tests the video quality between the internal recording on the Panasonic GH4 and the Atomos Ninja Star:
There is a weird glitch going on when I have both 4K recorded shots up, I think the Crop that I have in Premiere didn’t want to cooperate, but it shows up at the bottom of the frame. I tried numerous exports to no avail.
I tested the GH4 100Mbps H.264 internal 8Bit vs the Ninja Star 220Mbps ProRes Hq 10Bit, both the Cinema 4K and FHD. I shot with three different settings, but they are in different videos…
It was a very foggy and overcast day, so keep that in mind as you look at the footage.
iDynamic/iResolution is off for all shots. All shots are 0-255 and converted to 16-235 in post. Graded with Lumetri Looks Cinematic 2 in Premiere Pro CC, and steep RGB curve to see what I could get out of the footage.
This test was to see if the 10Bit would make a huge difference, and if 4K scaled to 1080 in post would be better than 4K scaled to 1080 in camera. The Color Profile is called Dragon, as it was found in a RED user forum that tried to match the GH4 with a RED Dragon. I do like it, but I need to test with skin tones as the White Balance 2 Amber and 2 Green could throw things off.
I have to say that the Ninja Star footage is considerably better. I had all of the settings the same, and all of the grading is set it exactly the same, but the footage out of the Ninja Star just came out with a better range of light, and color. It may seem slight on some shots, but it’s clear as day on the last shot. I will say that my histogram read that the image was fine, but the Ninja seemed to be brighter than what the camera was reporting. So that is something to watch out for, my Cine-D footage definitely came out over exposed.
The biggest difference between the Ninja 4K footage downscaled to 1080, and the GH4 4K footage, is that I can scale into the GH4 footage and keep the quality and clarity, so when the need arises for that I will use the GH4 internal, but every other situation I will definitely prefer the Ninja Star for the great quality image.
The tests were conducted in three settings:
