The Layer Inspector allows you to set up the following:
Numeric start ID
Per default each layer in the Sequence tab is displayed in gray. Clicking into the gray field opens a color dialog where you can choose a different color. Note that you can also color a container.
Include in Store Active
Uncheck this option to exclude the layer from all Store Active commands.
Mute External Input
Tick this check box to block this layer from any external input, like Art-Net, Input Data from Widget Designer etc.
Tick this check box to mute the audio content of the Layer. Note that the Mute icon in the Device Parameters tab is automatically clicked. Also, the according icon in the Device Tree changes automatically.
Tick this check box to mute the audio content and stop rendering the video content of the Layer. Note that the Mute icon in the Device Parameters tab is automatically clicked. Also, the according icon in the Device Tree changes automatically.
Layer Sizing Mode
Choose from the drop-down list how each layer should handle the aspect ratio of the media files loaded into it. By default the Layer Aspect Ratio is set to "horizontal and vertical fit". Examples are depicted below.
horizontal and vertical fit: the media file will be shown in its original aspect ratio. Regardless whether the file is upright or crosswide, all parts of the media file will be shown, see figure B.
horizontal fit: the media file will be shown in its original aspect ratio. It will fit horizontally into the layer, see figure C.
vertical fit: the media file will be shown in its original aspect ratio. It will fit vertically into the layer, see figure D.
fixed ratio: choose between the ratios 5:4; 4:3; 16:10; 16:9; 1.85:1. The media file will be stretched into the defined aspect ratio when loaded, see figure E.
Media Pixel Size: this is a dynamic mode that depends on the translation factor set up in the Configuration tab > Unit Management. For example, if you have an output with a width resolution of 1920px (and a height resolution of 1080px) the according translation factor is 8.333. Now, the Layer Sizing Mode is based on 8.333 as well. If a 1920x1080px testpattern is assigned to a Layer, it will be displayed fullscreen. A 1024x768px texture will be displayed with a border of 1920-1024=896 and 1080-768=312. In case the Layers of a second Client with a 1024x768px output are set to "Media Pixel Size" as well, the same texture is fullscreen whilst the first testpattern would be cut off.
Render Layer in Pass
The check boxes allow to toggle the Layer's visibility in the available Composition and Output Devices. Per default, the layer is included in the composition pass as it is visible for all available Cameras - it will be part of the so called render target and then be send through the entire output pass. It will be affected by its settings e.g. warp object, keystone or softedge etc.
If you change the default behavior, e.g. uncheck the Camera option(s) and check the Output option(s), the layer is only part of the output pass. It will not be seen by the Camera as it is sent directly to the according Output. In return it will not be affected by all the output settings and can be placed outside the warped / softedged area. This is especially interesting when working with multi-softedged projection(s) and blacklevel compensation is needed. Find more information in the topic Video Processing Pipeline.
The check boxes depend on the number of Cameras / Outputs. A Dual Server has two Cameras, for example, and you may decide whether a layer should be only rendered by one of them. A possible application is working with different outputs for a key & fill scenario.
Examples for different aspect ratios:
Figure A: this is the original media file.
Figure B: Layer Aspect Ratio is set to "Horizontal and Vertical Fit". Regardless whether the file is upright or crosswide, all parts of the file will always be shown in its original aspect ratio.
Figure C: Layer Aspect Ratio is set to "Horizontal Fit", the files aspect ratio is kept and it fits horizontally into the layer.
Figure D: Layer Aspect Ratio is set to "Vertical Fit", the files aspect ratio is kept and it fits vertically into the layer.
Figure E: Layer Aspect Ratio is set to "4:3" and the image is stretched to this aspect ratio.
