## Creative guidelines <a href="#creative-guidelines" id="creative-guidelines"></a>

Any video tool can be used to create content — from digital content creation (DCC) apps like Blender and C4D to generative AI tools like Kling and Veo. Real-time applications are also supported with the HLD — simply run the application on a computer or iPad that can connect to the HLD via HDMI or DP, and ensure your content is created following our guidelines.

See our creative guidelines for instructions on how to frame [people/characters](https://hlddocs.lookingglassfactory.com/creative-guidelines/characters) and [products](https://hlddocs.lookingglassfactory.com/creative-guidelines/products) in the HLD and recreate this setup in your tool of choice.

For step-by-step tutorials for tools like Premiere Pro, After Effects, and Blender, see our [Content Guides](https://hlddocs.lookingglassfactory.com/#content-guides) below.

## Creating, reviewing, and preparing content <a href="#creating-reviewing-and-preparing-content" id="creating-reviewing-and-preparing-content"></a>

Once you have a video, still image, or supported 3D asset, open it in the browser-based [**HLD Author**](https://hlddocs.lookingglassfactory.com/apps-and-tools/hld-author).

HLD Author lets you:

* Adjust framing, rotation, chroma key, shadows, lighting, and media-specific effects
* Create animated or depth-treated output from still images and render supported 3D media
* Preview your content on a simulated Hololuminescent Display
* Export the correct MP4 for the included [HLD Demo Media Player](https://hlddocs.lookingglassfactory.com/managing-content/using-the-demo-media-player), BrightSign, or standard portrait-video playback

This is the easiest way to create or refine HLD-ready content and confirm framing, depth, and orientation before deployment.

## Deploying content <a href="#deploying-content" id="deploying-content"></a>

If your content has been generated and reviewed in [HLD Author](https://hlddocs.lookingglassfactory.com/apps-and-tools/hld-author), and you now want to set up playback on hardware, see these guides:

* Use the [Demo Media Player](https://hlddocs.lookingglassfactory.com/managing-content/using-the-demo-media-player) for simple, bundled playback
* Convert the included Demo Media Player into a full digital signage solution with [Yodeck](https://hlddocs.lookingglassfactory.com/managing-content/yodeck-digital-signage-player)
* Use [BrightSign](https://hlddocs.lookingglassfactory.com/managing-content/brightsign-digital-signage-player) for long-term digital signage installations
