This looks very interesting, but I hope whatever end result we get includes a B/W alternative viewing option to the colorization.
The colorization provides an interesting guess at how this footage might have looked (the shade of green in the British tank in the longer Youtube video, for example) but that's just a guess.
I'm not a fan of offering this stuff being presented as some sort of "scientific uncovering of history" in terms of the colorization. It's all guesswork and might be quite wrong.
The cleaning up the B/W footage is great, however, and I wish they had just stopped there.
