Why it worked
The video likely performed well due to its niche appeal to machinists and metalworkers, combined with a clever visual gag that is satisfying to watch. The use of relevant hashtags also aids discoverability within that community.
Summary
The video shows a close-up of a milling machine cutting metal. The on-screen text humorously notes that the camera's frame rate appears to match the spindle's RPM, creating a visually interesting effect where the cutting tool seems to be moving in slow motion or is frozen in place. A GoPro camera is visible, recording the process.
