Along with words, photos and links, you can also add a video to share on Twitter. One way to do this is by sharing a link to the video from a popular media-streaming site like YouTube. Another is by uploading your own video through the Twitter app on your smart phone.
How to tweet a YouTube video
Go to www.youtube.com. Click in the search bar at the top of the screen, type in something you’re looking for, and either click a suggested search term or press the “Enter” key on your keyboard.
Find the video you’re looking for and click on it to go to its page – as if you are going to watch it.
Underneath the video, there is a Share tab that lists all of the social media websites that you can share the video to. Click it, and then click the Twitter logo.
A new window will pop up with a link to the video and a title. (Twitter may also ask you to log in, so go ahead and do that.) You can click inside the composition window and type in anything else you’d like to say (given it’s within the 140 character limit), and then click Tweet to tweet it to your followers.
Tweet Your Own Videos
You used to be able to upload videos to Twitter by using third-party websites such as Twitpic. While most of these websites don’t work anymore, Twitter has now built video-tweeting functions right into their mobile applications.
Just download the Twitter app for your smart phone (either your iPhone or your Android-powered phone), record a video that you want to share, edit it as you’d like, and then write the rest of your tweet. If you’re using an iPhone, you can also edit and tweet a video that’s already on your phone (without having to record it yourself).
Note that videos tweeted this way cannot be more than 30 seconds long.
