of the release:

(August 26th 2014, Munich) – A new software upgrade for ARRI’s documentary-style AMIRA camera will allow it to record ProRes UHD files, answering the 4K requirements of some productions. The upgrade is expected to be available for purchase at the online ARRI License Shop by the end of 2014.
While widespread adoption of 4K or UHD for broadcast is still a long way off, an increasing number of content owners are becoming concerned that they ought to safeguard the longevity of their programs by ensuring that they will be suitable for UHD transmission, should that become a standard in the future. 
For those productions that do need to generate UHD deliverables, AMIRA will now offer the ability to record all ProRes codecs in Ultra High Definition 3840 x 2160 resolution directly onto the in-camera CFast 2.0 cards, at up to 60 fps. This feature, activated through an affordable software license (and a sensor calibration for existing AMIRAs), comes in response to feedback from AMIRA customers, some of whom have been quizzed about 4K deliverables by clients. It is made possible by the camera’s exceptional image quality, its processing power, and its reprogrammable system architecture.
Whether a production is pursuing a UHD workflow all the way through to distribution, or simply wishes to archive in UHD in order to future-proof itself against industry developments, AMIRA now offers an easy solution that requires no additional processes in postproduction.
The ALEXA/AMIRA sensor has repeatedly proved its ability to deliver outstanding image quality for the 4K or even IMAX theatrical releases of high-end feature films such as Gravity, Maleficent and Iron Man 3. This proves that the ALEXA and AMIRA camera systems are already future-proof and more than suitable for the next generation of distribution formats.
For major feature films, an up-sample to 4K can be carried out after visual effects and other postproduction tasks have been completed at 2K resolution. For certain fast-paced AMIRA productions, however, there may not be the time or resources for such processes in post, which is why a 4K or UHD output direct from the camera has been requested.
AMIRA’s UHD output utilizes the same efficient 1.2x up-sample filter that allows ALEXA’s Open Gate mode to optimize the camera’s image performance for 4K distribution, as well as the same best-in-class sensor pixels. The up-sample to UHD happens in camera, and in real time.
Outputting UHD broadens the distribution options for the superior image quality that has helped make AMIRA, and ALEXA, such a success. The wide, 14+-stop dynamic range remains unaltered, as does the accurate colorimetry, natural skin tones, and organic look and feel. By making that high-quality image data coming out of the sensor compatible with higher spatial resolution formats, the UHD upgrade answers the concerns of certain regions and productions about a 4K future, allowing AMIRA to be used on any project, no matter what deliverables are required.
Markus Duerr, ARRI’s Product Manager for the AMIRA system, says, “Feedback about AMIRA from all over the world has been overwhelmingly positive and it is clear that the camera is already a great success, being used on an amazing variety of challenging productions. Already acclaimed for its phenomenal image quality, ease of use and versatility, the new ProRes UHD output will take these benefits even further, adding value for customers in areas like China, where 4K is a major focus of industry attention.”
Wildlife cinematographer Rolf Steinmann, who was nominated for an Emmy Award this year in recognition of his work with ALEXA on the BBC’s Wild Arabia series, is currently using his AMIRA on a movie for Disney Nature. He comments, "For cameramen like me who own their gear, the UHD upgrade is a great way to stay future-proof. From now on when there's pressure from the production side to deliver UHD, I can continue to work with AMIRA and won't have to compromise on image quality or on the camera's robustness and reliability." 
About ARRI:

The Academy of Motion Picture Arts and Sciences has recognized ARRI’s engineers and their technical contributions with 18 Scientific and Engineering Awards.

In my view, this is just the beginning of the wave of 4K/UHD announcements and press releases we will see in the coming year. Manufacturers from Arri to Canon to Sony will introduce new 4K cameras and upgrade older models. If a camera doesn't record 4K, it will lose a lot of its market appeal. As a result, shooters will start unloading old 1080p and 2K cameras at bargain basement prices. It will be the story of the transition from SD to HD all over again.

This will be great news for entry-level amateur shooters who are looking to buy a 1080p camera in the next few months - but pros and high-end amateurs interested in delivering higher resolution to their clients and audiences may want to seriously consider upgrading - especially since there are reasonably priced cameras with 4K/UHD internal recording from Blackmagic and Panasonic already on the market.
