Most comprehensive QC & correction for captions/subtitles
Delivering good quality captions or subtitles can be very costly due to significant manual intervention required in identifying and rectifying a variety of issues with traditional closed captioning software. This becomes even more difficult especially when automated subtitling tools are used or different customers have different technical and quality requirements. Operators end up spending numerous hours and sometimes days dealing with this. If the Caption or Subtitle QC is neglected and not done properly, then this can pose serious brand risk in the current environment where viewers expect highest quality of experience.

This saves significant time & cost for the organizations that use automated subtitling or captioning software, allowing them accurate delivery of captions as well as deploying their resources in more value-added tasks.
