Exporting 16:9 Anamorphic Video

Instead of outputting to tape, you may want to export your 16:9 anamorphic sequence to a media file for online distribution or DVD authoring. Here are some common export file formats and the commands used to create them:

Unlike output to standard definition tape, which may require letterboxing to fit in a 4:3 aspect ratio, there is no need to letterbox media files because they can have any dimensions you want (in this case, 16:9).

Calculating the Dimensions for an Exported 16:9 QuickTime Movie

The dimensions of your exported movie depend on several factors, including any file size limitations and height or width constraints. For example, if you are producing a website in which every movie has a width of 320 pixels, regardless of height, then the width will determine the height. To calculate the dimensions of your movie, use the following formula, where aspect ratio is always 16:9:

aspect ratio = pixel width/pixel height

For example, if you want the width of your movie to be 320 pixels, the formula for pixel height looks like this:

16/9 = 320/pixel height

Or, rewritten:

pixel height = 320/1.7777

In this case, your final movie dimensions should be 320 x 180 pixels.
