Quality and Accuracy

Without exception, all work is done in the U.S. by native English speakers capable of accurately capturing the cultural and linguistic nuances of your content. Having a staff of more than 1,500+ transcriptionists gives us the flexibility to assign complex or technical content to transcriptionists with a discipline-specific expertise or a familiarity with a certain accent.

Your transcripts also undergo a stringent, multi-step quality assurance process, ensuring that the quality is as good as or better than manual transcription or court stenography.

Account System

Our robust account system lets you upload and manage files, monitor job status, preview and download caption, subtitle, and transcript files, manage users, set up billing, use video search and clipping tools, and set up an interactive transcript or other video plugins.

Caption Editor

Although rarely necessary, your account includes a caption text editor that allows you to quickly make changes or redactions to your captions after they have been processed. Your edits propagate to all captions and transcript outputs, including video plugins that have already been published.

Caption Placement

As an option, we provide vertical caption placement through an automated process that repositions captions to the top of the screen whenever necessary to avoid obstructing onscreen text. This process complies with FCC rule 47 C.F.R. § 79.1(j)(2).

Open Captions and Encoded Closed Captions

Although captions are usually output as a separate file, in certain cases it is necessary to output a video with open captions burned in or closed captions that are embedded as a track. This results in a self-contained captioned video that can be distributed as a single asset. Open captioning and caption encoding are optional features built into the account system.

Integrations with Video Platforms and Lecture Capture

3Play Media integrates with most popular video platforms and lecture capture systems to allow seamless file transfer, captioning automation, and connectivity with our video plugins.

Speaker Identification and Transcription Settings

Transcription settings let you control how your files are transcribed and can be set on a file by file basis or applied to an entire folder or project.

Technical Glossaries

Keywords, a technical vocabulary, and special instructions can be preloaded on a file by file basis or applied to an entire folder or project.


Our staff of 1,500+ transcriptionists is capable of processing large volumes of content very quickly. Standard turnaround is 4 business days.
