Well, in fact, it's an option already - it's possible to define a key binding to disable hud.
Some other things I managed to learn:
- the only program I found that allows capturing video is fraps. All other video capturing programs i found just sucks.
- good place to get sounds from is freesound.org
- good place to get music from is jamendo.com
- the most tricky thing when recording is to keep the camera moving smoothly. I usually use EK flybys but it really requires smooth mouse moves.
- always record shots longer than you want. You will need about 1-2 seconds on each end of a scene for transitions.
- take as much shots as possible - you will have something to choose from.
- making a 5 minute video with sound, some simple added special effects, music and recorded voices, took me about 30 hours.
- making such videos is much fun and is addicting;)
