Not stupid. Maybe plausible in some cases to do alpha channels in flash BUT since we’ll normally need the foreground video as well in the file, not probably a good idea.

If all we were doing was switching the live feed on and off (so punter was always in foreground) then yes, this would make sense.

Maybe another idea to consider is to base the mask on the luma of the source image rather than an alpha channel. That's how I do much of my VJing.

In future put this kind of shit in blog comment so we don’t lose track of discussion for new-comers…

Looking nice.

My main gripes are with the overlaying of the live performer into an existing plate - sometimes what is directly behind them can be very distracting. Note in particular the close up on Hugo Weaving with the model overlaid - it looks as though Hugo is burying his mouth in the model's hair and singing into his scalp...

This is less of a problem for the wides and mediums, where depth perception can be a little looser, but on those close-ups, any chance to maybe matte out Hugo's face?

Other comment is placing - the current setup allows for only 3 placings, all dead centre. How about if the faders on the operator keyboard were setup for some control of lens length and lateral placement of the overlaid model?

Otherwise all sweet and good - Damon, that rotosoping must have taken you an aeon!
