The documents of a particular cryo organization are separate from, for example, the personal drawer a a Cryonics Institute member can arrange for. A few cryo organizations have passed by the elwayside while their patients have been passed to other groups to keep cold; it’s not impossible that a cryo org’s records of the methods of preservation may be lost or corrupted while an individual’s personal copies remain intact. Adding a video record on top of the standard records seems to be unlikely to help directly, but it may help remind the people involved to make extra copies and backups of the relevant info.

Then again, I could be wrong.
