Hi, http://svn.debian.org/wsvn/debconf-video/talks/?rev=0&sc=0 is the svn repo weburl where we develop our talk to be held at DebConf8. The outline reads atm: The video team, people, hardware and software People We would like to bind up as few people as possible in the video team. Our activity is a service, not a playful hacking thing. Post production takes for ever, if it ever happens. We strive to get as much as possible done instantly. Hardware The hardware should be cheap and light. Commodity hardware is more convenient than specialty hardware. Two non-commodity pieces that we now consider "must have": Scan converter (VGA to DV) and wireless mic. The laptops and the DV cameras can be borrowed by/from participants or the local team. Software The software should be a minimal set of packages running on Debian Stable. Dvswitch fits that bill. TODO Talkback: The camera operators should have headsets, and receive oral instructions from the mixer operator/producer. Tally lights: The cameras should have a red lamp telling everyone (especially the camera operator) when they are "on". Caveats Lighting problems. Good room lighting should provide a comfortable light level and adequate light for cheap cameras, and still not wash out the projector screen. More often than not, this is not the case. Lighting workarounds. Spot light on the speaker, turn off the rest during the talk. Turn the lights on again for the Q&A session, assuming the screen won't be much needed then. Recording the sound from the audience takes some care. We want reactions from the audience to be audible, but general murmur and air condition noise should be cut out. The crowd cam should see _everyone_ in the audience. This may require a tall platform, or (fancy!) a jib arm. *** What the software does * dvsource Grabs video from a DV camera over firewire, and sends it over TCP to the *dvswitch*. Dvswitch may run on a different computer, usually nearby. * dvswitch The heart of the system is dvswitch. * dvsink Receives the output from dvswitch *** Live demo * Show the hardware Laptops Cameras, tripods, firewire Scan converter Switch, ethernet cable Sound mixer * Show the setup Speaker cam, head mic Crowd cam, crowd mic Cabling (gaffa, gaffa, gaffa) * Demonstrate editing Recursive video (gag) Cutaways (let the cam-op frame the shot) Eye direction (when two shots won't intercut well...) Sound level (open and fade out crowd mic) PiP? Text overlays? Disorienting each other and the stream team (gag) "Do you have goatse there?" Comments welcome! I dont get the goatse reference :) regards, Holger
