Hello! I used the effect wave warp and want to adjust the speed with keyframes, it should slowly move faster. When I set keyframes on the speed with the stop watch, they are squares and they jump abruptly, not slowly increasing. I found this Keyframe interpolation in After Effects but it didn't work. In the interpolation dialog box everything is greyed out except "hold", and in the graph editor, I only get a warning pop up "no valid interpolation method" and then AE completely crashes. I hope someone can help.
Some effects simply cannot be animated in the manner you want, especialyl ones that auto-animate like Wave Warp. It messes with their internal math. You have to think of something else like creating a static wave and animating iot with a Motion Tile effect or using Displacement Map with a custom map.
Pre-compose your Wave Warp layer moving all attributes to the new comp. Add Time remapping to the pre-comp and adjust the speed curve in the graph editor so it looks like this.
That project has wave warp animating only wave height, but then the playback speed goes from no time passes or zero seconds per second of realtime to 5 seconds per second of realtime or 5 times faster than normal.
