Now that the standard YouTube format is for HD video formats, they are based on dimensions of 16:9 (width to height).

So for in-content videos in blogs I am going with 240p format which I think is 427 x 240 pixels. But the YouTube player has a control bar below the video of 25 pixels in height. So the dimensions in the code needs to be 427 pixels wide by 265 pixels deep.

And the next size up is 360p (640 pixels x 385 pixels).

Is this right?
