Software

Here is a list of software you can use to prepare your screencast.

IRC (with ERC)

For a bare bones ERC setup for participating in EmacsConf as a speaker, add the following to your init file. Then, either mark the whole region and do M-x eval-region RET, or alternatively restart your Emacs. Finally, do M-x erc-tls RET to start ERC.

(require 'erc)
(setq erc-server "irc.freenode.net"
      erc-port 6697
      erc-nick "your-nick"
      erc-autojoin-channels-alist
      '(("freenode.net"
         "#emacsconf"
         "#emacsconf-questions"
         ;; "#emacsconf-org"
         "#emacsconf-accessible")))

Personal tips

Damien Cassou

To ease my work, I wrote screencasting.el to start 3 processes simultaneously: showkeys, ffmpeg for audio and ffmpeg for video.
