I am actually not the only one who was thinking about how it would be to have video content on STEEMit as well.
I don't have enough knowledge about how it all works here and the technical background, to be able to say or say not if it would be even possible.
Video content actually needs a lot more storage space and the same would be the case for the blockchain.
I believe every post is a new "block" but thats pure speculation. So lets imagine videos would be added, not only the block count but also the size of the already about 1 Gb big blockchain would prolly increase dramatically.
You can try that yourself - write some Text into a txt, rtf or whatever kind of file and compare it to a video. Even with a format like xvid or h.264 you will have a couple of Mb for a video of just a few minutes. While you could type quiet a few books into a file to even break the 1 Mb border.
Surely there are ways to solve these issues and maybe somebody will get the idea while he's reading this post.
Anyways - hope dies last and steemit is just starting, so there will definitly be a lot more amazing things that we can't even imagine now.
Only time will tell !
PS A big thanks going to user ahnaja for his effort and work to bring the idea to some image, and allowing me to share them !
