Going by the audio, it's sped up.
I hadn't quite grasped how big the march was, but I know that part of London well and so it gives me a good idea of size (the caption saying 'Hyde Park' first appears no-where near Hyde Park though)
Good point about the audio, I played it muted initially. But at the same time the helicopter (assuming it was G-TAKE or pretty much any
Arena Aviation helicopter) AS-350 series makes the same noise when flying at high speeds as opposed to just hovering or slow movement.
Also, one big pet peeve of mine is when aerial footage shown here in the US and I assume elsewhere they keep the NAT sound of the helicopter. To me it’s annoying - but what’s even more annoying is when you hear squelching sounds where I have heard it’s either data for the helicopter sends out to its location for the tracking receive site to point or used for the IFB.
Edit
: Here’s an
example of that squelching noise. I’ve heard many times on many stations across the country.

Don’t let anyone treat you like you’re a VO/SOT when you’re a PKG.
