# 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.

In this example, the video content was generated with a green screen background. This negatively affects the shadow effect, casting a rectangular shadow instead of a shadow that mimics our content.

In this example, the video content was chroma keyed, resulting in a "transparent" background. When exported, this will be pure white. This will allow shadow and reflection effects to work properly.

In this example, an extra tint was applied after chroma keying the content. This tinted color will show as a multiply blend on top of the hologram itself. Content should be properly chroma keyed before applying the tint.

Content should not include busy backgrounds like this one, this will effectively hide the holographic element of the HLD and severely weaken the 3D effect

### 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.
