As you work your way through the digital story telling project, when your first draft of the video is ready and processed and saved as a file, you can upload it to YouTube, which will ease embedding it into a blog post.
This short video walks you through the process of how to upload your video to YouTube once you have a YouTube account. On another note, if you don't already have a YouTube account, you should consider having one to save your favorite YouTubes. YouTube also enables organizing your favorites into categories.
For the digital story telling project, you will be embedding in your blog two drafts of your video, an early draft and a final draft. In addition to using YouTube to upload videos, there are other video sharing sites, and you can also use Google Doc. If I find a good tutorial on how to use Google Doc for this process, I will post it.
