Hello!
The video snippets block lets you play video files uploaded to an attachment field. You can preview a whole video, or specify start and end times by selecting duration fields containing timestamps.
We’ve been using it internally for meeting recordings and user research sessions. In these bases, we have the videos stored in one table, and we have a second linked table (“Nuggets” in the screenshot below). The records in this second table act as bookmarks into specific parts of the videos.
→ Click here to join the beta. Once you click that link, the “Video snippets” block will be available in the list of blocks when you go to install a block.
P.S. The source code for this block is available here, so you can remix it if you’re in the custom blocks beta.
