Simple question. What do you edit your videos with? I use a Mac only software, Screeny, to both edit and record my videos.
I'm not a caster, but for videos I use Fraps+Windows Movie Maker if I want things to be quick and simple. Dxtory+Vegas Pro if I want to be able to separate audiostreams(with dxtory you can record teamspeak/skype/etc separately from the game, Vegas Pro allows you to edit them separately too, lotta work though). Not sure if those programs have Mac versions.
Video recording: Fraps Game audie recording: Fraps Microphone recording: Audacity Video editing: Sony Vegas 9
Action! for Video and Game Audio Audacity for Mic Recording Haven't really found editing software I like yet on the PC, but you don't need anything powerful for game casting. Often I'll just use Adobe Premiere Elements, or if I want to edit much faster, I'll use FCPX/Motion on the Mac. Again, I haven't really made use of these for game casting, more just hobby special effects.
