Size of Youtube Video Embed is not correct

The Size is not correct

Agree it do not look good. 

What Embed size are you other guys using to make it look good?

Could be column width?

Typically a YouTube video is 640x360. So maybe that is what should be used?

I have same issue, the video player width/height on embedded videos does not display correct size.

In video settings i have 640/360 (same as the embbeded youtube size), but it still doesn't display correct size.

Are you talking about the black space on the left and the right?

Mainly I'm talking about the height, even if i increase the video display height it won't take the change when viewing video, it stays the same size on the display window. The height of the video display looks shrink down.
