Closed Captioning with CaptionSync allows you to request multiple broadcast formats. This article shows how.
True broadcast outputs such as SCC, CAP, and ASC files are for line-21 NTSC television and they follow the EIA-608-A spec (officially defined by the Consumer Technology Association as CEA-608-E R-2014). This means they do not support the wide variety of characters that may be present in web or subtitle files, and that there are also several appearance restrictions, like the limit of 32 characters per line.
The easiest way to tell is to look for Broadcast Constraints noted on the Summary Sticky on New Captioning Submission or New List of URLs page:
You can also tell whether you have broadcast outputs selected on the Captioning Submission page (New Captioning Submission under the Caption/Transcribe tab). Click the Advanced Settings button and see if there is a message at the bottom about the line length being locked to 32 character (a broadcast limitation).
You can remove the broadcast restriction by deselecting the broadcast outputs (such as SCC, CAP, ASC). Make sure to check the Save Above Settings as Default box, if you want these changes applied to all submissions going forward.
