I watched the video without reading anything you said first... A lot of different thing definitely seemed weird as I watched it... The lady in pink pants walking away from the camera felt like she was never getting any farther away from me and walking in place or something... What was even weirder was the result of that same lady's pose in the thumbnail scrubber:
https://youtu.be/Vfw6A5uf9Tkher pose is the exact same in every thumbnail! just moved around in the frame...
And I thought to myself "Is this what he meant by faked?"... and you did.
Having said all that, it's definitely just optical illusions caused by some crazy long zoom they have on the camera... like a CRAZY long zoom. That's why it seems like they're walking forever but not getting any closer... and the lady's pose in the thumbnails is probably just a coincidence and she's walking at a VERY steady tempo.
