What is this footage?
I’ve seen footage of what looks like oil dripped/poured into water. This link has some stills i found off of a demo reel:

It’s most likely ink dropped into water.
Digital Juice has some stock footage that includes a little bit of this stuff (Their VideoTraxx collection #3, Disc 11). It’s really quite simple to do, though. Just lock down your camera, set an aquarium in front of it, put some white posterboard behind it and drop black ink into the water. Or black posterboard and white ink. Any two highly contrasting colors.
Bring it into your favorite effects capable NLE or compositing program, up the contrast, and voila! Instant luma matte, very popular these days.

I made some very similar to this myself without any trouble and you can do it too.
1. Get either a fish tank or Lexan-like clear case and fill it with cool, distilled water leaving a few inches of empty space at the top to compensate for the movement and overflow.
2. Mix either red, blue, green or any combination of them to create a visibly darker color in an 8 to 10 ounce cup with warm water. The mixture should be almost 10-15% dye
3. You can use either a flat (non-gloss) piece of poster board or a piece of thick cloth on the back side of the tank. Fasten it to the tank and make sure that it is secure. Let the tank completely settle so that there is NO surface activity in the water.
4. Administering the dye to the water can be done in a lot of different ways, but my favorite is the “spoon” method. Take your spoon and attach it with a C-clamp to a stand or any relatively stationary item so that the concave side of the spoon is facing upward and rests at about a 45 degree angle. If the angle is not flexible, it is better to have the tip closer than farther as this will affect how the water breeches the surface. VERY carefully hold your cup-o-dye about 2 to 5 inches from the spoon and tip it quickly momentarily so that the dye flows into the water. This is most beautiful if you do it quickly and with as much dye as you can get at one time. Your total pour should be no more than 1 second each time, but experimentation could prove me wrong. A longer pour will give it more force and make a more slender and slower spread, but it often causes the dye to collide with the floor
