All the videos has a default size. But this default size is not occupies all the size I have for the video. In most of the time there are much space at the right.
Now I use the DarkLiquid Water theme and the resolution of my screen is 1024 x 768. With the object that the videos occupies all the space that I have, I modified the resolution to 635 x 536 but with other resolutions of the screen the video is bigger than the space that I have reserved for it.
My propose is a plugin that detect the resolution of the screen and resize the videos depend the resolution. The admin can modifier different size of the video for different resolutions of the screen
