Video Input: Stream Input

Use the Video Input: Stream Input Panel to configure available IP stream input channels. The number of available IP Stream input channels is set in Video Input.

Stream Input Properties

  • Map to VizChannel: Sets which video in channel is mapped onto this Matrox video in channel. The drop-down gives a choice between the available channels. Only the channels not already taken are shown.

    • Unused: Do not use this Matrox channel for video input

    • Video <1 to 8>: Captures input and makes it available in Video1.

  • ProcAmp Properties

    • Brightness: Sets the relative offset on the luminance component of the incoming video (min./max. values are dynamic and determined by the hardware). Default value is 0 (Off).

    • Lumagain: Sets the gain on the luminance component of the incoming video (min./max. values are dynamic and determined by the hardware). Default value is 0 (Off).

    • Hue: Sets the color shift on the chrominance component of the incoming video (min./max. values are dynamic and determined by the hardware). Default value is 0 (Off).

    • Saturation: Sets the gain on the chrominance component of the incoming video (min./max. values are dynamic and determined by the hardware). Default value is 1 (On).

  • Fill Properties

    • Allow Super Black: Determines whether or not to clip an output video signal that is under 7.5 IRE units. Default mode is Inactive.

    • Allow Super White: Determines whether or not to clip an output video signal that is over 100 IRE units. Default mode is Inactive. The colorimetry tables for SD (ITUR-BT 601) and HD (ITUR-BT 709) define a color conversion from YUV with the range of 16-235 to RGB with the range of 0-255. Values above 235 are Super White and values below 16 are Super Black. As Super White and Super Black pixels are outside the range of 1-byte RGB, these pixels are clamped to the normal 16-235 YUV range when used in a texture.

    • Allow Chroma Clipping: Determines whether or not to clip over-saturated chroma levels in the active portion of the output video signal. Default mode is Inactive.

  • Key

    • Contains Alpha: Enables/disables playback of clips with alpha.

    • Key Apply Offset:

    • Key Upscale Luma:

    • Key Invert Luma:

    • Shaped: Defines whether the fill from this channel, when the channel is used in DVE mode, should be interpreted as shaped video during DVE compositing. Default value is Inactive.

  • Video

    • Manager Size:

    • Streaming Size:

    • Pipeline Size: Defines the size of the input queue. Default value is 8.

    • Texturemanager size: Sets Pre-allocated texture buffer size, in frames.

    • Video Delay DVE: Sets DVE video delay when used as DVE.

    • Video Delay Texture: Sets texture video delay when used as Texture.

    • Repeat Mode: Determines the behavior of the IP stream input in case of capture drops. Options:

      • None: Does not repeat. Input goes black.

      • Field: Repeats the last field.

    • 3G Level B: Activates Level B for 3G mode in 1080p50/60/60M. Default mode is Level A.

  • VBI

    • VBI: Defines whether VBI should be used for this channel. Default mode is Inactive.

    • Start Line: Defines at which line on the input the VBI section starts. Default value is 0 (Off). The minimum VBI values are (as for VideoOut):

      • NTSC: 7

      • PAL: 6

      • 720p: 7

      • 1080i: 6

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

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

  • Audio

    • Audio: When activated, this setting enables audio for this channel. When inactive, audio is disabled. Default value is Activate.

      • Channels: Sets the number of audio channels to capture (see also Audio in Viz). Default number of channels are 2. Available channel options for AES on X.mio are: None, 1, 2, and 4. For AES on X.mio2/X.mio2 Plus and for Embedded the channel options are: None, 1, 2, 4, 8, and 16.

    • 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.
