Re: [Avid-L2] Apple HDV Codec Field Order?

Hi Roger, I can confirm that Apple HDV is a mac only codec. It looks that
the problem is on the imported QT on mac, If that´s, I don´t know any way
to fix the scrambled fields inside avid. The color shift you might have if
you recapture using original tapes via HD-SDI depends on the setting that
where used on Mac Avid Import. Depending on the length of your sequence that
would be the best to do, but batch capturing HDV is not an easy task.
Hope this help.
