Remarks: 1. With checkboxes in macro, we are choosing which parameters we will have in this effect on the edit page. You can choose whatever you need to have access to. 2. In some situations, the effect can cause an error during rendering. E.g. on the very beginning of the clip, the effect tries to take the frame which is before the first frame of the clip. It is easy to solve: take an unedited clip, apply the effect to it, create a compound clip, and then trim the clip. If you need those first frames from the start, in the Perturb modifier, change the Value parameter to be the same as Strength (or the same as Strength + 1). If you need frames from the end, make the same, but with a minus sign.
