title: How to add multiple notes/tags to a video at different time points?
body: <p>On my website, I want users to upload a video and add multiple notes during its playtime at different time points. I have seen this feature on YouTube where users can jump into a certain time point in the video. Like a video index.</p>
  <p>Is this achievable through JavaScript or any other mechanism? I try to search online with the term &quot;video tagging&quot;, &quot;labeling videos&quot;, &quot;annotating videos&quot; but couldn't find useful direction on where to start.</p>
  <p>Appreciate any guidance or thought on how to achieve this task.</p>
