Where can I find a slow-motion video of a focal-plane shutter in operation?

I'm preparing a beginner photo club presentation about exposure and want to show a short real-world slow-motion clip of a mechanical focal-plane shutter operating. I've already found animated explainers, but I specifically need footage of the actual shutter mechanism rather than diagrams or interactive demos. Are there any good video examples available online that clearly show the shutter curtains moving?

Would a video like this serve your needs? It is currently posted on YouTube, an I am not sure that exhibiting it from there is sufficient, or if you need it to be embedded in your own app. Anyway, useful content starts around time index 1:15.
The Shutter - Photography with Imre - Episode 2
The following video may also be useful, as it is purely a video of an actuating shutter. It is also found on YouTube:
Focal-plane shutter - Schlitzverschluss
Finally, this video may also be useful. It is not an actual video of an actuating shutter, however it has some very useful animations that demonstrate the concept. It is primarily discussing the effect of flash and flash duration on photography, and how that plays into the length of exposure and the nature of the actuation of the shutter at different speeds.

Yes — this is a useful request, and there are a few types of clips that fit.
Community recommendations point to YouTube videos showing actual focal-plane shutter operation, including one focused specifically on an actuating shutter (“Focal-plane shutter / Schlitzverschluss”) and another educational video where the relevant shutter footage begins around 1:15 (“The Shutter - Photography with Imre - Episode 2”).
Another suggested example is high-speed footage of a Nikon D3 shooting at 11 fps and 1/4000s. That kind of clip can be especially helpful because it shows how a focal-plane shutter forms a moving slit at faster shutter speeds, which also helps illustrate flash sync limits and why high-speed sync exists.
For a beginner presentation, the clearest choice is likely a short real slow-motion clip of the shutter curtains themselves, optionally followed by an animation to explain what viewers just saw.
