    Parameters - Video Page

    Active active - Controls if this node is sending out data over the ST2110 device.

    ST2110 Device CHOP st2110devicechop - Since a NIC has one set of settings such as DHCP/IP settings, that is controlled for each device using the ST2110 Device CHOP. This node will use that device to discover available output channels, and use the settings configured in that node for it's operation.

    Device device - Will be populated when the ST2110 Device CHOP is active and configured properly. Select which output channel on the device to use.

    Video Destination IP videodestip - The multicast IP address that the video essence should be sent on.

    Video Source Port videosourceport - The local network port number that the video essence should be sent from. Some devices will auto-select this port.

    Video Destination Port videodestport - The destination network port number that the video essence should be sent to.

    Video Payload Id videopayloadid - The Payload Id number to assign to the RTP packets for the video essence. Usually 96 for video.

    Output Reference White outputreferencewhite - ⊞ - When converting the color values to the Working Color Space for output, this controls how they should be treated with respect to Reference White. If the Working Color Space is the same Reference White, then no adjustment is done. If they are different, then the Reference White level (brightness) of the colors will be adjusted to the range expected by the Output Color Space. For example if the project is set to have a SDR Reference White of 120 nits, and the HDR Reference White is 80 nits, and the project Working Color Space is HDR while the Output Color Space is SDR: then a color of (1, 1, 1), which is 80 nits in the HDR color space, will be converted to be (0.66, 0.66, 0.66), which is 80 nits still in the SDR Output Color Space.
    • Default For Color Space default - Will use either the SDR or the HDR Reference White, based on the color space detected/selected.


    • Standard (SDR) sdr - Will treat the Output Color Space as SDR for it's reference white value.


    • High (HDR) hdr - Will treat the Output Color Space as HDR for it's reference white value.


    Parameters - Common Page

    Output Resolution outputresolution - ⊞ - quickly change the resolution of the TOP's data.
    • Use Input useinput - Uses the input's resolution.
    • Eighth eighth - Multiply the input's resolution by that amount.
    • Quarter quarter - Multiply the input's resolution by that amount.
    • Half half - Multiply the input's resolution by that amount.
    • 2X 2x - Multiply the input's resolution by that amount.
    • 4X 4x - Multiply the input's resolution by that amount.
    • 8X 8x - Multiply the input's resolution by that amount.
    • Fit Resolution fit - Fits the width and height to the resolution given below, while maintaining the aspect ratio.
    • Limit Resolution limit - The width and height are limited to the resolution given below. If one of the dimensions exceeds the given resolution, the width and height will be reduced to fit inside the given limits while maintaining the aspect ratio.
    • Custom Resolution custom - Enables the Resolution parameter below, giving direct control over width and height.

    Resolution resolution - ⊞ - Enabled only when the Resolution parameter is set to Custom Resolution. Some Generators like Constant and Ramp do not use inputs and only use this field to determine their size. The drop down menu on the right provides some commonly used resolutions.
    • W resolutionw -
    • H resolutionh -

    Resolution Menu resmenu - A drop-down menu with some commonly used resolutions.

    Use Global Res Multiplier resmult - Uses the Global Resolution Multiplier found in Edit>Preferences>TOPs. This multiplies all the TOPs resolutions by the set amount. This is handy when working on computers with different hardware specifications. If a project is designed on a desktop workstation with lots of graphics memory, a user on a laptop with only 64MB VRAM can set the Global Resolution Multiplier to a value of half or quarter so it runs at an acceptable speed. By checking this checkbox on, this TOP is affected by the global multiplier.

    Output Aspect outputaspect - ⊞ - Sets the image aspect ratio allowing any textures to be viewed in any size. Watch for unexpected results when compositing TOPs with different aspect ratios. (You can define images with non-square pixels using xres, yres, aspectx, aspecty where xres/yres != aspectx/aspecty.)
    • Use Input useinput - Uses the input's aspect ratio.
    • Resolution resolution - Uses the aspect of the image's defined resolution (ie 512x256 would be 2:1), whereby each pixel is square.
    • Custom Aspect custom - Lets you explicitly define a custom aspect ratio in the Aspect parameter below.

    Aspect aspect - ⊞ - Use when Output Aspect parameter is set to Custom Aspect.
    • Aspect1 aspect1 -
    • Aspect2 aspect2 -

    Aspect Menu armenu - A drop-down menu with some commonly used aspect ratios.

    Input Smoothness inputfiltertype - ⊞ - This controls pixel filtering on the input image of the TOP.
    • Nearest Pixel nearest - Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native Resolution.
    • Interpolate Pixels linear - Uses linear filtering between pixels. This is how you get TOP images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native Resolution.
    • Mipmap Pixels mipmap - Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail.

    Fill Viewer fillmode - ⊞ - Determine how the TOP image is displayed in the viewer.

    NOTE:To get an understanding of how TOPs work with images, you will want to set this to Native Resolution as you lay down TOPs when starting out. This will let you see what is actually happening without any automatic viewer resizing.

    • Use Input useinput - Uses the same Fill Viewer settings as it's input.
    • Fill fill - Stretches the image to fit the edges of the viewer.
    • Fit Horizontal width - Stretches image to fit viewer horizontally.
    • Fit Vertical height - Stretches image to fit viewer vertically.
    • Fit Best best - Stretches or squashes image so no part of image is cropped.
    • Fit Outside outside - Stretches or squashes image so image fills viewer while constraining it's proportions. This often leads to part of image getting cropped by viewer.
    • Native Resolution nativeres - Displays the native resolution of the image in the viewer.

    Viewer Smoothness filtertype - ⊞ - This controls pixel filtering in the viewers.
    • Nearest Pixel nearest - Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native Resolution.
    • Interpolate Pixels linear - Uses linear filtering between pixels. Use this to get TOP images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native Resolution.
    • Mipmap Pixels mipmap - Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail.

    Passes npasses - Duplicates the operation of the TOP the specified number of times. Making this larger than 1 is essentially the same as taking the output from each pass, and passing it into the first input of the node and repeating the process. Other inputs and parameters remain the same for each pass.

    Info CHOP Channels

    Extra Information for the ST2110 Out TOP can be accessed via an Info CHOP.

    Specific ST2110 Out TOP Info Channels

    • connected - 1 if the device is connected/active, 0 if not.


    • frames_sent - The number of video frames sent out.


    • frames_dropped - The number of frames drops from the output. These are output frames that the process failed to provide new data for.
