Updates since version 2.25 13
Note that Windows Media Player uses this DirectX functionality to play back video files. If
you have trouble playing or subtitling a particular video file with CaptionMaker, playing
back the problematic file with Media Player will usually correct the problem (because Media
Player can automatically update your system to properly play your file by downloading and
installing updated codecs).
Inserting closed captions to DV & Mpeg2
CaptionMaker inserts closed captions directly into the video data area. When a closed caption
encoded DV video data file is put on DV tape and played back in a VCR, the closed caption
information is output directly from the VCR onto the video signal. Using a laptop computer
with an IEEE 1394 / FireWire interface you can add closed captions to DV video material.
When a closed caption encoded Mpeg2 video data file is copied to a DVD, you get a closed
captioned DVD.
Inserting closed captions to video using a NLE system
CaptionMaker for NLE systems works by putting a 2-D visual representation of the
appropriate closed caption commands into a QuickTime or AVI movie. This movie file is
then imported into a non-linear computer editing system and put on the editing system time
line exactly like other video material. A picture-in-picture effect or a crop effect is then
applied to the imported movie to mask off all but the closed caption image lines, and the
NLE system is used to merge the imported movie with video program material. The resulting
video output from the NLE system is closed captioned. Using this method, no additional
encoder is needed to produce closed captioned video.
This method requires the NLE system to be able to display a line from the visual picture area
into line 21 of the television signal vertical blanking interval (VBI). Video editing hardware
from Avid, Media 100, Matrox and Pinnacle Systems, among others, supports this capability.
Retrieving captions from DV or Mpeg2 video
If you have a DV or Mpeg2 video with closed captions, simply drag the video to the preview
window and the CPC-700NLE will retrieve all the captions with the positional information
and time codes.
