Before we get into "live" vs. "not live", let us be clear: Viruses are composed of few molecules, so they are very small; viruses cannot reproduce or carry out metabolism absent a host cell; viruses take over the host cellular machinery to do everything from reading their own genetic code to reproducing their genes to building viral proteins and other molecules and assembling the progeny viruses. A virus is but packaged genes, either RNA or DNA, plus tools to invade a host cell.
No videos, but various electron microscopes can be used to take photomicrographs of viruses at very high magnifications. Use Google "image" to search the words "bacteriophage" and "virus". There are some lovely pictures of bacterial viruses [bacteriophage] on the first and second pages that pop up. There are also drawings made from electron microscope images.
You are correct, but "Cyanobacteria" is a wide and inclusive term for ancient photosynthetic bacteria. "Beggiatoa" is the name for a group of the Cyanobacteria that require hydrogen sulfide. They use the energy of sunlight to remove the hydrogen, releasing sulfur. Look up Beggiatoa in Wikipedia for more. Diatoms do look like boats - you can read about Diatoms on Wikipedia, too.
Beggiatoa are salt marsh bacteria. Other bacteria that live on decaying material in salt marsh ponds release hydrogen sulfide. Beggiatoa require this hydrogen sulfide. There are probably more than 100-million species of bacteria, of which less than 100 cause human disease. If you encounter bacteria, the odds are 1:1,000,000 that they will cause disease! As far as is known, Beggiatoa cause no human diseases.
Bacteria are not only single "cell" organisms, but their "cells" do not even contain cellular organelles such as mitochrondia or nuclei. Essentially bags of highly-organized chemicals. Bacteria show many responses to their environment. A few response mechanisms have been predictively explained as chemical. Only critters with highly-organized nervous systems are thought to exhibit any form of "consciousness". Most biologists feel that there is no explanation of "conscious" that is useful.
Your comment is appreciated, but actually, the Sony has not turned out to be as good as the Nikon Coolpix when it comes to videomicrography. Control of the aperature is limited, often resulting in a dark background and shallow focus. That said, even LWD lenses give a depth of field around 50-microns. The thin film of water between cover glass and slide is still deeper that the field depth, living critters move up and down, so staying in focus is rather difficult.
Hmmm. I notice some other critters in the film: Some out-of-focus rapidly-moving dinoflagellates; Small black rotating S-shaped Chromatium [another species that uses hydrogen sulfide] among "stuff" in the lower right quadrant toward the end of the film. The salt marsh is a very rich ecology, absolutely vital to the health of the planet.
Click-on <more> under Owner Options. Beggiatoa require both sunlight and hydrogen sulfide. In a salt marsh, the hydrogen sulfide comes from critters in the mud. Beggiatoa moves up and down in the shallow water to balance sunlight and hydrogen sulfide. In the early morning, one often sees a gray cloud of Beggiatoa near the surface, catching the rays while there is plenty of hydrogen sulfide in the water column.
The thick mottled rod moving diagonally is Beggiatoa. The skinny mottled rod is either another species of Beggiatoa, or a related genus. The critter with a green bow tie is a diatom. The fine filaments are an unknown bacteria. All live in a salt marsh.
I wish they could make videos like this with even smaller organisms... Like viruses (though many don't think they're alive).

the worm looking thing r cyanobacteria right?? and the boat looking one is a diatom??

Are these things conscious like us?

Open up the aperture dude! Then eveyone won't bug you about the out of focus stuff...

See my comments in response to dlindeman. The microscope magnification was 400x and the videomicrograph was at 3x optical zoom.

What type of creatures are the other stuff? Protozoa?What size are these things roughly?
