The HTMLVideoElement interface's read-only videoWidth property indicates the intrinsic width of the video, expressed in CSS pixels. In simple terms, this is the width of the media in its natural size.
See HTMLVideoElement.videoHeight > About intrinsic width and height for more details.
An integer value specifying the intrinsic width of the video in CSS pixels. If the element's readyState is HTMLMediaElement.HAVE_NOTHING, then the value of this property is 0, because neither video nor poster frame size information is yet available.
