“Intellegent” 6.02 deinterlacing playback issue / bug?
I have an NTSC 30i clip of video containing 3:2 pulldown (a 29.97 ref for a film audio mixer). It has a 30i timecode window burn. I printed to video (SDI) in 6.0.2. The resulting recording was deinterlaced, 30p. Huh?
Instead of mixed field film frames, I got duplicate film frames played out and recorded — instead of AA AB BB CC CD DD, I got AA AA BB CC CC DD.
I thought Blackmagic was doing something weird, so I took the clip to another Mac with 6.0.2 and printed to video via firewire to a DV deck. Again, the resulting recording was deinterlaced, 30p. (Yup, the source clip is fine, 30i — I can see the fields here, fully 30i count with 3:2 pulldown imagery.)
I thought there was something hiding in the headers of the clip, forcing Final Cut to do this unhelpful thing? Maybe a flag carried over, since the clip was derived from another true 24p clip? So I converted the 30i clip into a .dv stream. In the past for me this has quelled any stubborn Quicktime metadata frame rate issues. DV streams have no headers. But no luck, same weirdness!
Then I tried printing to tape in 5.1.4. This worked.
The resulting recording (in 5.1.4) was identical to the original 30i clip, as it should be. How weird is that? Two separate FCP 6.0.2 machines, 30P / 4:2:4:2 (from 30i!) Am I missing something here? Thoughts? Sagely wisdom? Thank you!!

Well, now that it is not 4am I’m thinking a little clearer. Looking at the tape output today, it is clearly a problem of simply single field play to tape in 6.0.2. No matter what I do, it plays to tape as one field per frame. 30i DV file, two Macs.
So…
Help!!! 🙁
Thank you!! 🙂
