Some high-level consumer cameras now offer a more "real" 16:9. When using one of these converters, you will use 16:9 settings in your encoder, since the picture is really 16:9 squeezed into the 4:3 format. These lenses cost about half of a normal miniDV camera. You can however make a widescreen movie with almost any miniDV camera by using a special 16:9 Widescreen Converter (for example by OPTEX or Century Optics) which optically compress the image in the horizontal direction. So instead of the image being made wider, this method is in fact a crop from 4:3 so you are actually losing angle of view! It has no value since what it does is to simply mask out the bottom and top of the image, while the image itself is still 4:3. Some consumer miniDV cameras feature a "widescreen" option, but this is a feature with no benefit. If your source is a miniDV camera then it is probably always 4:3. Of course, in order to have widescreen image, your source video must be widescreen. Most encoders provide an option to set this flag:įor an example, see the following screenshot from the TMPGEnc encoder: A 16:9 feature will be letterboxed on 4:3 TV (Image 3) or Pan & Scan (Image 1).Īn MPEG file carries within it a parameter for the aspect ratio informationĪnd is a flag set by the encoder. 16:9 is the aspect ratio of a widescreen TV (Image 2). Both aspect ratios use the same picture size, however the 16:9 (widescreen anamorphic) image is horizontally compressed on DVD and then stretched by the DVD player when viewing.Ĥ:3 is the aspect ratio of a normal TV (Image 1). "Normal" or "Full Size") and 16:9 ("Wide Screen"). There are two aspect ratios supported by DVD: 4:3 (also called
