Each captioning project we take on undergoes our quality control process which is tiered to ensure that clients get superior quality results in the shortest possible time frame.

Whether open or closed captioning services, our tiered quality control process for all captioning services offered involves a transcriptionist and a highly trained, professional quality analyst specialized in captioning. Both highly experienced professionals will work together to ensure that all closed captions are accurate and quality checked for excellence before being sent out to clients.

Compatible with all major streaming platforms & video players.

Our Process:

We provide closed captioning services in all major languages and for all types of programming. As a company with a team of video content curators and closed captions experts, we are capable of handling all sizes of captioning services, whether large or small.

We ensure that all captioning services we offer are done in-house, from transcription to encoding. This allows our clients to enjoy not only a fast turnaround service but also high quality services they can trust.

The secret to our success lies in the fact that we have taken the time to diligently search out a team with the right skills and dedication to meet all the needs of our customers. From our customer service administrators to our video captioning experts, we have made sure that clients can enjoy unparalleled services while continuously strengthening their trust in top quality closed captioning services.

  • We have also selected the best technicians in charge of our state-of-the-art technology, which is designed to help make your brand more accessible to your target audience.
  • We believe so much in the wealth of skills and experience of our video captioning team. This is why we make sure that they are in charge of the process from start to finish.
  • We also have a team of professional open and closed captioning editors that prides itself on being able to get things done right the first time, leaving no room for error and maintaining the highest quality and accuracy.

Post-production captioning is extremely precise and offers flexible options such as pop-up captioning, open/closed captioning, environmental sounds, and speaker identification.

How it Works:

A transcript with a minimum of 98% accuracy is aligned (time coded) and exported into a caption file (SRT, VTT, TTML, SAMI). The optional service of creating an open caption video permanently burns the captions into each frame of the video file ensuring maximum accessibility regardless of media player.

1. Human Transcription

A quality closed captioning file starts with a highly accurate transcript created by a professional, US-based transcriber.

2. Human Alignment

Combining technology with the human touch, our specially trained aligners know how to create the perfect captions.

3. Human Quality Review

A quality review of the transcript and captions with a fresh set of eyes makes for an excellent result.


Turnaround time is one of the most important elements for any client. ACS has streamlined processes allowing for quick turnaround, while maintaining our high standard for quality.

Our captioning services and staff make use of the latest and most advanced workstation. We ensure that deliverables are returned to you as soon as possible by having multiple editors and captioners work on your video content simultaneously.

One of our skilled writers carefully listens to your media to create a verbatim transcript with a minimum of 98% accuracy. Transcripts are delivered in a text document (.rtf) for easy use in almost any text viewer or word processor.

Unlike other companies,  we are also skilled in rendering specialty script services like:


Combined Continuity Lists

These are most often requested by studios. Production companies may be required to provide continuity lists to facilitate copyright protection. We are here to handle these needs in numerous formats needed.

Dialogue Lists

These are meant to record the conversations between two or more entities. Our company has a team of experienced closed captioners who can deliver top quality results in a variety of formats ranging from the most basic formats to extremely detailed.

As-Broadcast Lists

These are typically detailed scripts with time codes, verbatim dialogue and speaker identification. We can ensure that they are produced at an economical rate during the closed captioning process.
