Add a video
To add a video to your blog post, click the film strip icon in the Post Editor toolbar above where you compose your blog text. A window appears prompting you to 'Add a video to your blog post.'
Click Browse to select the video file from your computer that you'd like to upload. Note that Blogger accepts AVI, MPEG, QuickTime, Real and Windows Media files and that your video must be less than 100MB in size.
Before uploading your video, add a title in the 'Video Title' box and agree to the Terms and Conditions (you'll only have to do this the first time that you upload a video with Blogger). Then click UPLOAD VIDEO.
While your video uploads, you'll see a placeholder in the post editor showing where your video will appear. You'll also see a status message below the post editor letting you know that your upload is in progress. Depending on the size of your video, this usually takes about five minutes. When it is complete, your video will appear in the post editor.
