The raw files outputted by the Bublcam are JPEG and H.264 compressed MP4 for photo and video respectively. The raw file comes off the microSD card in a "multiplex" format, which is each of the fisheye views from the 4 lenses combined into a quadrant.
Example:
You can also access the raw file in an equirectangular format, which is the full sphere projected out on to a flattened map.
Example:
Typically the file storage required is 1 MB/second for video (up to 10 MB/second in very low light) and 5-8 MB per photo. So for example, a 32GB card could hold 32000 MB / 3600 sec = 8.88 hours. For photos, 32000 MB / 8 MB = 4000 photos.
