High-Resolution Digital Video Notes
Video to film looks so bad because, in general, video has much lower
resolution than film. However, we can use a custom video format, with
extremely high resolution to get aroud this problem. To get an idea of
what can be done with that now (let alone ten years from now) go to a
theater showing of Jurassic Park and watch the T-rex sequences. The T-rex
scenes are particularly illuminating since some are done with stop-action
animation and some are done with computer graphics (which techniques we
would use for video to film). Remember that I'm not talking about home
camcorders, but high quality stuff, as good as or better than that used
by Industrial Light and Magic.
If the resolution is high enough, then we can do a lot of the "camera
work" in post processing. This would involve using a wide-angle lens on
the camera and doing panning, zooms, and the like by selecting out portions
of the frame to transfer. Zooming would be by selecting a portion of the
frame around the section you are zooming on, then a smaller portion, then a
still smaller portion, each time blowing up the image to fit the object
frame. For panning, you would start with a subset of the frame at one side,
then select a same-sized subset shifted just a bit, then another, and
another until you've swept across the area you mean to portray.
Further post-processing effects (which are easier to do with a skilled
cameraman working under a talented director so they wouldn't be used much
in most moviemaking but may serve us well) could include using controlled
distortion to simulate different perspective effects (and thus simulate
different lens focal lengths), color and brightness adjustiments, the
effects of filter and lens tricks (like multiple images, vignetting, etc.),
and other things.
