GhostFrame FAQ

All questions answered

What is GhostFrame?

GhostFrame is a powerful suite of features for virtual production and XR stages, broadcast, film and live production. GhostFrame makes it possible to simultaneously capture multiple independent images on camera by interleaving multiple frames of different content between each regular video frame. For this to work, the camera is required to run at a high frame rate.

How will this make my LED screen look?

The innovative and patented technology of GhostFrame allows the multiple content feeds for be played out while the human eye sees only one, still allowing the camera to capture each of the desired content frames.

How does GhostFrame affect the pixel capacity of the complete system?

When using GhostFrame Chroma and GhostFrame Track, there is no reduction of system capacity or reduction in how many LED panels can be connected on an Ethernet chain. Furthermore, there is also no burden to your render engine. This is a significant benefit over other systems.

How does GhostFrame affect the bit depth?

As the number of slices increases, the LED panel will dynamically reduce bit depth as needed. Typical bit depth depends on the LED panel but normally is around 16-bit. It is very dependent on the LED panel design, but when using the maximum number of slices, it may reduce bit depth to 12-bit grayscale.  Bit depth is affected equally across all slices. Driver data is always sent as 16-bit, but grayscale clock limitations for increased slices will reduce the effective grayscale bit depth.

Will I experience luminance loss on the screen?

Luminance loss is purely LED panel design dependent, but it won't typically cause the screen output to get visibly dimmer.

 

Which LED panels are supported with GhostFrame

GhostFrame only works in combination with ROE Visual LED panels and Megapixel VR's HELIOS Processing.
ROE Visual Black Marble BM4, Black Pearl BP2 and BP2 V2, Black Quartz BQ3.9 and Ruby RB2.3 all work with GhostFrame.

How multiple source is Multiple Source?

You can actually add 4 different inputs simultaneaously in the system. Of course these inputs need to be synced. This will allow you to have 4 independent video feeds resulting in maximum of 4x4K input.

How do I select what's visible on the screen?

With up to four different inputs you need to be able to select what input is shown on the screen. This is done in the GhostFrame matrix in the HELIOS processor and works as simple as just selecting the content you want to display.
