Hello Prof. Maliek!
Just watched one of your YT vids. It gives me an idea or two I might try out in the future, but the clip I produce first needs to be appropriate for the effect to have any meaning within it. Effects(any effects) shouldn't be added to a video just for the sake of adding effects. You need a reason to apply the effect you're going to use. For example, I make use of the "Video In Reverse" effect quite often in some of my videos(not all). A typical use might be a clip of one of my young nephews or nieces jumping or diving into a pool. I pick a point in the video just before the jump or dive, preferably at a point of an exact number of seconds(like, say, 1 minute 25 seconds, splitting at that point, then counting off 25 frames[at 25FPS] to the next full second, 1 minute, 26 seconds splitting at that point, then copy that one second into clipboard and paste it in(3, 5 or 7 times, never more than 7 though, let's not bore the viewer!) The reason for the odd number of times pasting in is that the forward motion at the start and end must mesh in with the action before and after the effect is applied. So, the resultant effect is, the child dives/jumps in-out-in-out-in... you can imagine how it looks on a screen. The reverse effect works well to bring a laugh to the viewer but is not always appropriate in every situation. I mean it lends itself well to some situations but not all.
Cheers for now!
Neil.
