Currently, adding a YouTube video to your post is fairly easy, but it still requires several steps of work: If you don't have the embed code already, you'd have to open a new browser window or tab, go to YouTube.com, search the video, and play the video to make sure it's the right video. Once you copy the embed code, you come back to your Blogger post and manually insert the code in your post.
Blogger just added a new Blogger in Draft feature that makes this process a lot easier. You don't have to open another tab or window; from your post editor, just click the Insert a Video button in the toolbar. In addition to the already existing Upload tab, you'll now see two new tabs: From YouTube and My YouTube videos.
In the From YouTube tab, you can search, browse, and play back YouTube videos all within the interface. If you have your own videos on YouTube, My YouTube videos tab will show them as well.
Once you choose the video, click on Select to insert the video to the post. You’ll then see a thumbnail image for the video, which you can move around in the post by drag-and-drop.
By the way, in case you didn’t know, it’s as easy to add a video to your blog from YouTube as it is to add a YouTube video in Blogger. While you are watching a YouTube video, click “Share” button, and you will see Blogger as one of the places you can share the video to. Click on Blogger, and you’ll see the familiar BlogThis! mini post editor -- all you have to do is to select a blog (if you have more than one blog, that is), fill out some content, and then Publish the post. Enjoy video-blogging!
