A video is only useful if everyone can follow it. 2D closed caption descriptive video service helps people who can’t hear the audio and people who can’t see the screen.
This guide explains how it works, what US rules apply, and how to pick a provider.

What Is 2D Closed Caption Descriptive Video Service?
It combines two accessibility tools: on-screen text for sound, and spoken notes for visuals. Each one fills a gap the other can’t.
Closed captions are text that shows spoken words, speaker identification, sound effects, and music cues. Viewers can switch them on or off.
2D closed captions are standard, flat-screen captions made for regular video. Providers such as Acadecraft list them next to descriptive video. The “2D” label also separates them from captions placed in depth for 3D content. It is an industry term, not a legal one.
What is descriptive video service (DVS)? It is audio description. A narrator describes key visuals, like actions, scenes, and on-screen text, during pauses in dialogue. It helps blind and low-vision viewers.
Who needs it?
- Schools and colleges
- TV and streaming brands
- Corporate training teams
- Museums, tourism, and gaming companies
- Marketing teams and video producers
The need is large. About 15% of American adults (37.5 million) report some trouble hearing, according to the NIDCD.
A strong caption can make an accessible video even more engaging, especially when celebrating meaningful family moments. For ideas that pair perfectly with a child’s special milestone videos, explore these 1st birthday captions for cute and heartwarming Instagram posts.
Closed Captions vs. Descriptive Video Service: Key Differences
Captions turn sound into text. Descriptive video turns visuals into sound. Most accessible video needs both.
| Feature | Closed captions | Descriptive video service |
|---|---|---|
| Helps | Deaf and hard-of-hearing viewers | Blind and low-vision viewers |
| What it adds | Dialogue, sound effects, music cues | Actions, settings, on-screen text |
| Format | Text track (SRT, WebVTT, SCC) | Extra audio track or narration |
| Viewer control | On/off with a CC button | Chosen as an audio option |
What are the main caption styles?
- Pop-on: Text appears in blocks. It is common in TV and film.
- Roll-up: Text scrolls up. It is now rare in pre-recorded video.
- Center placement: One or two lines at bottom center. It is common online.
Human, AI, or hybrid captions? AI is fast and cheap. It can miss accents, names, and technical terms. Human review catches those errors. Hybrid captions pair human transcripts with AI timing, as Word Wizards offers.
Captions also help video SEO. Search engines can read a transcript, and viewers can watch with the sound off.
US Rules for Closed Captioning and Descriptive Video Service
Several US rules cover captions and descriptions. Which one applies depends on who you are and where the video airs.
What does the FCC require? For TV, the FCC sets four caption quality rules: accuracy, synchronicity, completeness, and placement. Captions must match speech and run start to finish. They must not block key visuals.
What about audio description on TV? Local ABC, CBS, Fox, and NBC affiliates in covered markets must air 87.5 hours of described programming per quarter. As of January 1, 2026, the rule reaches the top 120 markets. The FCC adds 10 more markets each year through 2035.
What does the ADA require? In 2024, the DOJ named WCAG 2.1 Level AA as the standard for state and local government web content. That includes captions for live and pre-recorded video. In April 2026, the DOJ extended the compliance dates by one year, to April 26, 2027, for the first group. Private businesses face separate duties under Title III. Check with a lawyer for your case.
What do Section 508 and WCAG say? Section 508 covers federal agencies. WCAG asks for captions on pre-recorded video (1.2.2) and audio description (1.2.5 at Level AA).
Quick quality checklist:
- Keep lines short, about 32 characters or less
- Show one to three lines for 3 to 6 seconds
- Name speakers when they’re off-screen
- Add cues like [music] and [laughter]
- Spell terms and names correctly
