Do the MK devices support 6K or 8K videos?
No, the MK devices are not compatible with 6K or 8K videos. Please refer to the compatible
media specifications.
No, the Fulldome format is not supported by the MK devices. However, the MK360 can be
used in a dome and will correctly display industry standard 360° videos. Please refer to the compatible
media specifications.
Can the MK devices display content from Youtube360, Facebook360 or Vimeo360?
No, the MK360 cannot display videos from Youtube360, Facebook360 or Vimeo 360. These platforms’ 360° video players allow for a Field of View ranging from 30° to 120°, whereas the MK360’s Field of View can reach 270°. The MK360 requires access to the complete equirectangular image in order to display correctly and allow for user interaction. It is possible to use the
MXMirror Add-on and adapt the warping preset in order to display videos from third party platforms directly, but there will be some image deformation.
No, the MK devices do not support these types of applications out of the box. However, some of those are under development and may be integrated to some extent depending on the use case. Please contact us to evaluate your project together.
Are the MK devices compatible with third party hardware such as game controllers or VR lighthouses?
No, the MK devices are controlled only through the MXControl interface or the iOS App. However, those interfaces can be customised and the MK devices can also receive messages in OSC protocol over local network. Please contact us to evaluate your project together.
Do the MK devices support Spatial / 3D Audio?
No, the MK devices do not currently support Spatial / 3D Audio. This feature is in R&D phase, we hope to have news soon. In the meantime, please refer to the other
audio options.
What is the size of the pixel displayed by the MK360?
The pixel size will depend on the distance from the MK360 to the projection wall.
It can be approximately calculated with the following formula:
For:
- p = pixel size in mm
- r = distance from the projector lens to the projection surface in m
Then:
- p = π*r/1.92 = ~ r*1.6362
For example, if the MK360 is placed at 3 m from the wall, the pixel size will be approximately 5 mm.
If it is placed at 5 m, the pixel size will be approximately 8 mm.
etc.
Can the MK360 be hung to the wall or ceiling for floor projection?
No, the MK360 is not designed to be hung from the wall or ceiling:
- The image is very distorted, the horizon is curved.
- The MK360 weighs 32 Kg.
- Hanging from the ceiling prevents from projecting on the ceiling.
- Hanging from the ceiling causes shadow issues.
Some of the videos I upload to the MK devices do not loop, how can I solve this?
Some videos have incorrect or unavailable metadata, which makes them unreadable by the MK360 player. There are a number of solutions to this:
- Inject metadata using a 360 video metadata injector such as Spatial Media Metadata Injector.
- Import the video to a new composition in After Effects, and export using the default 360 video settings in the Media Encoder.
- Import the video to Adobe Premiere, navigate to Clip > Modify > Interpret footage, and define the following VR Properties:
- Projection: Equirectangular
- Design: Monoscopic
- Horizontal view: 360°
- Vertical view: 180°
I sometimes see a red or blue halo when zooming in a high contrast zone of a static image, is this normal?
Yes, chromatic aberrations are an inevitable phenomenon of any lens array. The MK deives include state of the art optics, and has been tuned to reduce this effect at maximum, but it may become visible in a high contrast portion of a static image, especially in the peripheral zones of the projection.
Can I use the MK360 for video-mapping?
No, the MK360 is not designed for video-mapping of an equirectangular image to the specific geometry of an indoor space. The equirectangular image fixes depth in all directions, which makes it close to impossible to separate and map a specific plane or element without distorting the remaining image.
The MK360 provides a correct perspective to the virtual environment from a sweet spot of 1-2m around the device, independent from the geometry of the space. It allows to display any industry standard equirectangular image, without requiring post-production, into any indoor space with controlled lighting. This is very different from a site-specific multi-projector mapping setup requiring one-use content.
