As to the length of the animation. Web based movies need, IMHO, to emulate TV adverts, quick and slick, short scenes telling a story succinctly This is an animation of a heldentenor singing an aria by Mozart. It doesnt exactly lend itself to MTV styling. =) The lengths of the cuts vary anywhere from three to fifteen seconds: its all timed to the musical phrasing more than any sense of "story". Also, this isnt a web-based piece; its ultimately for video, as old fashioned as that technology may seem sometimes. =) But Im curious: why must web-based movies emulate something as visually cluttered as a quick-cut advert? If Im animating a scene that involves, say, an intense piece of dialogue that stretches for twenty seconds, why would I want to throw in a bunch of visually unnecessary cuts just to make it bright and shiny for the web? Could you imagine Pinter done with 1 cut every second or so? Yikes!!!! The lights thing is our old friend interpolation, learn to love your graph editor, the answer's in there, check the colour dials Unfortunately, been there, done that as well. I delete the white point, and another shows up somewhere else. Arrgghh. why couldn't you simply copy the last frame to the first frame For some reason, Poser balks at what would appear to be a sensible solution like that.
