How to achieve this crazy bi-pack effect in FCPX?

And Sometimes the Boats are Low [1983, from Leighton Pierce Archive] on Vimeo

“And Sometimes the Boats are Low” by Leighton Pierce is a short experimental film that, according to the web, used a multiple pass bi-pack printing technique on an Oxberry animation stand to achieve this effect. 

I'm wondering how I can achieve the same effect on FCP using multiple static clips with movement as such.

Barudie, that's a cool effect. What a neat idea for showing a "time lapse". Thanks for sharing that.

One thought is that you could try contacting Leighton Pierce and ask him/her about the process he/she used.

I did something similar many years ago, but I can't recall exactly what, off-hand (I did it in FCP 6 or 7, and maybe using Motion). I do recall that I stacked several clips on top of each other, some shifted in time, then using some sort of cropped framing that moved to animate the "slices" (probably with lots of keyframing). My effect was to vertically offset vertical slices to yield a fragmented view of a character in a film (to show that his life was in a state of chaos), though I feel that the sound FX and music I used really sold the visual.

I do remember having to render the ~20 second-long clip as it was quite resource intensive, exporting it and then bringing the rendered clip back into FCP to actually use it in a sequence.

There may be a plugin/Motion Template effect that could handle the horizontal movement of the vertical "slices" in the Pierce video/film. I'll post again if I can add more (though someone else likely has a more clearcut answer)...
