EDIT: Instagram appears to be messed up as well. Examples in comments.
This could be a simple fix that I can't figure out, but using the embed code provided by Facebook, the videos always seem to get cut off at the bottom. Increasing the height of the iframe doesn't do anything.
Example 1 (Montana Man Attacked By Bear)
Embed Code:
<iframe src="https://www.facebook.com/plugins/video.php?href=https%3A%2F%2Fwww.facebo..." width="400" height="400" style="border:none;overflow:hidden" scrolling="no" frameborder="0" allowTransparency="true" allowFullScreen="true"></iframe>

Example 2 (Monkey and Cat)
Embed Code:
<iframe src="https://www.facebook.com/plugins/video.php?href=https%3A%2F%2Fwww.facebo..." width="400" height="400" style="border:none;overflow:hidden" scrolling="no" frameborder="0" allowTransparency="true" allowFullScreen="true"></iframe>
