I wanted to let you know that I extended youtube-dl [1] to allow upload to Wikimedia Commons (or any MediaWiki).
Nice! YouTube can be a very useful source, I've imported several thousands videos to archive.org on behalf of emijrp with his https://code.google.com/p/emijrp/source/browse/trunk/scrapers/youtube2internetarchive.py In that case it's faster because the video conversion is done by archive.org. I don't know if such scripts should be coordinated in some way.
