This is a little overdue, but I made this sortable-searchable browser for the @Livermore_Lab YouTube films a while back, because I found YouTube's interface impossible to use to make any sense of the ~500 nuke test films they had uploaded there. Enjoy: http://blog.nuclearsecrecy.com/misc/llnlfilms/

The yields is given too in the title. So wonder if that be used to determine distances? Or scaling? Seems like these could be used for training AI for something....
If you knew the timing (not always clear), yes, you could work backwards from the yield (assuming it is accurate — part of why they were re-processing this footage was to calibrate yields) to get the distance scales.

Currently thinking about fireball expansion rates to estimate scale..

You'd need to know how many frames per second the reference footage was shot in, which is not always clear.

Yes, that is a challenge! Many don't have frame count, and "what's a timecode?" :-)

And the expansion rate scales nonlinearly it seems.
