How to bookmark a timestamp in a YouTube video (4 ways)

You are forty minutes into a conference talk when the speaker finally explains the thing you came for. You will want it again next week. What do you actually do with that moment?

YouTube has no built-in answer. Watch Later and playlists work on whole videos, not moments inside them. So people improvise, and the improvisations have very different costs once you have more than a few. Here are the four that work, in rough order of effort.

1. Add a timestamp to the URL

Every YouTube watch URL accepts a t parameter that sets the start time. Append ?t=90 to jump to ninety seconds, or &t=90 if the URL already has a query string:

• https://www.youtube.com/watch?v=VIDEO_ID&t=90 — starts at 1:30
• https://www.youtube.com/watch?v=VIDEO_ID&t=1h2m3s — starts at 1:02:03
• https://youtu.be/VIDEO_ID?t=90 — the short form works too

You do not have to build this by hand. Right-click the player and choose Copy video URL at current time, or tick the Start at box in the Share dialog. Both produce a link pinned to the current frame.

This is the right tool for sending a moment to someone else. It is a poor tool for your own memory, because the URL records where but not why, and you still need somewhere to put it.

2. Save timestamped URLs as browser bookmarks

The obvious next step: copy the timestamped URL, press Ctrl+D (Cmd+D on a Mac), and file it in a folder. No tools, works everywhere, syncs with your browser profile.

It degrades fast, though. Every bookmark title defaults to the video title, so ten moments from one lecture produce ten identical-looking entries. You end up renaming each one by hand, and that friction is usually where the habit dies.

3. Keep timestamps in your notes app

Paste timestamped links into Notion, Obsidian, Apple Notes — whatever you already write in. You get real context around each link, and the timestamps live next to the rest of your thinking on the subject.

The cost is the context switch. You are alt-tabbing away from the video every time you want to save something, which means you either pause constantly or stop saving things. It works well for deliberate study sessions and badly for casual watching.

4. Use an extension that lives in the player

The reason the first three options leak is that saving a moment costs more attention than the moment is worth in the instant you notice it. The fix is to make saving nearly free.

That is what a timestamp extension does. A keystroke stores the current time against the video, and the timestamps render on the progress bar so you can see the shape of what you saved without leaving the page.

YTMark takes this approach: press B and the current moment is saved with a thumbnail of the frame; press Shift+B to open the panel and jump between saved moments. Everything syncs to your account, so the library follows you to another machine. It is free for your first video, and Pro lifts the limit.

Which one should you use?

• Sending one moment to someone — URL timestamp. Nothing to install.
• Two or three moments you will need this week — browser bookmarks, renamed properly.
• Studying a subject across many videos — your notes app, where the surrounding thinking lives.
• Saving moments regularly while you watch — an extension, because everything else is too much friction to sustain.

These are not exclusive. Most people who save moments seriously end up using a URL timestamp to share, and something more structured to remember. The question is only which one carries the daily load.
