There is a signal difference between p and psf, your signal is psf. Either change to p (if you can) or capture 1080/60i as that is the correct way to capture psf.

Dude, that's between you and your output device. The capture device has nothing to do with. ;)

I dunno. But I'd just capture 30psf (read 60i mode) and be done with it. The image can still be progressive even if its flagged as I.

Cause you're not capturing 60i. Not really. Your signal is still 30p (assuming you set your output to that) psf means "progressive segment frames" and is just a way to transmit progressive material over an interlaced pipe.

So while the signal may seem like it's interlaced it's actually progressive, and once captured properly is indistinguishable from a signal transmitted in a progressive pipe.

Most video signals (even progressive ones) are transmitted as psf. Even in professional environments.

Also there isn't a "massive" difference in quality between 1080i and 1080p, but that's not an argument I'm inclined to get in to. ;)

Like I said, feel free to spend your time trying to get the DVI signal from your graphics card to be P instead of PsF. I don't know how to do it, or even if you can. But I do know, if what you are outputting is a PsF signal, you're not going to gain literally a single thing from all your efforts.

Hmm.. In the captured clip, or just your preview? Also, did you change the output setting on your card? What refresh rate is your monitor set to?

In the captured clip and the preview.

Yeah I changed the output settings.

Refresh rate of my monitor is 120hz and it's being cloned with the black magic card.

EDIT - Just changed the refresh rate to 30hz, but the tearing is still the same. I'm thinking my hdmi cable might be causing this?

What are you trying to capture?

A streaming video perhaps?

Hmmm. Tearing is usually because the render refresh doesn't match the display refresh. HDMI cable wouldn't cause it. I think you might need the help of someone that regularly does game captures. I just work on movies. ;)

U could try refreshing at 60hz and setting capture to 1080/60p, see if it works. Generally higher refresh rates = less tearing.
