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.

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

In order for sequencer to render to a quilt you need to check the "Play in quilt mode" and the "Lock in main viewport" options. If these options are unchecked sequencer will only render one view.

3) Create a New Sequence

Create a new Level Sequence by clicking on the cinematics toolbar button, and then selecting "add 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, your sequence will capture a quilt! In this sequence here we're controlling the position of the HoloPlay Capture Actor so it follows the dancer around the stage, as well as controlling the dancer's animation and some of the lighting.

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. Set any other export settings as desired and click the “Capture Movie” button. This will output your movie to the specified location.

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:
