Is 720×480 a 16×9?
For anamorphic standard definition video, the frame size will typically be either 720×576 (for PAL) or 720×480 (for NTSC). To convert these into widescreen 16:9 non-anamorphic square pixel formats, we stretch them horizontally until the SAR becomes a 16:9 aspect ratio.
Is CinemaScope anamorphic?
CinemaScope is an anamorphic lens series used, from 1953 to 1967, and less often later, for shooting widescreen films that, crucially, could be screened in theatres using existing equipment, albeit with a lens adapter.

What does 1080p stand for?
1080p (1920×1080 progressively displayed pixels; also known as Full HD or FHD, and BT. 709) is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the p stands for progressive scan, i.e. non-interlaced.
What format is 720×480?
720×480 is NTSC anamorphic standard-spec format for DVD and standard def BluRay. Both formats are interlaced. The display aspect ratios allowed after encoding are either 4:3 or 16:9. 720×480 is the frame format prescribed for 16:9 display video in DVD or SD-BluRay.
What does 720×480 mean?
Standard-Definition is 720×480 (again, 720 pixels across and 480 pixels tall) in North America. By contrast HD has a resolution of either 1280×720 or 1920×1080, which equates to more pixels per square inch, allowing for much more detail than SD.
Which lens is used in CinemaScope projector?

Projectors and cameras Both a projector and a camera use a convex lens to bring light to a focus on a screen or piece of film. This is called a real image; light actually reaches the screen or film. Figure 2: The thicker a convex lens, the more it bends light.

Why is a 720×576 frame not a 4-3 image?
A 720×576 frame is not actually a 4:3 image. Standard (non-widescreen) provides a frame size of 720×480 (DV-NTSC) or 720×576 (DV-PAL) using appropriate Rec.601 pixel aspect ratios. Thus, according to the previous calculations, these frames contain a visual image which is slightly wider than TV’s 4:3 display aspect ratio.
What is the aspect ratio of widescreen video?
The new widescreen format (HDTV, anamorphic DVD’s, wide DV, etc.) has a 16:9 display aspect ratio. Frames are encoded at the same size, but with an appropriately scaled pixel aspect ratio: 525-line (NTSC): 10:11 / 4:3 * 16:9 = 40:33. 625-line (PAL): 59:54 / 4:3 * 16:9 = 118:81.
