Long time Aximmetry Broadcast DE version user - feature question, VS competitor software

Hi:

First, I love Aximmetry and have used it for some time now.

However, I have received some questions from some folks who are wanting to use my studio for some production work I would do for them (music videos using my green screen stages), and they are trying to compare my capabilities to another Los Angeles studio, which uses the Zero Density software modules.

The main question they ask is based on this:

-Reality Keyer software- Zero Density claims: "Reality Keyer is the world’s first and only real-time image based keyer that works on GPU. Reality Keyer provides spectacular results for keying of contact shadows, transparent objects and sub-pixel details like hair. Reality Keyer can work also with 4:4:4 RGB camera sources. The keyer also supports 3D masks for “force-fill” and “spill bypass” buffers besides garbage mask".

What thoughts and information do you have to 'counter' the Zero Density claims? I did attend a demo and it does work well.

Thanks,

Gary

The Zero Density keyer might have been the first, but it’s certainly not the only real-time image based keyer that runs on the GPU. Seems like pretty old marketing copy from Zero Density. Aximmetry also has a 3D clean plate since the latest version. You can create those additional 3D masks if you really need them, but it seems completely irrelevant for music video production. The Force fill and spill bypass is used when you have physical, static set elements that contain green, so it’s more of a “broadcast TV-studio” feature. I’m not aware of any 4K 4:4:4 cameras, but I’m sure they exist in the highest tiers. Aximmetry would have to confirm if the keyer works in 4:4:4, but it is much more important with 1080p signals.

As for the keying quality, I’d say they’re pretty comparable. I’d give Aximmetry a slight quality edge on most aspects. Zero Density might have slightly better contact shadows, at the expense of creating a dark “halo” outline around the subject as well as having less effective spill suppression. Zero Density also lacks the Light Wrap functionality, which is essential for getting a good blend between foreground/background.

I see a lot of people setting up the Aximmetry keyer completely wrong, with bad quality keying and missing shadows as a result. Used correctly, with a properly lit screen and calibrated camera, you should get a fantastic key in Aximmetry.

Hi,

Just to confirm, yes Aximmetry's keyer works with 4:4:4 RGB.
However, as TwentyStudios said, 4:4:4 is not common. And it is not just that the cameras don't support it. It is also not supported by many of the SDI capture cards.

Warmest regards,
