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.
You can animate properties like Size & FOV using sequencer by tracking your HoloPlay Capture, then tracking the "render camera" element.
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.
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 have a HoloPlay Capture Actor or component in your scene, your sequence will capture a quilt!
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.
There's a second "field of view" variable, ignore this, it doesn't do anything. The variable you want is FOV.
Once you are ready to export you can select the Render button which will open the Render Movie Settings.
3360 x 3360 for the Portrait
8192 x 8192 for the 32" and 65"
These settings will get applied automatically if you select the appropriate device from the Looking Glass Tiling Settings dropdown.
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:
In order to properly capture a you'll need to set compression quality to 100, and resolution to custom and then to one of the standard resolutions for our devices:
