CaptionSync is an automated system that will ingest and process all requests submitted to it. Unfortunately, we are unable to detect if you have submitted the same media file more than once, as there isn't really a good way to detect duplicates: we cannot base it on the Description provided, or the Filename (we receive many submissions with titles like "Chapter1"). Therefore, our system will not monitor your account for duplicate requests, and each new submission will be processed, transcribed, and captioned as a new request.
If you're making requests via AST-Link, or 3rd-party integrations, please ensure you monitor the progress of the submissions by opening the Status of Submissions page, on the relevant account. If you detect duplicates in the submission history, or requests with the wrong duration or settings, please cancel them immediately. Once transcription starts, it's no longer possible to cancel a request.
