# Preparing content

Looking Glass Hololuminescent displays are composed of two parts — a static holographic embedding, and a high-resolution display. 

### Aspect Ratio and Resolution

For the best results with our templates, we recommend first setting your content to be 9:16 aspect ratio, and 2160 x 3840 resolution. This will allow you to more easily drop the content into our Adobe Premiere Pro or After Effects templates. 

### Handling Color

The content on the display effectively acts as a layer inside the hologram. Color wise, this is similar to a "multiply" blend mode. Pure white will act as effectively invisible since the existing color from the hologram would be multiplied by 1, resulting in the same value. 

This multiply effect means that content should be setup in a few specific ways. 

* Content should have a white or solid background. 
* Content should stand out from the background color if one is present. 
* In general, for use with the templates we provide, your content should be masked or chroma-keyed for best use with the shadow and reflection effects.

### Applying Chroma Key effects

Video can be chroma keyed in a variety of ways using many programs. We've found that the `ultra key` effect in Adobe Premiere is a great "one click" solution for quickly applying a chroma key effect. \
\
Chroma effects can also be applied in other video editing tools like Adobe After Effects, Davinci Resolve or Final Cut Pro.&#x20;
