More on video recordings
No idea why the anonymous poster did not approve my long comment for his post, having allowed another three comments after mine, so I copy my reply here.
http://yapc.tv is another great start :-)
Seriously (why did you post anonymously?), every small step in recording conference video is easy. All together it is a pain in ass for the organises.
1. Cameras are cheap indeed. In Riga we had a few HD camera that cost less that 200 €. Transporting cameras with tripods is a hassle (OK, I admit that most organisers really live in the city where the conference takes place, and this is not a problem).
2. You need a dedicated cameramen for each camera (thus, three of four additional persons in the stuff). One of the cameras in Riga was stolen. You'd better pay these cameramen and do not ask the attendees as it is difficult for them to sit the whole day in one room.
3. Post processing is another pain in ass. It's not simply cut the talk from the recording and upload it on YouTube. You also need to find the talk title, speaker's name, maybe attach a link for the slides. Links/embedding to the conference site are desired too.
4. Sound. The only way you can cheat and record sound using camera's microphone is a recording in the room with sound amplifiers. Sounds is recorded OK-ish in this case (see http://yapceurope.lv/ye2011/talk/3531 for an example of such recording). Would you like to have better sound, especially in the room which has no amplifiers, be so kind to run around the speaker before he start talking. Barely that means that we need another stuff guy in each room (he/she may also serve a time keeper).
5. Screen capture. Extremely great technique to record video that is displayed on the big screen. Extremely difficult to implement at YAPCs with very few exceptions speakers demonstrate their talks from their own laptops.
6. Permissions from the speakers. Well, not that big problem, and you've got three categories here. a) those who ignore your requests, b) those who agree immediately, c) those who would only agree if they see the video recordings first (which means that you may do all the above with no guarantee that you will be able to publish that).
7. Money-wise. Vimeo PRO account, or a YouTube account, or hosting for the site are not expensive. Time to prepare all above is quite costly.
I have lots of video files archived in my disks at home since 2005, and I have no idea of when this will be (if ever) published. Also keep in mind that it is very easy to receive messages (both public and private) that like "you did a terrible mistake/fucked up/you are idiot", after which you feel that it is just insane to continue volunteering.
8. Together with that you may encounter a speaker who thinks he tells something secret and turn your camera off (here you are: https://blogs.perl.org/users/andrew_shitov/2011/11/lets-say-no-to-no.html). Upd. Ha-ha, there are more comments at that old topic added by the newsmaker a few months later.
Anyway, saying for this year's conference in Kiev, we either will not record at all, or will do the recordings with no guarantee to publish, or will invite a third party. In the latter case we need just to find another 5000 € for that to be done. So simple.
