Re: Minimise re-encoding

Try keeping them in .mov format if that is an option. Not sure what the other options are that you refer to, but if they relate to encoding quality, it might be an idea to use a high bitrate in order to try to maintain picture quality.

I'm not sure what the best course of action is with the audio, and I'm still experimenting with stuff from my FZ8. The audio on it's .mov files is only mono, with an 8kHz sampling rate. I've tried encoding it to mpeg-2 from my test project using a sampling rate that's a direct multiple of 8kHz, eg 24kHz or 32kHz, even 48kHz - but I've not noticed any real difference in output. The audio is pretty thin in the first place, and is probably the weakest aspect of a lot of digicam video. Some Canon cameras actually have stereo audio. If you were to make up a project with a music track, you'd want to set the project audio properties to make the music sound good, using a reasonably high audio bitrate and sampling frequency. Perhaps Quicktime Pro gives you audio output options, so it would be worth experimenting with those.
