FAQ
How is it calculated?
Page method: about 55 formatted lines per page, one page ≈ one minute. Reading method: dialogue words ÷ words per minute, plus 3 seconds per action line.
Is it accurate?
Both are estimates; direction, pauses and action change runtime a lot. Use the range between the two numbers.
Does it work for vertical short dramas?
Yes — with 1–3 minute episodes it helps you see which scenes run long.
