Redis makes no assumptions about the data it stores. The only limitation is that the protocol only accepts strings up to 512 Mb.
Apart from that, Redis stores everything in memory, so you can fill up your RAM pretty quickly with just a few large videos.
Depending on your use case it might be best to just store the media data on disk, and have some metadata stored in Redis.

Keep in mind that this issue tracker should be used for bugs or improvements to the Redis server. For questions like yours please ask on the mailing list or ask in the irc channel #redis on freenode.
