Captioning FAQs

• What is closed captioning?

You can learn more in our article, The Ultimate Guide to Closed Captioning.

• What is Predicted Caption Accuracy?

  Predicted Caption Accuracy is a proprietary feature from 3Play Media that uses Artificial Intelligence (AI) to estimate the quality and Word Error Rate (WER) of a machine-generated caption file before a human has reviewed it. This allows you to set accuracy thresholds to either post back ASR or automatically upgrade to human review.

• Do you offer caption placement?

  We offer automated and manual caption placement services to help you meet FCC requirements cost-effectively.

• What is your accuracy for captioning/transcription?

  We guarantee a minimum of 99% accuracy and our actual measured accuracy averages 99.6%. We achieve this level of accuracy the first time and every time, eliminating the need for review and rework. This article describes the effort we invest to make sure we always achieve at least 99% accuracy.

• Do you split media files among numerous transcriptionists?

  No. Many vendors chop up each video into micro segments that are split up among numerous transcriptionists. This creates inconsistencies and quality issues. We use a single transcriptionist to work on a file from beginning to end. This ensures that the transcriptionist has the full context of the content to better identify proper nouns and that the transcript contains completely consistent standards and spellings.

• What differentiates 3Play Media’s transcriptionists?

  Our transcriptionists are a critical part of our process at 3Play Media, and are treated as such. All transcriptionists go through a rigorous certification process. They are unique individuals who are detail-oriented, have a strong grasp of English grammar, and are eager to help your content be the best and most accessible it can be.

• What if I need a truly flawless transcript?

  If you need a flawless transcript, we offer a full review option. This typically increases accuracy to 99.9%. Another option is to review and edit the files yourself, using the caption editor.
