Progressive Clips: How to identify them in a Bin?

[David Roth weiss]

If the clips have entries that are upper or lower they are interlaced — none = progressive.

This is a “FC Basic Forum” question.

Careful here. The field order setting in FCP is just metadata.

You can capture a progressive clip from tape and have it be marked as interlaced, but really its progressive (psf).

720p is always progressive. 23.98 material should always be progressive.

SD material can be interlaced or PsF, but it’s always transmitted as interlaced (meaning one field at a time).

1080 can be interlaced, PsF, or true p.

Where it gets confusing is that you can at anytime mark the metadata on those clips as having any field order you want.

So, if you are completely unsure of the origin of your clips (perhaps someone missed marked them or forgot to turn the upper field PsF 1080 captures to none), the only way to truly check is with your eyes and a proper video monitor/capture card.

Thanks, Jeremy.

Yes, I was having trouble with a few clips that looked progressive but still had a field dominance listed. I was hoping there was another attribute to look for in the bin or ? , instead of zooming in to look at frames and sometimes having to compare them to others. I typically work in interlaced so I’m not familiar with the look enough to trust my eye without zooming in.

Thanks, R.

Hi Rafael,

See, it’s not that easy, as the field order flag can be changed at will. Some progressive video is transferred over an interlaced stream and flagged as interlaced, but it’s really progressive.

Sorry if that sounds confusing, but it can be. You have to trust your eyes and a monitor/capture card. Metadata can be changed.

Great.

What Jeremy points is a rule of thumb in whatever application you use: Whenever you import footage, check by your self that the correct field order shows on the Browser.
