Exporting Quilt Images and Video with Sequencer

For creating videos with the Looking Glass display we’re going to use the Sequencer which is Unreal Engine's built-in cinematic editing tool.

Controlling the HoloPlay Capture via Sequencer:

You can animate properties like Size & FOV using sequencer by tracking your HoloPlay Capture, then tracking the "render camera" element.

1) Add a Level Sequence to your scene

On the toolbar above the Main Viewport in the editor you will find a button that looks like a movie clapper board. Press the down arrow next to it and select Add Level Sequence. This will spawn a Level Sequence in your scene.

2) Enable Quilt Capture

3) Open your Level Sequence

Unlike a normal cinematic sequence you don't need a camera track. In fact you don't even need a track for the HoloPlay Capture actor! As long as you've checked the two options in Step 2 and have a HoloPlay Capture Actor or component in your scene, your sequence will capture a quilt!

Tracking your HoloPlay Capture

First click the Track button with the green plus and choose your HoloPlay Capture, then click the smaller white track button on the HoloPlay Capture track, from there choose "RenderCamera". The Render Camera object will have all of the variables exposed that you can control. The ones you'll probably care the most about are FOV and Size.

4) Open Render Movie Settings

Once you are ready to export you can select the Render button which will open the Render Movie Settings.

5) Capture Movie

In order to properly capture a Quilt you'll need to set compression quality to 100, and resolution to one of the Looking Glass Presets.

6) Compile your image sequence into a video

After you have your image sequence exported you'll need to compile the frames into a video file, preferably mp4 or webm. To do this you can use a variety of tools, a really quick way is to use blender, like shown in step 3 here: https://learn.lookingglassfactory.com/tutorials/blender
