Printing Captions to Tape with NLE

CPC MacCaption and CaptionMaker can add captions directly to a video tape using your NLE system. Once you know the exact settings either for the known compatible NLE systems or, using our caption encoded calibration movie, you can export a caption encoded black movie for your SD 720x486 project.

Typically, this method of NLE captioning is used to print closed captioned Digital Betacam and Betacam SP masters directly from your timeline. But it can be used to caption any other SD videotape via your NLE capture card.

Follow these simple steps to closed caption your SD 720x486 NLE project:

Step 1. Once you have done all your caption preparation inside our CPC software, you will have to export a caption encoded blackmovie from either MacCaption NLE or CaptionMaker NLE.

To export a caption encoded blackmovie for your NLE system follow the instructions in these video tutorials.

Step 2. Launch your NLE application (Avid, Final Cut Pro, Premiere, etc.) and import our caption encoded blackmovie into the asset bin. (Avid user: You must import 720x486/Non-Squared/Upper Field First)

Step 3. Make sure that your video timeline or sequence settings are 720x486 non-squared, upper field first, uncompressed codec. Below is an example of what your NLE sequence should be set to in Final Cut Pro.

Blackmagic Decklink users: You must optimize your settings in order to caption with our software solution. For a complete list of BlackMagic settings in a Final Cut Pro system click here.

Step 4. Place the caption encoded blackmovie into your video timeline on top of the video. For example, in Final Cut Pro, if your video material is in "V1", place your caption encoded blackmovie on "V2".

Step 5. Crop the caption encoded blackmovie on the timeline to reveal the video material below it. The caption encoded blackmovie contains a special code at the top of the screen that contains the closed caption information. To marry your video material and the caption encoded blackmovie you must crop the bottom of the blackmovie and maintain the code at the very top. Typically, video editors crop up to 98% of the blackmovie from the bottom up. However, cropping the caption encoded blackmovie past "action safe" on the top will suffice (see Fig 3).

Step 6. Connect the video output of your NLE capture card to a NTSC television set. (any Composite, Component, SDI, S-Video outputs will work)

Step 7. Turn on your caption decoder to CC1 on your NTSC television set. (consumer grade TVs may require a remote control to turn on the caption CC1 decoder)

Step 8. Play your new caption encoded video from your timeline out to your television. Spot check the captions to make sure they are in sync with the video.

Step 9. Print to tape via your NLE capture card to your VCR.
