Yup, the whole video is screwed in about six different ways.
90% of the video is old B-roll footage pulled from other videos. She tried to adjust the speed of existing clips to stretch for time or to spice it up a bit and try to dazzle us with style and some frame-rate speed-ramping:
But you can't just adjust the speed of existing time-lapse footage or fixed frame rate footage like that without it looking completely fucked. It needs to be shot at a high frame rate otherwise there's nothing to fill in the blanks when you slow it down and it looks stuttery, glitchy and awful.
For the desk sit-down footage, it looks like she also dumped in footage that didn't match the overall frame rate of the exported video, so there's skipped frames and it all looks juddery.
I get the sneaking suspicion that Martha edited this. It's just as incompetent as Ruby's usual abysmal editing but in a distinctly different way. Whoever did it, there's no excuse for Ruby never giving any slapdash shitshow of a video a second glance and just uploading it without hesitation.
