I believe the fundamental answer is breadth. Breadth in formats, in storage methods, the more the merrier. Analog, digital, physical, the more different ways we have something archived, the more likely it is that the future will be able to access it. Archive video in every major video codec and at least one analog tape format as well. Don’t let perfection be the enemy of preservation, let it be but one tool. Especially with video, it’d be better to have the only usable copy of a work in 500 years be an analog tape, than only having digital formats available that may or may not be decodeable. There is no perfect answer, because it may very well be possible that there are also no working VTRs at that time, but with multiple formats you have multiple ways to access the content
