The Lumiere Manifesto for online video. In summary:
* 60 seconds max.
* Fixed camera
* No audio
* No zoom
* No edit
* No effects
Other than the “no audio” limitation (cut voice overs yes, but natural background sound?) I think this is all eminently sensible. via Wellis
[Later: Okay, having seen a few I get the silent thing now. Will have to have a go at this I think.]
