  • Time remapping problems, issues, 7.0, overshoot and snap back in time at keyframe

    Posted by Greg Neumayer on August 5, 2006 at 5:30 pm

    I’m trying to time remap some cloud footage to move very quickly then quickly ease down to normal speed. So, I’ve turned on time remapping, which has given me a start and an end keyframe. I make a new keyframe 75% of the way down the timeline, then slide both that keyframe and the last one back toward the start, so that I get about 800% speed then still get 1:1 framerate (100%) after my keyframe. Then, I “easeIn” the middle keyframe, so that the speed quickly ramps down to normal speed, instead of a hard speed change.

    Here’s the problem: With either the time-remapper quality or the layer quality set to draft, everything moves correctly, but if I switch both of them to high quality, the frames aren’t the same, and I get an overshoot and snap back in time when I hit that transition keyframe. No amount of tweaking to the ease handles seems to help, (unless I simply have a linear keyframe with no easing). What’s going on? I love that AE incorporated their own inter-frame morphing (apparently), but it seems unusable at this point. Anyone else have the same issue? Any workaround (in AE)?
    Is this a known bug?
    Thanks,
    Greg

    I should clarify, where I said “time-remapping quality” I should’ve said “frame blending quality”.

    Thanks Dave,
    After trying your suggestion, I realized that even with one linear keyframe, I was still getting a mis-match and reversal of speed just before the keyframe so I started thinking… and sure enough, my 29.97 footage was actually shot at 24, but I hadn’t yet plugged in a 3:2 pulldown, which was messing it up.
    Thanks!
