Accuracy requirement for captions
To ensure the videos you produce and post at Harvard are accessible and conform to WCAG 2.1 guidelines, they should have accurate captions that include proper punctuation, speaker identification, and the identification of sounds other than speech. Professional captioning vendors are excellent resources for providing budget-friendly, high-quality captions with a quick turnaround. While auto-captioning tools continue to make significant progress in accuracy, they are not yet sufficient to meet the accuracy standard of Harvard’s Policy without substantial editing for quality assurance.
Captions for pre-recorded video
There are several approaches to adding post-production captions. Select an approach that’s right for your project based on resources available, timeline, and workflow.
|Professional vendor (recommended)||Fee-for-service||High||Minimal editing required||3Play Media (Harvard’s preferred vendor) or Rev|
|Auto-generated and manual editing||Free||Variable||Substantial editing required||YouTube, Microsoft Stream, or IBM Watson|
