YouTube annotations was launched in June 2008 to allow people get even more creative with their videos and add layers of interactivity, information and, well, good old fun. "Annotations can be a very powerful creative tool and make videos that're engaging, informative and interactive; however it's important to realize that overlay text and hotspots can also interrupt and distract viewers. Not every use of annotation is necessarily a good use - there's an art to it."
YouTube made some important improvements to annotations:
- New annotation editor - overhauled the annotation editor and moved most of the functionality to a new side panel to streamline annotation creation, editing and deletion while leaving the player less cluttered.
- New annotation type - "Title" - Title annotations enable overlaying headlines, videos titles, credits and other "big text" on top of your video, just like you would with professional video editing tools.
- New Font size options lets you select from a combined set of six font sizes.
- New color options - annotations are now available in 16 background colors and 14 font colors.
Also, the Collaborative Annotations feature is now discontinued.
To start annotating, go to My Videos, choose "Annotations" from the drop down menu next to the video you wish to annotate.
