FAQ & Guide
Everything you need to know to get accurate playlist durations, quickly.
Quick Start
- Copy a YouTube playlist URL or ID. You can also paste individual video links.
- Paste it on the homepage and click Analyze. We fetch public metadata via the YouTube API.
- Optionally set a start/end video range and playback speed (1.25x, 1.5x, 2x).
- View totals, formatted time, and per-speed estimates. Copy or export results.
Supported Links
We support:
- Playlist URLs like https://www.youtube.com/playlist?list=...
- Shorts/Video URLs; we add them to a temporary list to total time
- Raw playlist IDs (PL...)
Speed Calculations
We compute adjusted watch time using exact duration values. For a base duration T, the time at speed s is T / s. We show common presets and keep precision to seconds.
Ranges & Large Playlists
Use the start/end controls to total only a slice of a long playlist. For very large lists, we fetch in batches and cache results to keep the tool responsive.
Common Errors
- Private/unlisted videos may not return duration data via the API.
- Country-restricted videos can cause gaps. We skip missing items gracefully.
- Invalid URLs/IDs will show a validation error. Double-check the link.
Tips
- Use ranges to plan week-by-week viewing schedules.
- Try 1.25x or 1.5x for realistic learning pace estimates.
- Export results and share them with collaborators or students.
