I spent over 3 months synchronizing a line rider track to Beethoven's 5th drawing everything by hand. There is no animation happening here. Any time a character leaves the screen they are being directed by unseen lines to the next location. This is not the full length of the piece. I spliced together parts to make it possible for me to finish the project in a practical amount of time. I don't think my sanity could handle 3 more months of this song. YouTube post processing seems to create a few millisecond audio delay if you are watching on the mobile YouTube app. If you notice this, watching the video in any web browser won't have this problem.
