I hope that you are all having a great evening. Today I was watching a recent lyric video from Ed Sheeran and I wanted to get your advice/opinions on how you would go about creating two of the effects I took a liking to. The first effect of which I am talking about is applied to the background, it almost looks as if the tie-dyed background is liquefied although I'm having a slow evening in regards to thinking. The second effect of which I took a liking to is the paint brush strokes which the lyrics lay on, the only way in which I can describe these is that they are trembling, although I am hoping you will expand on this further.
In case you aren't too sure of the video I am speaking of, here is a link so you can get a much greater understanding of what I am talking about.
