  • PAL roll bar on an NTSC monitor

    Posted by C. Kauffman on February 5, 2010 at 7:53 pm

    Hey all shot a project for Europe at 25P 1080 using the JVC GY HM100 (as a B camera to my EX) trained on an LCD monitor. No flicker or roll bar issues with the EX of course but the JVC footage has a nice slow roll bar going through the monitor footage that we didn’t see at all in camera. I’ve heard there are ways to even this out in AE, any way to do it in FCP?
    Thanks

    In my experience, once this is recorded…it’s there. it is on the tape. How does AE get rid of this?

    Being the interference a constant pattern, it could be fixed in AE with an “expression”.
    Needed somebody who knows well AE and patience.

    Hi Dave, actually the LCD screen pulses, slowly dimming up and down. There’s no roll bar at all. The only thing that crosses the frame is the slate at the head of the scene, but the image on the screen does change. I tried using Color Stabalizer which I read about in another forum, using a dark speaker to the left of the screen as my black and then the lightest part of the screen that doesn’t change as my white.
    Results weren’t great, all sorts of weird color spikes and QT I output won’t playback very well.
    Any ideas?
    Thanks

    Hi Dave, yeah I’ve been working on it in AE with ok results using Color Stabilizer. If you have any tips or tricks for that let me know.
    As far as a lesson, the only one I can deduce is that the screen (and eyepiece) on the JVC GY 100 blows- it’s the client’s camera not mine, thus using it as B camera. I’ve done these PAL shoots for a while now without any problems as I religiously check for this sort of thing and saw nothing of the sort until I loaded the footage.

    I wound up just masking the monitor screen and applying Auto Levels which worked pretty damn well, smoothed out the pulsating nicely. Problem now is the Quicktime I output from AE, which is the same codec etc as the original footage, crashes FCP when I put it in the sequence and barely plays in QTPro…..
