You can verify that closed captions are being properly handled by DeckLink Extreme by
digitizing an analog video broadcast signal containing closed captions and then playing it back
into a TV receiver to display the closed captions. When this works successfully choose the NLE
preference panel in MacCaption and select Blackmagic DeckLink Extreme in the "Set NLE
Values to" pull down menu. In MacCaption under File/Export use "Black 720x486 NLE Movie
with Closed Captions" and generate a QuickTime movie containing just closed captions. To
superimpose closed caption data onto an actual video image, place the QuickTime movie onto a
video track and crop the video keeping just the close caption lines that are located near the very
top of the video frame.
MPEG-2 (DVD) 720x480 Video
You can add captions to the data area of MPEG-2 video (for DVD) directly without using a NLE
system.
Note: To caption a DVD video, you have another choice. You can export a .scc file from
MacCaption and bring it to DVD Studio Pro (DSP), Sonic or Scenarist DVD authoring
system. The authoring system will add the captions to the caption track of the DVD.
