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.
Thanks again to Conundrumer for technical support for supporting multiple riders. Here is his channel and link to closed beta:
