TimeX Function
This applies a rule to change timing on the input clip. By default, the value is time, which means that at the current frame, it uses the current frame, or no change. However, by modifying the formula, you can get interesting effects. Like Lookup and ColorX, you can duplicate most other Time functions with TimeX. These other functions are, generally, just macros with TimeX in them. The other functions were made becomes sometimes TimeX is counter-intuitive. Here are some examples mimicing the other functions.
Another more complex example would be to animate 360 3D frames with an
animated light. The light is from the right at frame 0, from the top at
frame 90, from the left at frame 180, etc. You then position a fake light
source in the composite. By figuring out the angle of the light to the
3D element (using trigonometry), you can pick one of the 360 input frames
to fake the lighting change.
