What it is
A 45-minute compilation of ground-based film and video of Space Shuttle launches from STS-114, STS-117 and STS-124, rendered in high definition. It was produced by Matt Melis at NASA's Glenn Research Center from the Shuttle imaging team's engineering footage, with narration explaining the imagery.

Considering the Space Shuttle main engines as an example and building on Organic Marble's answer, the start-up phases amount to some transient effects while mixing the fuel and oxidizer while building up thrust and developing a steady-state flow out of the nozzle. You'll often see un-burnt hydrogen and clouds of oxygen as the mixing occurs and the initial flame builds up. Although it happens very quickly, it still takes some time to develop the flow to steady-state, so you get a bunch of different phenomena happening like shock cones and plasma. This video [this video] commemorating the Space Shuttle from an engineering perspective has probably the best available footage of the SSME's starting up

Still away from home, but did you see the one called, I think, "Ascent"? It has a lot of engineering footage in it. On youtube: [this video]

The question Please explain the time reference shown in Shuttle launch engineering video [LINK] links to the very cool video Ascent - Commemorating Shuttle [this video] . After about 22:25 in the video there is footage from "Camera 33" showing the external fuel tank and one solid booster. As the booster passes by on the right side of the image, I noticed the following sequence of things pass by, superimposed on the otherwise smooth white matte surface of the booster. Question: What are these, and what exactly does "LOADED" mean?

@JCRM figured it out [LINK] . After about 04:45 in the video [this video] : The time code that you’ll see in the LED display on the right hand side is actually positioned between the two sprockets on the 16 mm frame, and the time code is UTC time code, it’s in IRIG-B format [LINK] , and you’ll see it’s 21 hours, being UTC it’s 5:02 PM local time, 2 minutes, 11 seconds, and the three digits that are moving in the upper right corner would be representing one thousandth of a second. The solid number 1, the second digit from the top, is indicating the synchronization of the camera. The narration also mentions early on that the film starts at about 6 seconds before launch, and one can see that recordi

Many shuttle launch engineering videos show an apparent time reference to the right of the frame as red numbers counting up rapidly. For example, from the amazing video " Ascent [this video] ". [LINK] Assuming this is indeed a time reference, what is it relative to? Basically I'm asking for an explanation of this stack of red numbers, what is each row, how does it relate to mission elapsed time or GMT, etc.
