Since a video can always be faked anyway, you can use a simpler method that is more to the point. You place a large clock in the background. You shoot the first minute at normal speed, and then shoot about 10 hours as a time-lapse movie.
I assume most cameras or editing software allow time-lapse video. If they do not, you can show the motor running for a minute, turn off the camera, wait an hour, then turn it on for another minute. You repeat that ~10 hours. This is not as elegant but it proves the point.
If the disk is spinning in open air without input power, air resistance will stop it after a few hours, no matter how good the bearings are.
