I WOULD LIKE TO ADD VIDEOS TO TABLES. HOW WOULD I GO ABOUT DOING THAT?

Are you looking to embed the videos in an <iFrame> , create a link to the video, or attach the file of a video so the user can download and watch?

embed the video in an <iframe> 

You have to use script to do this because QuickBase greatly restricts what HTML tags are allowed in text fields. 

Here is a working demo using the IOL technique:

Stooges Videos

Pastie Database

You can add your own video to the demo:

Notes:

(1) The code uses HTML backticks for string interpolation.

Can I attached a video like I do images?

Yes, although at some point if the file attachment is too large the upload may fail.

Is there a way to display same video in mobile view.
