How come my Youtube video is stretched out?

[Jay]

I just started using an HD Panasonic camera, but when I edit I upload them to Youtube after editing them in Windows Movie Maker, I noticed there is this REALLY unattractive stretching of the video and I have no idea how to fix it!

Here's the video:



As you can see it is stretched from side-to-side, and there are some black bars above and below it.

I've tried adding the tags (i think it's yt&4:3 or something like that, and 16:9) but they did not work.

Help?

You have to make sure you are filming and editing in the same resolution. For example I film in 16:9 and edit in that same format. I know this post is kind of old. Just wondering if you figured it out?
