Great stuff. I've always been interested in these tests.
So have I, Crossroads Baker generated one of the iconic images of the 20th Century. I did a bit more poking around on YouTube and found a channel where they take the publicly released film and try to 'clean it up' (Correct aspect ratios, clean up the sound.) and they have clearer versions of the Able & Baker official report films.

Peter Kuran (Maker of Trinity and Beyond) also released the 'Baker' segment from the film as a sample for his updated edition of the film, this follows immediately on from the 'Able' clip I posted earlier. The end of it has shots of the USS Saratoga (CV-3) sinking. I will warn that scenes from 04:14 - 04:30 may prove distressing, for as the documentary states at the end of the original film "Some animals were nuked in the making of the original footage".

I have also found a channel by someone who has dived the Bikini wrecks as well as ships from the Battle of Jutland.
