Overview
Delivering good quality captions or subtitles can be very costly due to significant manual intervention required in identifying and rectifying a variety of issues that can crop up during captioning process. This becomes more difficult especially when different customers have different technical and quality requirements. Operators end up spending numerous hours and sometimes days dealing with this. This is very expensive and frustrating for teams involved in the captioning chain. If the 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.
CapMate – Captions QC & Correction platform changes all that. It automatically identifies issues and allows users to perform auto correction and export the rectified captions right from within the platform. This saves significant time & cost for the organizations, and allow them to deploy their resources in more value-added tasks.
Features & Benefits

Captioning Service Providers. Deliver your content with confidence and keep your ratings at your top levels with your customers by using CapMate before delivering. You can deliver captions with associated QC reports.
Content Delivery companies. Quickly check the correctness and compliance of incoming captions/subtitles before publishing them on your platform. QC reports from CapMate can be shared with suppliers for quick rectification.
CapMate helps you identify the sync issues very quickly with options for:
- Auto correction: Auto-correct all the issues found with CapMate after which your team members can perform a quick review to finalize the captions. The review can be done in minutes as against hours and days required with complete manual processing.
- Manual correction: Rich manual correction and adjustment abilities are also providing allowing very fine control for certain captions and subtitles. This combined with automatic correction will ensure a fool-proof experience.
Advertisement content may contain product descriptions throughout the content. If Captions are displayed on top of this description, it severely reduces the value of advertisement spot for the advertiser. They would like to ensure that all the important information is clearly visible to the viewers.
Identifying these locations manually is a very time consuming and an error prone process. Both the captioning companies and content providers run the risk of publishing a faulty content in case such locations are missed.
CapMate automatically identifies all the overlap locations and presents them to the user for review and correction. Users can then take corrective measures within CapMate itself, saving them numerous hours and business goodwill.
- Duration. Minimum and Maximum duration for which the caption/subtitle will be displayed.
- Characters per line. Maximum number of characters to be displayed per line. Too many characters can make it difficult for users to comprehend.
- Words per minute. Maximum number of words to be displayed per minute. Using too many words will make it difficult for users to comprehend.
- Successive captions overlap. There must be certain gap between two successive captions for good user experience.
All the above (and more) can be validated and rectified with CapMate in a time & cost efficient manner.
Once done, you can export the corrected captions files with all the curse words masked with the characters of your choice.
- Navigate and preview the QC results with associated audio/video
- Make manual corrections for timing, captioning text and associated styling
- Export the corrected captions/subtitles in their publishing format

Customer Testimonials
Heiki Mannik
Coordinator of Digital Archiving, Estonian Public Broadcasting
Pulsar is an important addition to our infrastructure and will help us obtain higher operational efficiencies from our content workflows. We looked at major QC players in the market and selected Pulsar because of its high performance and accuracy of results. As Public Broadcaster, we verify new material coming daily from production and will use Pulsar for that but even more important role of Pulsar would be to keep an eye on large volumes of old archive material being mass-digitized from analogue tapes with its QC reports
Michael Mallozzi
VP of Broadcast Engineering & System Design, AMC Networks
Given our positive experience with our initial Pulsar installation in improving the quality of the content in our file-based workflow, as well as Venera’s ongoing support and responsiveness to our requests since our first Pulsar installation in 2013, we chose to expand our QC operations with additional Pulsar systems, which we have found provide us the best value and ROI.
