Importing Captions
Retrieve Captions from a DV Movie
(Real Time Decode over FireWire)
MacCaption will display and decode video and its associated closed captions, Program Name
and V-Chip information coming in over FireWire. To decode closed captions from a DV movie
over FireWire:
• Attach a FireWire device such as a DV camera or DV VCR to the computer FireWire
port and turn it on.
• Under the File menu, choose Real Time Decode and a Decode Window will appear.
• Start sending a video source to the FireWire port and watch the video in the Decode
Window.
• Click the Show Captions option to see the closed captions in the video.
• Check the Save Captions option to begin saving the closed captions.
• Uncheck the Save Captions option to stop saving closed captions.
Many Digital Video cameras and VCRs will convert an analog signal to a digital FireWire
signal. To watch a real time TV broadcast with your computer, connect the analog video and
audio output from a VCR to the analog video and audio input of your DV camera or DV VCR
and connect the Digital/FireWire output of your camera to your computer. In the MacCaption
Decode Window you can watch a television broadcast with its associated closed captioning.
If Closed Captions do not appear, verify that
• Your analog or DV video signal actually contains closed captions. You can do this by
playing your analog or DV video into a TV that has its closed caption decoding feature
enabled. If you are using DV you can verify that your DV record/playback device is
closed caption capable by recording a TV broadcast that contains closed captions and
then playing it back into a TV over the composite video input and watching for closed
captions.
• Your analog to DV converter hardware is capable of converting an analog video signal
that contains closed captions into a DV data stream that contains closed captions.

lines.
