  Re: Using VCR's to digitize with DCTV.


  I bought last year's Hitatchi VT-M132A with 'scanalock'. It has a little
knob on the back that, when twiddled, does a pretty good job of eliminating
the jitters on freeze-frame. Also, it will 'single-step' from frame to frame.
I don't know how it does it, since I thought videotape uses a different
method of display, but ti works. DCTV digitizes them quite nicely. (It was
a great deal at $200!!)

 However, my attempts to rebuild a series of frames as an anim have failed
at DCTV color-levels! Every time I try, makeanim barfs with 'out of memory/
can't write file' in the second frame. My guess is that there are so many
color pixel changes between the frames that it can't handle it. I have seen
an anim of the space shuttle launching done from videodisc, so it can be done.

Note that I can use the convert program to scale the colors down to 32 (ehb)
and do a non-DCTV anim, but this has mucho chroma-type artifacts. A neat 
effect, but not as cool as what I am looking for....
