I've synchronized Tchaikovsky's 1812 Overture to the full length of a Roller Coaster. The coaster twists and turns with the music, as well as triggering special effects that match the beat. The sound of the cannons are coming from the music, not the roller coaster (Tchaikovsky was a madlad). This was a challenging project because the rides in Planet Coaster do not always run at the same speed. I found that the timing changed based on changes to my CPU load or graphics settings. In total, I spent over 90 hours making this video.
The quality of this video was upscaled from HD to 4k because YouTube grants higher bitrates at this quality. I also think it solves some audio shifting issues.
