In BIGVU, you can overlay your video with images and videos using the Composer.
There are several ways to upload your videos and images:
1. If you are already editing your video in Composer, upload inside the Composer.
2. If you want to prepare for future editing or you want to upload music files (mp4 supported), use Media Library.
Anything you upload, whether on Composer or in Media Library, is saved within BIGVU.
