Hi, sorry for jumping in late but I can help you with this (as I'm the person who made this video

People used to enjoy putting these videos on as background noise. I honestly have no idea why people watched these videos, but enough people did that I made videos each time I flew. I guess, think someone who does a full 'flight sim' flight on their computer to feel like they've gone somewhere without going there - but with an actual video. The Qantas one was a challenge due to the length - the Gopro was either connected to a power bank or to the USB seat power (I think this one had USB so I used that) and back then, they didn't use a tonne of storage so a 128GB MicroSD was more than enough. I think total file size encoded and uploaded was around 17GB.

They became quite a technical challenge as time went on, and I stopped making these videos around 2018 and focussed on the in person 'vlog' type content (ironically right after this trip).
