Just as another quick update concerning our group project, I figured something out that I really wanted to know how to do.
Normally, when I just want to embed a video from YouTube, I grab the embed code, and then insert it into the "Edit HTML" section of the blog editor. However, sometimes the video is too big, and actually goes outside the blog post, which always looks really tacky. I had this problem again when trying to add a post to our group's Backpack 2.0 blog website. I wanted to embed a video in one of my posts (namely my post about Dropbox) and the video was always too wide, and looked really bad on the website.
However, I did some experimentation, and found out how to shrink the movie to fit the blog! In the embed code, there is a place at the beginning that determines the height and width of the video box, AND there is a place at the end of the embed code that determines the width and the height of the box. If you go in and change those heights and widths to smaller values, you get a smaller video window.
Here's an example of a video without doing the height and width change:
And here it is again with the height and width changed:
Ouila! Much better!
