This is an app I made for viewing and recording video of your own content in and augmented reality scene. Content can be 3d models, images, audio and videos that are on your device's storage.
I posted it a while ago but have since improved it and created this video demonstrating its use.

This is an app I've been making with Unity for the past 7 months.
You can load your own content from your device's storage and record it to a video. You could use it to direct your own movie scenes with realtime CGI that you can see as you film it. The video can be saved as an mp4 or uploaded directly to YouTube, twitter etc. within the app.
It's already available on Android https://play.google.com/store/apps/details?id=com.realitytheatres.art
and hopefully on iOS later in the year.
The blue robot dance animation comes included if you run the tutorial.
AR Theatre for android allows you to import an mp4 from your devices storage. It's an app I made. Though it won't work on a blank wall, it'll need some features to track
Recently updated an app I made some time ago. It allows for importing 3D models, images, video and audio from your device's storage.
