Leo Lapworth comments in "For speakers at Perl conferences" that you should record your own talks at conferences, because organisers cannot be trusted to release the videos they take of you.
I wholeheartedly agree. I've spoken at numerous conferences, including several large ones, and only in about 10-20% of cases have the videos of me EVER appeared.
I'm amazed that conference organisers can put in so much effort into recording (dozens of tapes, multiple cameras, multiple operators) and then never produce anything as a result.
The only time I'm aware of that a full talk of mine has appeared online was at a Linux.conf.au, who had a dedicated video team of eight people.
Where is all this footage, and why does it never get processed? Why even bother recording it? If you don't have time, send me the raw tape of my own talk and I will do it myself if needed.
YAPC::NA? You listening?
