    Hi all,

    Having an issue with the vignette mask filter. And it may be, unfortunately, the nature of what a vignette does that is the problem, but I’m not sure.

    I took the vignette mask filter into motion to add the ability to rotate the shot. Reason being, we’re doing a thing where faces appear at smaller size over shots. Kind of fade up and out and I wanted to have a very faded look around the edges (and really couldn’t get any other filters to work.

    This solution seems to be working fine for any shot where the subject is fairly well centered in frame, if they are off to either side, when I add the effect and rotate it to a vertical, for reason the shot is cut off, almost to a 4×3. I’ve attached a photo that I hope shows what I mean. The shot with the girl is close to what I’m after, the shot with the man is showing the cut off on the left. I’ve turned off all other effects, tried to undo any crop or trim (that FCPX doesn’t recognize as having occurred) and no luck.

    I’m wondering if the very nature of a vignette look is that it cuts off, but I don’t have the issue on top/bottom or sides when I add the effect; only when I rotate it.

    Any thoughts/ideas on what I might be missing are much appreciated.

    You either have to make the photo “bigger” by photoshopping more background in to it (a set extension to some degree), or adjust the vignette to fit within the frame boundaries of the image.

    Thanks, Jeremy. They’re actually not stills. Talking head interviews. Curious about the frame boundaries thing…..

    The edge of the frame only goes so far. Make the vignette smaller than the edge of the frame.

    Ah, gotcha. Yes, that is sort of the issue. If you look at the second shot with the older man, you can see the full shot in the timeline. He actually has plenty of room in the frame. But when adding the vignette effect, it is choosing to cut off the frame at his shoulder/right ear (as shown in viewer). Can’t tell if it is a bug, or what. Thanks for the help.

    I see what you mean. What happens if you use the regular vignette filter and not the copy? I understand that you might not get the rotation that you need, but setting that aside for a second, does it work?

    My guess is that your motion template must not be setup correctly, and it is cropping image when not intended.

    Yeah, that must be it. Have used the regular as a work around (it works fine in terms of cropping), but as you say, doesn’t give me the vertical look I need. I’ll see what I can find in the Motion template (it was preinstalled on FCPX).

    Maybe try using “Shape Mask” filter instead? That would allow you to make a vertical oval with falloff.

    I may give it another try. I’ve never been able to get the dramatic, severe falloff I’m looking for, but maybe just need to mess around with it some more. Really appreciate all the help.

    You can move the feather and falloff controls beyond the “100” slider limit in the inspector. Just scrub the number and it will keep going making it as soft as you want.
