Starting at the beginning of a shot where I panned the camera, I noted where I saw interlacing ("yes"), and where I did not see interlacing ("no").  I'm not sure how to decipher this:

> Regarding Dave Keleshian's question, "if one is interested in de-interlacing, why introduce a pulldown in the first place?"  Actually, I only started thinking about de-interlacing after the transfers were done, after capturing all of them, and then experimenting with compressing to H.264 without de-interlacing.  The resulting H.264 file plays with "combing" artifacts.
