Subtitles, Closed Captions & SDH — What’s the Difference?
Subtitles, closed captions, and SDH subtitles are three distinct formats that serve different audiences and purposes — and understanding the difference is critical for meeting platform delivery requirements and accessibility compliance obligations.
Subtitles
Subtitles are text displays of spoken dialogue translated into a target language, intended for viewers who can hear the audio but do not speak the source language. They translate only the spoken words — they do not describe sound effects, music, or ambient audio. Subtitles are the primary format for international distribution and foreign-language releases.
Closed captions
Closed captions are a text representation of all audio content in a video — including spoken dialogue, speaker identification, sound effects, music descriptions, and silence notations. They are intended primarily for viewers who are deaf or hard of hearing and who are watching content in their own language. FCC regulations require closed captions on broadcast television content. Major streaming platforms including Netflix, Amazon, and Disney+ require closed captions on all English-language content as a condition of delivery.
SDH subtitles — Subtitles for the Deaf and Hard of Hearing
SDH subtitles combine the translation function of subtitles with the accessibility features of closed captions — providing a translated text of the dialogue alongside speaker identification, sound effect descriptions, and music cues. SDH is the required format for foreign-language accessibility compliance on streaming platforms. Netflix, Amazon Prime Video, and Disney+ all require SDH tracks in addition to standard subtitle tracks for international content packages.
Gotham Lab provides all three formats — standard subtitles, closed captions, and SDH subtitles — delivered in every required file format for every distribution channel.

Streaming Platform Subtitle Delivery
Each major streaming platform has specific technical requirements for subtitle and closed caption file delivery. Non-compliant files trigger delivery rejections that delay your release and require costly rework. Gotham Lab’s subtitling team is familiar with the current technical specifications of every major platform and delivers files that pass quality control on the first submission.
Netflix subtitle requirements
Netflix requires subtitle files in TTML/DFXP format for all foreign-language content and English SDH tracks for all content. Netflix has specific requirements for font, position, reading speed (17 characters per second maximum), line breaks, italics usage, and timecode precision. All Netflix subtitle deliveries must be accompanied by a CCSL spotting list for series and feature content. Gotham Lab delivers Netflix-compliant subtitle packages including the required DFXP files, SDH tracks, and CCSL documentation.
Accessibility & Compliance — FCC, ADA & WCAG
Closed captioning and SDH subtitles are not optional for many content types — they are legally required. Understanding which regulations apply to your content is critical for compliance and for avoiding penalties.
FCC closed captioning requirements
The Federal Communications Commission (FCC) requires closed captions on all television programming in the United States, including content that was originally broadcast with captions and is later distributed online. Video programming distributors and providers must comply with FCC caption quality standards covering accuracy, synchronicity, completeness, and placement. Gotham Lab provides FCC-compliant closed captioning in SCC and all required broadcast formats.
ADA and
Section 508 compliance
The Americans with Disabilities Act (ADA) and Section 508 of the Rehabilitation Act require federal agencies and organizations receiving federal funding to ensure that multimedia content is accessible to people with disabilities. For video content, this means providing accurate closed captions and — where applicable — audio description. Gotham Lab provides ADA and Section 508-compliant captioning services and works with organizations to audit and remediate existing caption files for compliance.
WCAG 2.1 web accessibility guidelines
The Web Content Accessibility Guidelines (WCAG) 2.1 require captions for all pre-recorded audio content in synchronized media at the AA compliance level. For organizations publishing video on websites, intranets, or digital platforms, WCAG compliance requires accurate, synchronized closed captions. Gotham Lab provides WCAG-compliant caption files in all web-compatible formats including VTT and SRT.
* For organizations requiring full multimedia accessibility compliance including both captioning and audio description, Gotham Lab’s audio description services team provides end-to-end accessibility solutions meeting all current US and international standards.
