When played as raw files they have lots of blocky artifacts (which are NOT present when the orginal tapes are played on tv (ntsc)).


Hmmm, that would seem to point at a less than perfect analog->digital
(DV) conversion.



Yes. I'm going to try another dv camcorder to see if that makes a difference. It may also be that I haven't played the copy on a tv, just on my computer monitor. Maybe the tv will smear things out?





        The first thing in the "chain" was a color-corrector/image-stabilizer.
        Something like the SCC-2 from http://www.simacorp.com/ (at the time
        I used the older/first SCC-1 or SCC-Pro model).

You mean before any software? I'd always thought that software like mjpegtools was just as "good" but not as fast as hardware. IOW, should I get the ssc-2 even if I'm going to use mjpegtools as you discuss below?

        After that it was into a Canopus ADVC-100 (today that would be a
        ADVC-300 which has hardware denoising capability as well as a TBC
        (TimeBaseCorrector - stabilizer).

Same question. Now I'm just using the i1394 connection.

        Umm, probably should mention that a pipeline like that runs much better
        on a dual cpu system than a single :)

Yes. Bigger is better. I'm actually angling for an AMD64 machine next. What's 
your read between dual and 64?

I can see noise around the edges on the video. I assume I want to convert all that noise to black.What's the mjpegtools equivalent of -J mask in transcode. I masked 8 pixel on a side, which seems to get rid of that noise, and I assume will be in the overscan region anyhow.

You are the man. This is incredibly helpful. I'd never have figured this all out myself. Now I'll spend all next week seeing how it works!
