Hello. I use AE6 windows version.
Sometimes I want to make "hold interporation animations" on some layers, and time-stretch compositions that contains layers with hold interporation animation, but if I time-stretch those compostions,it ruins the hold interporaton, and make them all linier interporation. This messes up all hold interporation animations.
My layer nest is something like this.
Parent Cmposition A
Child Composition B(this composition is time-stretched, duration is 300% )
Layer A (this has hold interporation animation )
In this case, composition B in compositon A ruins the layer A's hold interporation animation if compositon B is time-stretched.Can I keep the hold interporation? Right now I pre-render the compositon B and replace it with movie file and time -stretch the movie file. Movie file doen't break the hold interporation of course.
Please help me.
Try applying the Posterize Time effect or a posterizeTime() expression to quantize the interpolation to the nearest keyframe. You could also enable time-remapping in the pre-comp linked to a slider in the main comp and instead of animating inside the comp, animate the slider. Other than that you should consider restructuring your project. Seems somewhat inefficient to work this way. The behavior is otherwise normal - when you manipulate time, your hold keyframes may end up at fractional times and AE needs to interpolate to the next full frame, which can cause short smears and blips to appear.
Thank you very much! My problem is solved.
You always give me right answers. Thank you Mylenium.
