🎬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 Looking Glass Capture via Sequencer:

You can animate properties like Size & FOV using sequencer by tracking your Looking Glass 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) 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 Looking Glass Capture actor! As long as you have a Looking Glass Capture Actor or component in your scene, your sequence will capture a quilt!

Tracking your Looking Glass Capture

First click the Track button with the green plus and choose your Looking Glass Capture, then click the smaller white track button on the Looking Glass 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 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 custom and then to one of the standard resolutions for our devices:

• 4092 x 4092 for Looking Glass Go

• 5995 x 6000 for the Looking Glass 16" (Portrait) and 5999 x 5999 for the Looking Glass 16" (Landscape)

• 7680 x 4320 for the Looking Glass 27" (both landscape and portrait orientation)

• 8192 x 8192 for the Looking Glass 32" and Looking Glass 65"

These settings will get applied automatically if you select the appropriate device from the Looking Glass Tiling Settings dropdown.

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 please follow the guide here:
