Setting up HDR within Windows

To enable HDR for the Prime Scene Designer Canvas, your Windows Display Settings must be configured to use HDR. The monitor you will be using to display Prime Designer must be a HDR-capable monitor in order to turn on HDR in Windows.

Enable HDR in Windows 10:
Select the Windows Start Button, then select Settings > System > Display.
Choose the HDR-capable display under Rearrange your displays.
Select Windows HD Color settings
Under Display capabilities, check to make sure it says Yes next to Use HDR.
Turn on Use HDR.

Enable HDR in Windows 11:

Select the Windows Start Button, then enter Settings. Select Settings > System > Display.
Choose the HDR-capable display at the top of Display Settings.
Scroll down to HDR under Brightness & Color and switch HDR to On.

Prime Scene Designer HDR canvas setup

Once HDR is set up within Windows, please startup Prime and navigate to Playout. Select Config > Playout Configuration. The Prime Scene Designer Canvas is tied to the first output channel within Playout Configuration. Due to this, please set the first output channel to a Device type that will allow you to select HDR 10 Bit.

HLG and S-Log3 based HDR are not available for use with the Canvas. However, if your first Output Channel is set to HLG or S-Log3, the canvas will automatically use HDR 10 Bit. LUT files are not compatible with HDR or Prime’s Scene Designer Canvas. HLG based channels are the only type of channel which supports LUT files as outlined in the Prime Playout Configuration User Guide.

‎Even if your first output video channel is set to HLG with a selected LUT file, the LUT will Not be applied and displayed on the Canvas itself. It will only be applied to the Playout Video Output Channel itself as the Canvas does not support LUTs.‎
‎When HDR is enabled for the first Playout Video Channel but your monitor does not have HDR enabled within Windows, the Prime Scene Designer Canvas will appear washed out like in this example.

‎Please see the Prime Playout Configuration User Guide for channel setup instructions and further HDR, HLG, and S-Log3 details.

Scene properties

The following scene properties are displayed:

Description: The user may enter a simple description of the scene‎
Keywords: Add metadata to search for scenes
Style: Can be linked to a CAMIO context and changed in LUCI. See Style Sheets for more.
Message Id: Messages recorded from this scene will start recording at the specified location or the next available location. When a message is read, PRIME will read in the base message and fulfill the template with the data from the message.
Channel (On): Recall the scene will play to the defined channel
Layer (On): Recall the scene will be positioned in the defined layer on output
Effect In: When the scene plays use these triggers in the trigger list as the Effect In. Usually it’s just an Action or Condition to effect in
Effect Out: Execute these triggers when the scene transfers from Program to Preview
Layer In: Triggers when a scene in Preview plays to Program replacing another scene in the same layer. This supersedes the “Effect In”.
Layer Out: Triggers when a scene in Program is played off by an incoming scene in the same layer. This supersedes the “Effect Out”.
Preview In: Executes when a scene is loaded into Preview. The Defined “Effect In” will still execute when the scene is played. This is useful for LUCI previews in a CAMIO workflow.
Update Behavior: Only applies when the scene is playing on Output and the same scene (or message based on same) is cued to played next
Update Values: On playback of the cued scene, the cued scene updates the replaceable values of the playing scene without replacing the playing scene from the output
Replace Scene: On playback of cued, the playing scene is fully replaced by the cued scene. Layer In and Layer Out will be used if defined. Otherwise, Effect In and Effect Out will be used.
Auto Priority: An incoming scene takes priority over an outgoing scene. To adjust the priority, uncheck Auto Priority and change the value in the Scene Properties > Render section of the Scene Group. The default is 2000. Auto Priority will override the Z position of multiple scenes in the same channel.
Resolution: Set the resolution format for the scene.
Region of Interest: Set the Region of interest for the scene that can be used in designer to crop; save image and save clip files. (0,0,0,0 for Left, Top, Right and Bottom bounds is fullscreen resolution with no cropping applied).
Size: Reward only text for final size of defined region of interest
Set to Graphics Bounds: Selecting this button will update region of interest values to calculate the utmost bounding edges for top, left, bottom and right of all objects combined in the scene.
Thumbnail: Set the thumbnail that will be used in PRIME’s scene browser.
Use Region of Interest: Enable this to crop the thumbnail to the defined region of interest in the scene
- *This will only be applied to Prime’s scene browser and does not apply to LUCI thumbnails and previews.

Command Sequence

The command sequence allows you to build a list of Trigger items to play out in a sequence:

Adding a Command allows you to choose an item from the Trigger list:

The right Green arrow indicates whether the item, after being executed, will move to the next item in the list. This is called “Follow Through”. Some items, like Action, can ONLY be follow through.

The Command Sequence has its own API and can be controlled by a Condition, A script or from a Control Panel.

C# Script: Scene.CommandSequence.Execute

Condition
