GH4 4K Fireworks

24.00HzTook the new GH4 to the 119th Sequim Irrigation Festival Fireworks. I thought it would be good to use the Cinema 24p at 4K on the camera. That's right, the camera records at 24 frames per second just like a film motion picture camera. None of this 24.976 stuff to NTSC. Just set the camera to 24.00Hz (CINEMA) in the Setup menu under System Frequency and the camera will only record 24p. Now we really have a motion picture camera.

This is the first 4K test with the new camera that I am publishing. I recorded the footage at 100mbps IPB on to a HoodMan RawSteel 32gig Class 10 U1 SDHC card with no problems. On a 32 gig card the camera estimates that you have about 40minutes of record time.

There will a an article soon explaining the differences in the 4K modes in the GH4. We are in a new exciting world with the GH4.

4K Video of Kenmore Camera on YouTube

4K – it is insane. I cannot even play it back on the screen of late 2013 MacBook Pro Retina. 4K video has more pixels than my screen so I cannot view it in all it's grandeur. I have posted on YouTube at 4K the footage I shot at Kenmore Camera’s Grand Opening on a preproduction GH4. For those of you can view 4K it is there for you to see. The rest of us Will have to view it at lower resolutions.

The GH4 is the first camera that I will own that has more resolution than my computer screen. I have experienced 4K video before using a RED camera. The RED camera files were difficult to use because that camera only shoots RAW so the file sizes are huge.

At 100 Mb per second the GH4 files are much more easy to use. I like that the h264 files are in a QuickTime wrapper in the camera. I had no real trouble editing this footage. Final Cut Pro X is already set for 4K. Your performance on another editor may very. I imported the footage from the SD card and it did not take that long because the file sizes are reasonable. FCPX has smooth playback while editing this footage. I did not add a lot of effects or layers so rendering times were quick. Later I will do some heavier editing to push my editor to see if I have any problems.

Shooting with the GH4 requires a very fast SD card to have the camera continue recording without stopping. It appears that 95 Mb per second cards seem to keep up with the 4K video. These faster cards also make importing the footage faster.

Also I will post some 4K screen grabs from the 4K video in my Flickr Set.
