"The first time it was used ... the process was recorded in 25 frames taken at an interval of 400 femtoseconds"

1 / (400 femtoseconds) = 2 500 000 000 000 hertz

So definitely in the "trillion fps" for a very short period of time with multiple frames.

What is confusing is why they call it 10THz when it appears to be (on average 400/25=) 16fS/frame or closer to 60THz.

It's almost like they are underselling it?
