  • Having used CaptionSync for over two years now, we have found it to be a very flexible and cost effective tool for our productions.  As the creative media department it has been part of our remit to find the best forms for interactivity and accessibility for the wider university.  Being able to upload batches of files to CaptionSync and have them returned swiftly has enabled us to deliver video and audio content with subtitles and transcription to the wider university and the public.
