Quality settings don't look right in Mediainfo

Hey folks,
I own a Canon XA10. The quality settings offer these two (and others) choices...
1) 1920x1080, 60i, and
2) 1920x1080, PF30 (which I assume [gulp] means 30p (progressive)

I shot a clip of each and ran each through Mediainfo and they showed virtually identical, as I would expect, EVEN FRAME RATE. Both showed frame rate of 29.970 and both showed scan type of interlaced.

Is this some kind of anomoly or am I not understanding something?

Appreciate anyone who can shed light on this.

Thx,
Harold

PF30 is Progressive Segmented Frame. It shoots progressive and puts half of each image in each field of an interlaced file.

The difference from an interlaced image is that both fields are captured at the same moment in time and if you combine them you get a progressive frame.

It does show up as interlaced since that is how it is stored. I use Cineform's HDlink to capture and it will unwrap them into a progressive file.

I'm not sure, but if you bring them into a vegas 29.97 progressive project and set resampling to off and deinterlace to blend it "might" unwrap it properly.

Thank you bastinado. I'll see what I can do and report back.

I gave it a try.
1) How do I know if I've been successful? Do I have to render it and then check that rendered file?
2) Why do I really want to do this? This clip drops onto the timeline, edits OK, and renders OK. Is there any practical reason to try to "unwrap it properly"?
