  • Video Strobe effect FCPX with editable hold frames

    Posted by Randy Lundquist on March 5, 2013 at 8:17 pm

    Just made the switch from FCP6 to FCPX and one of my go to filters in 6 is gone, STROBE. I’ve been trying to figure out how to create one in Motion 5 but with no luck.

    I’m looking for a video strobe with editable holding frames.

    In motion 5 there is a strobe in the retiming behaviors but when I try to apply it to the effect source nothing happens. What gives?

    Do you mean like this?

    I’m not familiar with the FCP6 Strobe effect so I’m not sure if that’s what you’re after.

    There are two ways to do what you’re looking for – a simple way, and a complex way. First, Motion has a Strobe filter (Library-Filters-Time-Strobe). Create a FCPX Effect, add Strobe to the source, publish Strobe Rate and Mix, and you’re done. This unfortunately doesn’t give you precise control over the frames, but by controlling rate you can get close.

    If this doesn’t give you enough control, the best option is to bring the footage into Motion and keyframe it manually. I’m not aware of a way to publish those keyframe controls to FCPX, unfortunately.
