FCP won’t allow 1080psf sequence setting

[Rafael Amador]

[Richard Wirth] “I’m trying to get a 23.98psf 1080 Prores file out of FCP to HDCam.

When I try to match the sequence settings, I don’t get a 1080psf option, only 1080i even though it is a 23.98 timebase.”
Psf is but Progressive read/recorded in an interlaced fashion.
Is not a format.
Check your footage as Progressive in the browser and edit in a progressive sequence.

Rafael,

Thanks for the prompt reply.

1920x1080p is also not listed as a menu choice (see the attached file in the original post).

I mentioned psf since that matches settings found in Kona3.

Hi Richard,
1080 stuff is ALWAYS streamed as Interlaced.
– If you shoot 1080i60, that is what you stream and what you capture.
– If you shoot 1080p30, you stream it as PSF (1080i60) and you capture 1080i60.
THEN you check the 1080i60 stuff as 1080p30 and edit as 1080p30.

I’m not streaming.

I’m trying to output to HDCam at 23.98sf 1080p.

You are passing a signal through a cable for monitoring and for printing to tape.
In both cases the picture is managed as Interlaced.
Your 1080 progressive frame is read as “Upper First” and send trough the cable.
When a VTR pick that signal, it write it on tape as any other Interlaced signal.
Why to do that?
Because this way we can use hardware designed for Interlaced to manage Progressive without more spending.
To stream or print to tape that as full-progressive, we would need to design new hardware: Switchers, monitors, VTRs..
Then we would need a system for 1080i, and a different one for 1080p.
Then the ‘psf” idea is brilliant.

But again, the “psf” state doesn’t happens in your computer.
You manage that as progressive, and will be your I/O card who will take care of putting this out as interlaced (to feed monitors, VTR or whatever).

In fact 1080p is not an standard. This is why you won’t find a 1080p Easy Setup.
The standard is 1080i, which may have, as in this case, progressive content.
