📋 Describe the SmartBlock

I created a SmartBlock to access the current timestamp while watching a YouTube video so that you can quickly add notes by doing ;;YouTube which inserts the timestamp automatically and then you can write some notes about it. Make sure to install CCC's YouTube Player script first (see Prerequisites below).

✅ Describe any prerequisites or dependencies that are required for this SmartBlock

You need to first install CCC's awesome YouTube player script. See links to Tweet and Gist below.

📷 Screenshot of your #42SmartBlock workflow/template from Roam

💡 Additional Info

Notice on this line: var currentTime = ytPlayer.getCurrentTime() - 5; I add -5 as that way as I am watching video and like a part it will actually set the timestamp to 5 seconds earlier which gives me a couple seconds to activate the smart block and then make sure I don't have the time stamp start too late. Gives a little leeway into the part I want to mark.

If you are having any issues with this SmartBlock, make sure that you paste the JavaScript block as plain text using (on Windows) Ctrl + Shift + V so that the "soft line breaks" are preserved and the entire JavaScript is pasted into a single block in Roam. This means you must copy/paste the JavaScript block separate from the title/parent block. See the GIF below.

Added a button to add the timestamps each time. Also added another small SB that converts a youtube link into the roam format youtube embed and auto indents underneath it the youtube timestamp button.

<@U013S9LL1FA> yep this is due to the "recurssive" nature / ability of smartblocks being able to call each other and itself via buttons. Remember the downsides I mentioned to you about making everything into one single SB as opposed to breaking them up into chunks :wink: hehe

[GitMurf]

But actually <@U013S9LL1FA> this gives me an idea... you can access the name/title of the smartblock I believe, right <@U016YEJAKT4>? So when I build out the buttons, I would use the actual name of the smartblock so that it would be "dynamic" I believe so that you can change it to whatever you want. If this works it probably would be a best practice. Because I totally understand why folks would want to change the names of their SB to their liking instead of just being stuck with whatever the creator uses :slightly_smiling_face: _{View in Slack}

How can I change the 『Add Stamp』button background color?I use the dark mode in roam,therefore the background color let this 『Add Stamp』not obviously~~~

[abhayprasanna]

Here is a simple SmartBlock add-on for this that will set up the following template for you if you have a YouTube URL copied into your clipboard.

• #42SmartBlock yt - YouTube

  • {{[[youtube]]: <%CLIPBOARDPASTETEXT%>}}

  • transcript notes:: {{Add Timestamp:42SmartBlock:YouTube Timestamp:varYTbut=y}}

    • <%CURSOR%>

same error with agoodbear!

[Yulin-Rog]

Hi all! I'm encountering a problem like this (i keep pressing the "timestamp" button, but it won't trigger anything or make a timestamp but showing up with a this code), anyone meets a similar situation or knows how to solve it? Many thx in advance 🥰

[geekhuashan]

knows how to solve it? Many thx in advan

I was also encountered this problem， how to fix the problem

[growingtreesss]

hi, I tried many youtube links, they didn't work. it just indicates"is not a valid youtube url", does anybody have the same problem?

[abhayprasanna]

Everyone, you have to have @c3founder's YT timestamps script for any of this to work in the first place. And since he has updated his extension to have a keyboard shortcut to add timestamps, you don't even need this SmartBlock anymore. https://c3founder.github.io/Roam-Enhancement/

[natterstefan]

Thanks for making me aware of that change, @abhayprasanna. Works like a charm now!
