The display height is the height of the visible frame on the DVD-the frame after cropping away black bars. The storage width is the width of the visible frame on the DVD (almost always 720) and the display width is 854 (storage height of 480 times 16/9). For details, see the Macroblock Appendix.) (Those height and width values are only approximate. The visible frame height (when you remove the letterboxing) just gets shorter and shorter to match the aspect ratio-480, 460, and 360, consecutively. So whether a movie has an aspect ratio of 1.78:1, 1.85:1, or 2.35:1, it is always going to displayed 854 pixels wide. To make it “shorter” the top and bottom are matted with black lines. 480 is too “tall” for films wider than 16:9. When anamorphic DVD content is stretched for viewing on a widescreen TV, it always stretches to 854*480. So I’m going to repeat this with a few different wordings. To cope with this, black bars (letterboxing) line the top and bottom of the picture. When this is stored on a DVD, it too is given the 16:9 aspect ratio flag. One popular aspect ratio is 2.35:1, which is quite a bit wider. Of course, a lot of movies are wider than 16/9. Standard TVs use an aspect ratio of 4/3 (1.33:1).ĭVD video has an “aspect ratio flag” which tells the DVD player how to distort the picture stored on the DVD to recreate the original film aspect ratio. This is the native aspect ratio of widescreen TVs. One common widescreen aspect ratio is 1.78:1, or 16/9. It’s not wide enough for movies and widescreen TV, and too wide for standard TV. That means it’s 1.5 times wider than it is tall.īut video isn’t meant to be seen with a 1.5:1 aspect ratio. Aspect RatiosĪspect ratio is the width, divided by the height. DVDs are stored with a 1.5:1 aspect ratio. Notice how it’s distorted? That’s the anamorphic part. This is what the image stored on an anamorphic NTSC DVD looks like (for information on non-anamorphic DVDs, see the Hard Letterboxing Appendix): (See the PAL appendix for the differences.) I’m in North America so I’ll be using NTSC numbers in my examples. Anamorphic DVDsĪn image is stored on a DVD at 720 480 (NTSC) or 720576 (for PAL). You can enable anamorphic support via the Picture Settings tab on the main window. This produces that nice, big, widescreen image. Note that it preserves the full height of the image stored on the DVD:Īnamorphic in HandBrake means encoding that distorted image stored on the DVD, but telling the video player how to stretch it out when you watch it. Here’s the display size of a movie that’s been stretched horizontally – HandBrake’s default. Notice how the width stays the same as what’s stored on the DVD, but the height is reduced: Here’s the size of a movie that’s been squeezed vertically. One shrinks the image, and one expands it. To restore the proper shape, you can either squeeze the picture vertically or stretch the picture horizontally. Instead of being truly widescreen, it’s squeezed into a narrower frame. Here’s the size of a movie stored on a DVD. These are scaled down 50% in size, in case you couldn’t tell.
