What it is
The first of eight parts of Richard Feynman's lecture series on quantum electrodynamics, uploaded by the channel Muon Ray. Feynman explains in a popular style how photons and electrons interact and how his path-based view of the theory works.

They are probably not on Youtube, but many of BBC's series are pretty good documentaries, although, obviously, quite "popularized". For example, their 2007 series "Visions of the future" was a 3-part series about "The Intelligence Revolution", "The Biotech revolution" and "The Quantum revolution". Their Horizon-series also encompasses many popular physics-subjects, perhaps these are what you've seen about string-theory. I don't remember the name, but one historically interesting documentary was one about how temperature and heat was discovered and how the quest for cooling to yet colder temperatures proceeded. On Youtube, the Feynman lectures stand out. Just search for "Feynman lectures" on

Particles usually know things which you do not expect! Although, this is not the answer of your question, but this brilliant series from Feynman might shed some light on it: QED [this video]

The strong interaction [LINK] explains the characteristics and operation of the strong force, one of the four fundamental forces of nature (strong force, weak force, electromagnetism, gravity). The strong force binds together quarks that compose protons, neutrons, and mesons. Gluons are carriers of the strong force. The nuclear force [LINK] is a residual manifestation of the strong force. The nuclear force binds together protons and neutrons in the nucleus of the atom. Mesons are carriers of the nuclear force. Mesons, however, are composed of quarks and gluons, so the nuclear force is an effect of the strong force. Sometimes the nuclear force is called a residual strong force. It explains th
