  • Suggestions for Quick(ish) Rotoscoping

    Posted by Tangier Clarke on March 7, 2019 at 4:25 pm

    I am trying to mask someone from the foreground sitting in front of an iMac (iMac takes up most of the frame while subject is frame right partially covering screen) so I can put something on the iMac screen. Is the Track Points behavior the most capable way of tracking a shape mask? It does’t seem like tracking points is the same as tracking a shape over time. I’ve been looking into using DaVinci’s Fusion for this as well as CoreMelt Slice X, but am trying to see if there’s a way in Motion to do this effectively.

    You’ll likely have to keyframe the mask points and/or mask position. You can technically track the mask but likely easier to just keyframe.

    Thanks Mark. I converted everything to 3D and although it worked in Motion, the published Z parameter had no effect in FCP X.

    Sorry to hear that. I did not test it first. In theory should work….not sure what else to suggest.

    Could it be you’re mixing threads here? ????

    Assuming we’re talking about the issue from the other thread, the 3D + Z coordinates should definitely work, yes. Just tried it. Works as expected. You must be missing something.
