1080 30p
Question regarding 1080 30p. We’ve recently shot some footage using the HVX 200 at 1080 30p. With DVC ProHD I know this is an anamorphic HD at 1280×1080, and this is okay because the final video for a websites landing page, but with the frame rate being 30p, is this handled the same way as with shooting in 720 30p?
I guess I’m just a little confused of my last project. Our post facility sent me the final video at 1920×1080 30p, but this was actually an Interlaced video because pulldown was added to a 23.976 sequence and FCP interpreted the ProRes (from another post, I’ve learned ProRes doesn’t always contain the correct metadata) video as progressive when it was actually interlaced.
Also, I’m just not clear on the whole PsF thing. Is this mostly used in PAL? My understanding is that video is recorded as progressive footage but in interlaced frames. So for every 2 fields of a still frame that = 1 PsF’s or one progressive frame. Where as interlaced splits motion frames into separate fields. Sound right?
So I guess my overall question is, is the 30p footage from the HVX actually 30 progressive frames running at 29.97 or is it PsF? And do I need to do anything different in FCP 7 to edit this material?

Hi Matt,
I do not belong to the NTSC world, but I don’t think that just because you add pull-down, that Progressive footage become interlaced. That’s just Progressive with added pull-down.[Matt Campbell] “Also, I’m just not clear on the whole PsF thing. Is this mostly used in PAL?”
Not only in PAL. All the HDV 1080p30 is recorded as Psf.[Matt Campbell] “Also, I’m just not clear on the whole PsF thing. Is this mostly used in PAL?

Matt, a PSF frame is just a PROGRESSIVE frame, but Instead of being read sequentiality ( line1, 2, 3, 4, 5..) lines are read in other order (line 1, 3, 5,..then line 2, 4, 6….).
The only thing you need to do is to check it as Progressive (NONE) in FC or any other application.
