4K Panasonic VariCam 35 vs 3.2K Arri Alexa

4K Panasonic VariCam 35

3.2K Arriflex Alexa

Over the last few years, as 4K (and higher) resolution digital cinema cameras from other manufacturers have flooded the marketplace, Arri has steadfastly (some might say stubbornly) resisted giving its cameras the ability to record at resolutions higher than 2K.

In answer to a question at IBC 2012 on when there would be a 4K version of Alexa, for example, camera system product manager Marc Shipman-Mueller said  "...there is just not an urgent need for it...".

Suddenly however, the need must have suddenly become more "urgent" - because Arri has, in quick succession, announced UHD ProRes for Amira (August 2014) and 3.2K ProRes for Alexa (February 2015).

Perhaps coincidentally, the Amira upgrade was announced a few weeks before the new Panasonic VariCam 35 started shipping.  This is a camera that Panasonic seems to have aimed squarely at Arri.  With its 14+ stops of advertised dynamic range and true 4K 120fps ProRes recording, DPs are getting results like these:


 


 





For more examples of the stunning image quality this camera can produce - especially at its "dual native" ISOs of 800 and 5000, please join the new Panasonic VariCam 35 community I moderate over on Vimeo.

And if you're in the market for a high end 4K, 14+ stop cinema camera that can record 2K and 4K simultaneously, features slow motion at up to 120fps and a native ISO of 5000, you can buy or finance the VariCam 35 at Omega Broadcast for $55K.

As always, even if you're not in the market for a VariCam or an Alexa, please shop using the links above or the displays below and in the margins. It won't cost you anything extra, and it will help to keep these 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.

ALL_files_4.11

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.
