After downloading videos, Nintendo Video stores them on the SD card. However, it's not yet known how the data is stored. Videos are somehow stored in [[Extdata]].
After downloading videos, Nintendo Video stores them on the SD card. Videos with the decrypted SpotPass payload are stored in [[Extdata]]. [https://gist.github.com/bef27e4a60cdb472c359 Metadata] is stored in cleartext in the decrypted extdata - the actual video might be encrypted(unknown), there's no magic number/fourcc in the decrypted extdata for the video. Region info is presumably stored in this metadata somewhere.

File format used for storing videos is not yet known either. Both videos that were available at 18th of July 2011 contained string "boss" in the first four bytes, which leads me to believe this is a [http://en.wikipedia.org/wiki/Magic_number_(programming)#Magic_numbers_in_files "magic number"] used to identify this type of file.

This header and the crypto used for the payload following it is presumably the [[SpotPass]] content encapsulation format.

It appears that this file format is big-endian, unlike [[CXI]].

Data following the header is most likely encrypted using a region-specific key. The video codec used is unknown.
Data following the header is encrypted, the CTR used is likely based on metadata in the header.(like the timestamp) Since [http://wiibrew.org/wiki/WiiConnect24/WC24_Content WC24] content was signed, it's likely SpotPass content is signed as well. The video codec used is unknown. Region info is stored the decrypted SpotPass crypto layer, see above SD section.
