How to Fix a Flicker/Wave Artifact (horizontal)

[Doug Metz]

Looks like an interlacing artifact, based on the spacing of the ‘wave’ and angle of the shot.

Spot on—I’m in a 29.97 interlace timeline (though footage is progressive).

Now, if I could fix, lessen the artifact…

Thanks, Doug

Easy fix – select the project in the browser, and in the Inspector, select the Info tab. In the upper right corner, select ‘Modify Settings’. From there, you can change it from 29.97i to 29.97p

I have to export (share) in interlaced form (TV)…

Does it show on your interlaced video out or are you using a computer screen? They don’t show interlaced as, well, interlaced.

Watching on computer screen.

And it must be the interlaced timeline: I dropped the same progressive clip in a progressive timeline—no flicker/waves.

Still wonder if there’s a fix.

Thanks, Bret

Progressive 30p in an interlaced timeline should look progressive. The fields can’t magically appear out of thin air. Well, they’d be there, but they’d be made from the same progressive moment in time so there wouldn’t be any visible interlacing. However, if your footage is actually 60p, then FCPX will map that to fields, which is what you want. 60p is 60 images per sec just as 29.97i is 60 images per second. It won’t look that way on TV. TV is either 720 60p or 1080i. Both are 60 images per sec. None of it looks interlaced in TV. If you’re also distributing for computers, you need to create a de-interlaced version for that.

Thanks, Brett. You are right.

What makes this weirder (to me), is that when I share the master file (XDCAM 35 mbps), I don’t get any of the flicker/waving. It only occurs on that timeline. In fact, when I just look at the clip in the browser…no flicker/waving.

Only in timeline (with effects on or off).

And what size is your viewer? Not 100% I’m guessing.
