Inputs are the sources from which all content is imported or captured into Composer. Inputs can be static images, video clips, live video feeds (via SDI, NDI or RTMP), or Web Pages.

There is no limitation on how many inputs you can add as long as your workstation/server has enough CPU & GPU resources to manage the load. It might be valuable to know that capture sources often require more resources than still images and images. UHD sources require more resources than SD sources.

Inputs can be reused in any number of scenes. If the input is a video clip or a live source, all input instances will be played back in sync.

Working with inputs

To add an input, use the Add Input dropdown. To add a scene, use the Add Scene button.

The Collapse all button will collapse all expanded inputs.

To change the title name of an input, double-click on the title name of the input.

Use the yellow up/down arrow to collapse/expand the input.

To rearrange the order of the inputs, use drag-and-drop (left mouse button).

Right-click on the input to access actions.

To use an input in a scene, select the scene (in the scene layer view) and either right-click on the input and select "Add to scene" or drag the item to the scene layer area.

To copy the thumbnail image to the clipboard, right-click on the image and select "Copy image".

To delete an item, select the item's name (first row) and press the DELETE key or right-click and select "Delete".

Duplicate scene can only be used on a Scene input. It will duplicate the Scene containing all Scene layers, Operators and Targets.

Open location in Explorer…, will open up a Windows Explorer window where the media file is located on the computer.

If you have used an input in one or more scene layers and want to rename all those instances to the same name as the input, you can use the "Rename all instances" function in the right-click menu.

Inputs: Preview thumbnail

Scenes, and some input types, have a preview feature that displays a thumbnail image. For items supporting preview, the preview image will be displayed at the top of the Inputs & Scenes tab:

The thumbnail is updated when selecting the input or scene.

Available input types

Input types are categorized into five different categories:

• Device capture - video capture devices

• Dynamic content inputs - web page content

• Media file inputs - video clips and still images

• Network inputs - Network video sources, NDI or RTMP input

• Text and Shapes- Create a shape or a text input

As Composer is a plug-in-based system, you might find additional categories and input types. The components described in this guide are the standard components.

Listing input option

There are two ways of listing the inputs, as a list (default) or grouped by media types. The “Group source media by type” is enabled in the Settings window.

Customized inputs

As Composer is a plug-in-based architecture, custom inputs can be designed and developed (by RealSprint). Customized inputs can include different capture cards, IP-based video feeds, etc.
