Mask Getting Called Multiple Times

[SenorPez]

I have a semi-transparent object, that's created by a pair of UpdatedVideoClip classes:

`        standing = UpdatedVideoClip(
            GTStandings(
                self,
                process_data=process_data))
        standing = standing.set_position(
            (0, 0)).set_duration(video.duration)

        standing_mask = UpdatedVideoClip(
            GTStandings(
                self,
                process_data=process_data,
                mask=True)).to_mask()

        standing = standing.set_mask(standing_mask)`

When I run my scripts, it seems that the standings_mask is getting updated by to_frame more often than the standings. This causes the opacity to be out of sync as the items are animated.

Any ideas what may be causing this? Or a better way to engineer this?

Think I mostly figured it out... it was getting called by the constrctor, then again by the to_mask() function. Still has a bit of judder, but nowhere near the catastrophe as it was before; I think it might just be rounding errors showing up in graphical form.
