The idea is to have a character running on the spot, with the background (bushes on either side of the path and the path itself) scrolling into the distance, preferably on a loop so we can simply repeat it for the entire length of the shot (about 10 seconds). What would be the most straightforward way to accomplish this? I've had a few thoughts, but they seem a little convulted — mostly involving animating each bush and path pattern by hand which is laborious and problematic if we need to tweak the length of the shot.
I was thinking that a loopout/cycle expression would be the best way to go, but the problem is getting the backdrop to loop seamlessly in the first place!
Apologies if this is a bit of a novice question — still fairly new to After Effects and been staring at a screen all day, so am a bit frazzled and probably overlooking a really simple or obvious solution. Many thanks in advance for any suggestions! :)
A single bush applied with Effect>Stylize>Motion Tile should give you the repetitions you require. Then animate Motion Tile's Tile Center property.
Make the layer 3D and set its y-rotation to taste.
For a seamless loop, view the Tile Center's property in terms of % of source. To do this, initiate the contextual menu (right mouse button click on the said property) and choose Edit Value. A pop dialog will appear. Change units to %of source. Set this value in multiples of 50 (150,250 etc) to achieve a seamless loop.
The 'ground' layer can be created analogously.
