I guess this reveals how fucking dumb I am. I can’t get the math to make sense in my head. If you watch at 1.25 speed, logically (or illogically I guess) I assume that this makes the video 1/4 shorter, but that isn’t correct.
In short, could someone reexplain how fractions and decimals work? Lol
Edit: thank you all, I understand now. You helped me reorient my thinking.

speed=distance/time
Take a 100 minute video, the distance is the number of minutes the video is long. So if watching normally at speed=1 then, since distance=100, 1=100/time. From this we get that time=100, in other words it takes us 100 minutes to watch a 100 minute video at normal speed (duh).
Now say we bump speed to 1.25. We now have 1.25=100/time. So time=100/1.25=80, a reduction in 20%.
The reason a 25% increase in speed leads to a 20% decrease in time is because 1/1.25=0.8.
