Tears in Canvas Viewer in FCP 7.

[Rafael Amador]

For me looks like your video card is a bit over-loaded and not able to display properly.
Annoying but no harmful for your picture.

[Adam White] “It occurs most frequently when viewing video with fast motion and/or camera pans or movement. My first thought was that it’s a problem with the refresh rate, but this happens on both the iMac monitor and additional monitor, so I’m not really sure of how to resolve this. “

Ah, well that’s not “tearing” so much as a horizontal displacement. What I do not see in the rest of the thread is if you have confirmed this is in the media or in the display of the media. If it’s the files, the artifact will appear in exactly the same place every time you play it back. if it’s a drive or display or card issue, the artifact will move in time and in position.

I’ve seen this when capturing analog tape that has tracking or severe timebase errors that I easily fixed with a timebase corrector. I have never seen this with digital media.

Hi Adam

Did you a find a solution for this problem?

I’m experiencing the same issue in FCP 7.0.3 and Mountain Lion

[Glen Elliott]

Hello everyone- yet another plagued with this issue. The only thing that changed was I upgraded all the computers in the studio to Mountain Lion. So I’m convinced it has something to do with that.

If there is a fix I would love to know it! TIA

Here’s the solution for 10.8 users. The issue seems to be something to do with the way the new OS handles beamsync AKA V-Sync. You can force the OS to use beamsync on demand with this litte app called quartzsimple:

Open it up and press CMD-B, then select force beamsync. Now hide the app or minimize it and try playing back your video in FCP7 again. It solved the tearing for me.

Thank you John, for the link to this app. I have a 2008 mac pro with mavericks on it, and I noticed really bad tearing while previewing video with in FCP 7. After searching I finally found this thread. I used the quartzsimple app with the beamsync feature. And it works very well, there is slight tear on occasion, but it 90% better, and actually usable now. I can confirm that this works well on OS Mavericks.
