4:3 Standard

This is the aspect ratio used for movies in the “silent era” and used nowadays for film production under the nomenclature Super 35. 4:3 is close to the 1.37:1 aspect ratio definite as a standard after the introduction of optical sound-on-film. When cinema audience dropped, Hollywood produced widescreen aspect ratios in order to distinguish the movie industry from television

16:9 Standard

16:9 is the worldwide standard format of HDTV, non-HD digital TV and analog widescreen TV PAL+. Several digital video cameras have the potential to record in 16:9, and it is the only widescreen aspect ratio native in the DVD. DVD producers are able to also choose to show flat wider ratios such as 2.39:1 and 1.85:1 within the 16:9 DVD border by hard matting or adding black bars within the image itself.
