After you've done the one-time configuration you're ready to submit program for captioning.
Step 1: Submit your material to CaptionSync
Make sure you have checked Digital NLE Captions in the Advanced Settings. If you want us to review the caption results before generating the NLE movie, please also check Result Review in Advanced Settings (prepaid accounts will need to have purchased Result Review minutes). When you select Digital NLE Captions you then need to enter the NLE Timecode, NLE Row, NLE Column, and NLE Codec you determined in steps 1-3 in the one-time configuration. Check the Save above as default checkbox if you would like these settings saved as default.
You can also select Review Transcript before Captioning in Advanced Settings if you would like to review and approve the transcript from the transcriber before we create the caption files.
Step 2: Receive a zipped black MOV which matches the codec you’ve requested
The Digital NLE caption file will typically be emailed within 15 minutes of receiving your other caption files. You can also download it directly from our website on the Details page corresponding to your submission.
Step 3: Render and print-to-tape
Unzip the file to yield a 720×486 black video with closed caption data at the top. The caption data looks like tiny dashes near the top of the video. This video file is then imported into the NLE system and put on the timeline along with the original video. A crop effect is then applied to this imported video to mask off all but the closed caption image line, then the imported video is merged with your original video.
Then when you transfer the merged video to NTSC via the NLE hardware (not FireWire) the caption data from Row 0 or Row 1 of 720×486 video is transferred to Line 21 of NTSC video.
A summary of the steps is below:
Import our caption encoded black movie into the asset bin (Avid user: You must import 720×486/Non-Squared/Upper Field First).
Make sure that your video timeline or sequence settings are 720×486 non-squared, upper field first, uncompressed codec.
Place the caption encoded black movie 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 black movie on “V2”.
Crop the caption encoded black movie on the timeline to reveal your original video below it. The caption encoded black movie 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 black movie you must crop the bottom of the black movie and maintain the code at the very top. Typically, video editors crop up to 98% of the black movie from the bottom up. However, cropping the caption encoded black movie past “action safe” area at the top is fine.
Connect the video output of your NLE capture card to a NTSC monitor with caption decoding capabilities (Composite, Component, SDI, S-Video outputs will work).
Turn on your caption decoder to CC1 on your NTSC monitor.
Play your new caption encoded video from your timeline out to your NTSC monitor.
Print to tape via your NLE capture card to your tape deck.
