Promise “a 90-minute masterclass” only if the math holds. Paste durations (3:21, 12:04, 1:02:10) and get a total plus average. Use it for course landing pages and for your own weekend edit plan.
How to use this tool
- Paste one duration per line.
- Calculate.
- Publish the total on the landing page or playlist description.
- Split playlists if the total is an unreasonable binge.
Why totals change behavior
Viewers choose playlists with honest runtimes. Inflated “complete guide” playlists that are 11 hours of leftover livestreams teach people not to click you twice.
Professional notes
- Exclude trailer clips if they are not part of the course.
- For live VODs, duration includes slates — trim expectations.
