Easy YouTube plugin that controls width of individual videos?

Hello,

I am looking for a plugin that will make it very easy for beginner users to embed YouTube videos in their posts, and also allow them to control the width of those videos. Ideally this plugin would:

– Use a very easy method to embed videos — either very easy shortcuts or better yet a point and click interface like the WP image uploader/editor

– Allow the user to set the width of the video, but without having to calculate the correct aspect ratio (again, like the ‘scale’ function in the image uploader/editor)

– Allow the user to set the video’s alignment easily

– Have the ability to add a caption, like with an image

My clients are not web savvy at all so I’m trying to find a solution that makes inserting videos as easy as it is to insert and format images. I’d appreciate any recommendations. Thanks!
