Questions
How is the needed speed calculated?
Divide the length by the time you have. A 90-minute lecture in 60 minutes needs 90 ÷ 60 = 1.5x.
What if the result is above 2x?
Many players stop at 2x. Above that, consider skipping parts or splitting the viewing.
Why is the speed rounded up?
Players use steps like 0.05 or 0.25. Rounding up makes sure you finish in time.
