How long is this playlist?
Paste the durations. The answer — and the timeline — shrink as you speed it up.
Version 1 does not fetch a playlist automatically — that needs a server-side YouTube API key, a separate decision. Paste the durations below for now.
Total time
3 videos • Average: 29:17 • At 1.5x: 58:33 • Finish in 1 day at 60 min/day
Private and deleted videos are not counted here — only the durations you paste. Planning estimate, not a YouTube feature.
Worked example
Three videos — 10:00, 12:30 and 1:05:20:
| Step | Calculation | Result |
|---|---|---|
| Total seconds | 600 + 750 + 3,920 | 5,270 seconds |
| Total time | 5,270 ÷ 3,600 | 1:27:50 |
| At 1.5x speed | 5,270 ÷ 1.5 | 58:33 |
| Days at 60 min/day | 58.6 ÷ 60, rounded up | 1 day |
How it works
1. Each line is read as minutes:seconds, or hours:minutes:seconds.
2. The durations are added up for the total, then divided by the number of videos for the average.
3. Speed time = total ÷ speed. Days = speed time ÷ minutes per day, rounded up — so a part-day still counts as a day.
Common questions
Why can't I just paste a playlist link and get the answer?
Fetching a playlist needs YouTube's Data API, which runs on a server with an API key and a daily quota — it cannot run purely in your browser like the other WhiteUI tools. This first version keeps everything in-browser with pasted durations; an API version is only worth adding if this tool actually gets traffic.
What about private or deleted videos?
They have no public duration, so they are excluded — the same rule YouTube's own API applies. Only paste durations you can see.
