Yes, CCD video cameras work at a framerate of 60 frames per second, and are shutter based so that the actual exposure time (which depends on the available light) will only expose the CCD pickup element for a fraction of that 1/60 second frame.
If you look at the video, it appears that the propeller is moving very slowly, when in fact it is moving very quickly and is just being captured in a "stroboscopic-like" effect.
In film, it's often called the "wagon wheel effect" because in the 1950s Westerns, the frame rate of the camera and the rotation of wagon wheels made it appear that the wagon spokes were rotating backwards, when in fact the were not.
Here's the full collision vide from Rumble. You will see the bent propeller only in the last few frames before the video ends, so keep watching when the color bars pop up. The image returns.

[the frame rate of the camera and the rotation of wagon wheels made it appear that the wagon spokes were rotating backwards, when in fact the were not.]
It’s an interesting effect. I was in Branson several years ago and was watching a ferris (!) wheel at night - of course it was rotating.
I could concentrate on it and at various points it would appear to rotate the opposite direction. It was at an angle which I believe (?) makes it easier for this effect to happen. Of course it didn’t rotate the opposite direction but the visual made it appear to (sometimes).
If you watch closely you can see the first SU dump fuel temporarily blinding the camera, the the second SU tries it and hits the prop which is clearly bent in the last frames.
Thanks for the collision link.
