It’s also hard to use a trig expression because the center of the comp is not “0,0” it’s 540×960 or whatever…there is a plugin on DUIK that creates null objects and zeroes out an object’s position.
You could write an expression for each object and base it off a single slider control. So if you set the slider to 10, one object would be Y+10, the next would be 90% of 10, or Y+ 9, and so on. It would be a pain to set up, but once you do you could just adjust the slider.

It’s strange, because that works sometimes, but most of the time once it starts selecting segments instead it will only do that no matter what. I can select the segments without clicking them directly either, it automatically selects the closest segments once I start dragging, and then moves them around.

Right click on the “Position” variable and click “Separate Dimensions.”
You can animate the Y separately from the X, so if you have 50 images you can set a keyframe at the base line, then set another keyframe in the future at whatever height you want them to go to, and can stagger the timing by moving the keyframes.
If you don’t want the time to move, you could stagger the layers by:
- Trim the layers to just the keyframed height change
- Selecting all the layers
- right-click and choose keyframe assistant>Sequence layers
- extend all the layers so that they keyframes remain where they are but the images remain on screen before/after the keyframes as desired.
- then the images will do a wave.
There are some free plugins that can help do this easier. Try MisterHorse.TV.
Or, you can write an expression and copy-paste it into each image. The expression would go in the Y variable. Try:
wiggle (5,1);This will go between negative 5 and 5, at a rate of 1 per second. You can mess with the numbers and come up with a pattern you like.
You mentioned some trigonometry or SIN equations but I have never done that, so I can’t help there!
