Subtitle Localization for Global Life Sciences Communication
In the life sciences sector, video-based content plays a vital role in educating patients, training clinical staff, and supporting regulatory submissions. As organizations expand into multilingual markets, subtitling services have become essential for ensuring accessibility, comprehension, and compliance across regions.
High-quality subtitles improve engagement, reduce language barriers, and meet accessibility mandates such as WCAG and Section 508. From clinical trial training videos and SOP modules to medical device walkthroughs and patient-facing communications, subtitling supports consistent global messaging in a cost-efficient, scalable format.
At Sesen, we specialize in multilingual subtitle localization for regulated industries. Our expert linguists and multimedia engineers work together to deliver subtitles that are not only linguistically accurate and culturally appropriate, but also compliant with the strict standards of global health authorities including the FDA, EMA, and PMDA.

Types of Subtitling Services We Provide
Sesen offers a full spectrum of professional subtitling services tailored for the diverse needs of life sciences organizations. From improving accessibility to supporting global video distribution, our solutions are built for accuracy, regulatory compliance, and multilingual scalability.
Standard Subtitling
Designed for clear viewer comprehension across languages, standard subtitles provide time-synchronized translations of spoken content. Ideal for patient education, clinical training, and internal communication videos, they maintain clarity while preserving technical accuracy.
Closed Captions (CC)
Closed captions display not only the spoken dialogue but also relevant non-speech elements (e.g., speaker labels, tone cues) to support accessibility for hearing-impaired audiences. CC is essential for meeting Section 508 and WCAG compliance in digital health content.
SDH (Subtitles for the Deaf and Hard-of-Hearing)
SDH goes a step further than standard captions by including speaker identification, background sounds, and audio cues. This format is widely used for regulatory and patient-facing video assets that must meet enhanced accessibility standards across markets.
Real-Time Subtitling
Sesen provides live subtitling for webinars, virtual training sessions, and medical conferences. Using a combination of trained linguists and AI-assisted tools, we deliver low-latency, high-accuracy subtitles to support real-time multilingual engagement.
Multilingual Subtitling
We support subtitle localization in 150+ languages for global eLearning programs, regulatory video submissions, product launches, and CRO communications. Each version is linguistically and technically aligned for regional clarity and compliance.
Our Subtitle Localization Workflow for Life Sciences Content
Sesen follows a structured, quality-driven subtitle localization process to ensure that every subtitle track is accurate, compliant, and accessible—whether for regulatory review, patient education, or global training initiatives. Our workflow is optimized for technical precision, linguistic clarity, and viewer readability.
Source Script Transcription & Timecoding
We begin by transcribing the original audio and applying frame-accurate timecodes, ensuring that each subtitle segment aligns perfectly with the speaker’s pacing and on-screen visuals. This provides a reliable foundation for multilingual subtitle production.
Scientific & Medical Terminology Translation
Our linguists—specialized in pharmaceuticals, biotech, medical devices, and CRO workflows—translate the content using accurate, domain-specific terminology. We reference client glossaries and apply in-market standards to ensure regulatory alignment across languages.
Subtitle Editing for Clarity and Compliance
Subtitles are adapted for brevity, reading speed, and character limits, ensuring they are concise without losing critical meaning. We also enforce language-specific compliance rules for subtitles intended for regulatory submissions or accessibility audits.
Visual Timing & Formatting Optimization
Our engineering team fine-tunes subtitle timing, line breaks, and positioning to improve readability and avoid conflicts with on-screen elements. Each file is tested for user experience, accessibility, and compatibility with delivery platforms.

Burned-In Subtitles vs. Sidecar Files
We offer both:
- Burned-in (open) subtitles, permanently embedded in the video file—ideal for patient-facing or public communications
- Sidecar subtitle files, delivered separately for flexible playback and content reuse in multilingual formats
Region-Specific Subtitle Formatting
Subtitle styling, timing, and structure are adapted based on local readability standards and regional platform requirements (e.g., EMEA character limits, FDA submission formatting, APAC language display nuances). This ensures both technical compatibility and cultural appropriateness.
Compliance & Accessibility in Subtitle Localization
In the highly regulated life sciences industry, subtitles must meet not only linguistic and technical standards but also stringent compliance and accessibility requirements. At Sesen, we ensure all subtitle deliverables are aligned with global health authority regulations and digital accessibility frameworks to support inclusive, multilingual communication.
