Use the Video Input: Live Input panel to configure channels utilizing external sources. The left hand pane defines the number of usable channels and their type. Depending on the video hardware you're using, the available types are:

  • SDI

  • IP (SMPTE ST 2110 or ST 2022-6)

  • RTP

  • NDI (Viz and Matrox implementations)

  • Various Shared Memory inputs

Information: The number of usable channels depends mainly on the installed video hardware.

Live Input Properties: Type SDI

  • Video System: Either the required resolution or Auto to use the configured output resolution. In case of a video wall setup (full screen or custom resolution), Auto falls back to 1080i and must be reconfigured if a different resolution is required.

  • Colorimetry: This setting is only relevant for HDR workflows and available for resolutions from 1080p upwards. Available options are:

    • ITUR_BT_709

    • ITUR_BT_2020

    • ITUR_BT_2100_HLG

  • Bits per channel: Defines how many bits per channel are processed for an input.

    Note: Bits per channel is not supported on SD channels.

  • Video Settings

    • Contains Alpha: Enables alpha for this input. Only available on connectors that have an associated alpha connector.

    • Delay DVE: Sets DVE Delay of video when used as DVE.

    • Delay Texture: Sets texture Delay of video when used as Texture.

  • Audio Settings

    • Enable Audio: Toggles audio for this channel. When set to Inactive, audio is disabled. Default value is Active.

    • Audio Channels: Defines the number of Audio Tracks to be used on the channel. The number of available track configurations is dependent on the Video hardware being used.

    • Delay DVE: Sets the number of frames the audio clip should be delayed in DVE mode before it can be mixed to the output. Default value is 4.

    • Delay Texture: Sets the number of frames the audio clip should be delayed in texture mode before it can be mixed to the output. Default value is 4.

  • VBI Settings

    • Enable VBI: Defines whether VBI should be used for this channel. Set to Active or Inactive. Default mode is Inactive.

    • Delay DVE: Sets the number of frames VBI should be delayed before the clip can be used in DVE mode. Default value is 0 (Off).

    • Delay Texture: Sets the number of frames VBI should be delayed before the clip can be used in texture mode. Default value is 1.

  • Source Connector: Replaces Map To Viz Channel and assigns the selected physical connector to that channel.

  • Connector Settings

    • 3G Level B: Toggles the Level B on that connector if configured to 1080p or higher.

    • Allow Super Black: Toggles super black on this connector.

    • Allow Super White: Toggles super white on this connector.

    • Chroma Clipping: Toggles chroma clipping on this connector.

Live Input Properties: Type IP

  • Video System: Either the required resolution or Auto to use the configured output resolution. In case of a video wall setup (full screen or custom resolution), Auto falls back to 1080i and must be reconfigured if a different resolution is required.

    • ITUR_BT_709

    • ITUR_BT_2020

    • ITUR_BT_2100_HLG

  • Bits per channel: Defines how many bits per channel are processed for an input. This is not supported on SD channels!

  • Video Settings

    • Delay DVE: Sets DVE Delay of video when used as DVE.

    • Delay Texture: Sets texture Delay of video when used as Texture.

  • Audio Settings

    • Enable Audio: Toggles audio for this channel. When set to Inactive, audio is disabled. Default value is Active.

    • Audio Channels: Defines the number of Audio Tracks to be used on the channel. The number of available track configurations is dependent on the used Video hardware.

    • Delay DVE: Sets the number of frames the audio clip should be delayed in DVE mode before it can be mixed to the output. Default value is 4.

    • Delay Texture: Sets the number of frames the audio clip should be delayed in texture mode before it can be mixed to the output. Default value is 4.

  • VBI Settings

    • Enable VBI: Defines whether VBI should be used for this channel. Set to Active or Inactive. Default mode is Inactive.

    • Delay DVE: Sets the number of frames VBI should be delayed, before the clip can be used, in DVE mode. Default value is 0 (Off).

    • Delay Texture: Sets the number of frames VBI should be delayed, before the clip can be used, in texture mode. Default value is 1.

  • Source Connector: Replaces Map To Viz Channel and assigns the selected physical connector to that channel.

  • Connector Settings

    • Allow Super Black: Toggles super black on this connector.

    • Allow Super White: Toggles super white on this connector.

    • Chroma Clipping: Toggles chroma clipping on this connector.

Live Input Properties: Type RTP

  • Video System: Either the required resolution or Auto to use the configured output resolution. In case of a video wall setup (full screen or custom resolution), Auto falls back to 1080i and must be reconfigured if a different resolution is required.

  • Stream Settings

    • Access Unit Aligned Input: If true, the user application provides the decoder with data that is aligned on an access unit. Use if there are artifacts in input due to Open GOP.

    • Disable AV Sync: Disables AV Sync. When there is no audio in the stream, this must be manually set to true.

    • Nic Address: NIC that is receiving the stream.

    • Src Udp Port: Source port only used for RTSP. Must be different for every active RTPS stream.

    • Url: URL of the stream in the format [protocol]://@ip:port. Possible protocol values are RTP, RTSP, RTMP, UDP, and SRT (e.g. udp://@239.0.1.10:50202).

    • Use SW Decoding: Forces the use of Software Decoding even if M264 is available.

Live Input Properties: Type NDI

  • Video System: Either the required resolution or Auto to use the configured output resolution. In case of a video wall setup (full screen or custom resolution), Auto falls back to 1080i and must be reconfigured if a different resolution is required.

  • Ndi Settings

    • Source: The URL of the NDI source to be used.

Live Input Properties: Type SHM

  • Video System: Either the required resolution or Auto to use the configured output resolution. In case of a video wall setup (full screen or custom resolution), Auto falls back to 1080i and must be reconfigured if a different resolution is required.
