You shouldn't do so sudden mouse movements, it ruins it
If you're talking about the first clip I did (where occasionally the camera seizes and spins very fast), yeah I've learned not to do that. It took maybe 2 minutes per tunnel I went through in that so I tried to entertain myself. Had no idea it would turn out so jarring.
You're essentially watching compressed time. These take 10x as long to play through as they do to watch, meaning a 6 minute clip takes around an hour. Even super smooth mouse movements look like spasms when they're played back ten times faster. That and occasionally I'll toss something in the air or mess with scenery or something to keep myself occupied during the long stretch of time these take. I can try to keep calm in a future one if you'd like, though.
