Video Inputs

Please note that this is a BETA version of the document. All information presented is correct but we are working on improving the details.


Video inputs can be Live Feed (camera input) or pre-recorded footage. Based on this we define 2 main groups of video inputs. They are

  • External video inputs, 
  • Internal video inputs.

External video inputs

External video inputs serve the video signal from outside of the computer by some device. The device can be a camera, external media player, etc. In this case, how the signal arrives at the computer matters. 

SDI Consider this industrial standard It is widely used but it deals only with protocol resolutions. Because of this limitation, It is less used with LED walls. 

To make a computer have an SDI input it needs a capture card.

IMPORTANT: Before buying your capture card, ensure it is compatible with Aximmetry. You can check the list of compatible capture cards: Interfaces.
You may also ensure that your capture card supports the resolution you want to work with.

NDI inputs

You can use NDI inputs in Aximmetry. To use it configure the NDI in your computer then Aximmetry will recognize it as a video input. More info about NDI Setup.

HDMI / Display Port

High-Definition Multimedia Interface (HDMI) is a proprietary audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data. HDMI is a digital replacement for analog video standards.

DisplayPort (DP) is a digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA).

You also need a capture card for these.

Internal Video Inputs

Internal video inputs are:

  • Pre-recorded videos
  • Images
  • Graphical textures

The commonality in these inputs is that they are already on your computer. To use them simply drag the file and drop it in your Flow Editor. They will appear like new modules.

Supported files, encoders, and decoders
