It's a good idea to upload videos in /webm/ format. In that case Mediagoblin will skip the transcoding step (which can take hours for videos of non-trivial length) and the whole process will be quicker. Transcoding just converts whatever file format you submit into a standard resolution and file type. On your local system you can convert a video to webm with:
#+begin_src bash
ffmpeg -i myvideo.mp4 myvideo.webm
#+end_src
Or if you are moving a video from YouTube to your own site:
#+begin_src bash
youtube-dl -f webm [my_video_url]
#+end_src

When hosting media files you should take into consideration that since anyone on the internet can view your content then this could significantly increase your bandwidth usage and overall strain on the server. If you are hosting anything which might become popular then it's a good idea to set up the Freedombone system on an old laptop rather than something like a Beaglebone Black. However, as small single board computers become more powerful with more RAM and CPU cores being able to stream media to many clients should be far less of a problem.
