How to make my video window appear in the appropriate aspect ratio?
The Aspect Ratio of a Video Component can be changed at configuration time or during operation.
At Configuration Phase
The Video Component has a Default Aspect Ratio, but it can also retrieve its Aspect Ratio from the encoded WSS. In the absence of WSS information, the default Aspect Ratio will be used.
To Specify the Default Aspect Ratio:
When configuring a Video Component, the Default Aspect Ratio can be selected as either 4/3 or 16/9.The Default Aspect Ratio is used by the software to determine the maximum size of the Video Component. Note that switching back and forth between the two Aspect Ratios will lead to smaller and smaller Video Components due to the algorithm used.
- Select the Video to configure (if the Video is within a Monitor, right-click on the Monitor and select Unlock Monitor from the popup menu, and then click on the Video, or more directly, ALT-click on the Video).
- Display the "Configuration Panel" (if it is not already displayed) by double-clicking on the Video, by selecting "Configuration Panel" from the "View" menu or by pressing "F5".
- In the "Assign Video Input" section select the "Default Ratio" to use (4/3 or 16/9).
- Click on the "Apply" button.
To retrieve the Aspect Ratio from WSS
Specifying that the Aspect Ratio is changed automatically through the use of WSS allows the Video Component to respond automatically to the input signal content without operator intervention. Note that when automatically changing the Aspect Ratio, the Video Component check the configured Default Aspect Ratio to determine its maximum size.
- From your KEdit open the Layout to modify (select "Open" and "Online" from the "File" menu or press "Ctrl-O" and select the K2 from which you want to modify the Layout).
- Select the Video to configure (if the Video is within a Monitor, right-click on the Monitor and select Unlock Monitor from the popup menu, and then click on the Video, or more directly, ALT-click on the Video).
- Display the "Configuration Panel" (if it is not already displayed) by double-clicking on the Video, by selecting "Configuration Panel" from the "View" menu or by pressing "F5"..
- In the "Assign Video Input" section select "Change aspect ratio automatically (WSS)".
- Click on the "Apply" button to apply the modifications to the selected Video Component.
When the decoded Aspect Ratio changes, the Video Component's size will automatically reflect the new value.
You can assign the modified Layout to a preset. To do so using the Kaleido RCP, press and hold the function key (those keys are located to the top of the device) for at least 6 seconds to associate it with the Layout. Using a keyboard connected to your K2 press the function key (F1 through F10) for at least 6 seconds to associate to the Layout.
During Operation
It is possible to modify the Aspect Ratio of a Video during operation using the RCP or the keyboard. When modifying the Aspect Ratio of a Video during operation the Video Component checks the configured Default Aspect Ratio to know the maximum size it can have.
Using the Kaleido RCP
Using the Kaleido RCP connected to the K2 you will need to select the appropriate Video Component and indicate the modification of the Aspect Ratio.
- Press the "Select" key of your Kaleido RCP. You will see numbers appearing over the Video Components, verifying that you are in selection mode.
- Using the Arrow buttons, navigate to the desired Video Component and press on the "Enter" button to select it. If needed, navigate to other Video Component and select them. To select all the Video Components contained in your Layout press on the "Select" button again.
- Press the "Aspect Ratio" button to toggle the Aspect Ratio from 4:3 to 16:9 and vice-versa.
- To exit the selection press on the "ESC" button.
Using a keyboard connected to the K2
Using the keyboard connected to the K2 you will need to select the appropriate Video Component and indicate the modification of the Aspect Ratio.
- Press the "Tab" key of your keyboard. You will see numbers appearing over the Video Components, verifying that you are in selection mode.
- Using the Arrow keys, navigate to the desired Video Component and press on the "Enter" key to select it. If needed, navigate to other Video Component and select them. To select all the Video Components contained in your Layout press on the "Tab" key again.
- Always on the keyboard, press the "R" key to toggle the Aspect Ratio from 4:3 to 16:9 and vice-versa.
- To exit the selection press on the "Esc" key.
