Sorenson is not bad. It will produce a samller, cleaner looking and
smoother running file. However, if you want to maximize your audience
to include the Linux/Unix geeks, you should compromise quality for
compatibility--Cinepac is usually the best of the alternatives. (I
hope you're running a reasonably fast machine to do the compression.)
Another key to getting good compression is to start with the best
quality tapes you can and use a quality source deck for digital
capture. The notion that the transfer to digital is "lossless" isn't
really true. Since most compression schemes work using some sort of
principle that looks for "deltas"--changes in pixels from
frame-to-frame--that big 'ol white flash-o-dropout is going to
increse your filesize significantly. The same goes for any noise in
the signal. Noise does not like to be compressed. I'm sure there's
only so much you can do with your source tapes in your home "studio"
but you might want to consider this when making edit decisions
regarding your final product. (i.e. "Gee, if I cut away from this
shot two seconds earlier, I avoid that big chunk of noise...")
As for format, I have certain bias towards Quicktime.
And for the record, I defer to Bill Adams in all things technical in
this market. I've been away from video for the past couple of
years--though it looks like I'll be back to it shortly. Bill's been
living and breathing it.
