The QuickTime Options Window/Text Attributes tab contains:
- Set Font button: This button allows you to select the font used in processing the caption for transmission or capture. Font face, size, bold, and foreground color can be selected.
- Justification drop-down menu: The justification control allows you to select left, center, or right alignment.
- Capture Offset field: The Capture Offset field allows you to select the default offset, in seconds, that appears when the Offset and Save function is invoked during a capture process. Note that the timecodes used during capture are simply system times, since there's no other reference. But when multimedia files are played back, there's an implicit starting time of zero. Offsetting the captured file allows you to get the timing correct for the final on-demand product.
- No CC Msg field: The No CC Msg field lets you set the short message that is sent to the live stream when no captions are detected at the input filter. This is only relevant for those output filters that can handle real-time output streams. Currently QuickTime has no real-time component.
