Adding Captions in Quicktime
There are two methods for adding captions in Quicktime:
Method 1
The first method involves creating what is called a Quicktime text track and making it a part of your Quicktime movie. You will end up with one Quicktime movie file that contains audio, video, and your captions. This method requires Quicktime Pro, which can be purchased and downloaded from Apple - external link.
Method 2
The second method involves creating a text track movie as a separate file. The Quicktime audio/video movie and the text track are put together with SMIL (Synchronized Multimedia Integration Language - external link). You will end up with three files:
- The Quicktime movie containing audio and video
- The text (caption) track
- The SMIL file that puts them all together
Advantages and disadvantages
There are advantages and disadvantages to each approach. The first allows you to maintain a single file, making the captioned video easier to distribute, but Quicktime Pro is required. The second approach allows you to easily deliver a captioned and non-captioned version of your movie, but requires an understanding of SMIL.
