You can't upload videos directly to Bramble but you can easily share links to them. Simply copy the link and then return to the Bramble notebook and press cmd+v or ctrl+v to share the link. It will appear as a clickable link in the top left corner for the other user to click on. This enables you to share links to other websites too. If you want to mark up content from another website, take a screenshot and paste it into Bramble.
You can share links to videos or other websites.
