How to make interactive training videos accessible and effective

Who needs accessible training video

In the United States, employers must provide reasonable accommodations so that employees with disabilities can take part in employer-sponsored training, unless that causes undue hardship (EEOC guidance on the ADA, question 15). Federal agencies must make educational and training materials conform to WCAG 2.0 Level A and AA under the Revised Section 508 Standards, provision E205.3 (U.S. Access Board).

State and local governments must make the web content they provide meet WCAG 2.1 Level AA under the Department of Justice's ADA Title II rule. An interim final rule published on April 20, 2026 moved the compliance dates to April 26, 2027 for entities that serve 50,000 or more people, and to April 26, 2028 for smaller entities and special districts (ADA.gov, checked October 2026). Outside the US, check the rules where your learners work.

Accessible video also helps learners without a disability. In a 2015 review, Morton Ann Gernsbacher of the University of Wisconsin–Madison summarized more than 100 studies that found captions improve comprehension of, attention to, and memory for video. Captions help most for viewers who watch in a second language, people learning to read, and viewers who are deaf or hard of hearing (Policy Insights from the Behavioral and Brain Sciences, 2015).

What WCAG 2.2 asks of an interactive video

WCAG 2.2 is the current version of the W3C's Web Content Accessibility Guidelines. Level A is the minimum. Most laws and policies point to Level AA, which includes every Level A criterion. These are the criteria that most often decide whether an interactive training video works for every learner.

WCAG 2.2 success criteria for interactive training video, and what to do in Mindstamp (checked October 2026)

Requirement	WCAG 2.2 criterion	What to do in Mindstamp
Captions for all speech	1.2.2 Captions (Prerecorded), Level A	Upload a VTT or SRT file on the Captions page, or create a transcript to get an English caption track. Correct names and numbers by hand.
Information that only the screen shows	1.2.3 Audio Description or Media Alternative, Level A; 1.2.5 Audio Description (Prerecorded), Level AA	Describe on-screen steps in the narration when you write the script. The transcript Mindstamp creates from that narration then includes the descriptions.
Every interaction works from a keyboard	2.1.1 Keyboard, Level A; 2.4.7 Focus Visible, Level AA	Buttons are real buttons, and learners can reach hotspots with the Tab key. Test each video with only Tab, Enter, and Space.
Each control has a name a screen reader can announce	1.1.1 Non-text Content and 4.1.2 Name, Role, Value, Level A	Give each image and hotspot a caption. Mindstamp uses it as the text a screen reader announces.
Enough time to read and answer	2.2.1 Timing Adjustable, Level A	Leave Time Limit off on questions. Keep the pause control unless the training cannot work without removing it.
Meaning that does not depend on color	1.4.1 Use of Color, Level A	Show the result of an answer in words, such as the Try Again prompt or a message that explains the answer.
Readable text and controls	1.4.3 Contrast (Minimum), 4.5:1 for normal text; 1.4.11 Non-text Contrast, 3:1 for controls; both Level AA	Give buttons and text a solid background color instead of placing light text over moving video.
Targets large enough to tap	2.5.8 Target Size (Minimum), at least 24 by 24 CSS pixels, Level AA	Size buttons for a phone, where the video is much smaller than in the editor, and test on one.
No sound that starts by itself	1.4.2 Audio Control, Level A	Mindstamp's autoplay option starts the video muted.

Our free video accessibility checker walks through the WCAG criteria for a published video and checks a caption file. The caption validator finds overlapping and hard-to-read cues and repairs the safe ones.

How to build an accessible interactive training video in Mindstamp

1. Write the script for learners who cannot see or hear it

Say what the screen shows: "Select Save at the top right" works for every learner, and "click here" does not. Read on-screen text aloud, and avoid questions that depend on color. Drawing, video, and voice response questions need a mouse or touch screen, a camera, or a microphone, so offer another way to answer, such as a free response question.

2. Add captions and a transcript

Open the video and select Transcript, then Create Transcript. Processing usually takes about half the length of the video. Edit the transcript to fix names and terms, and save it. Mindstamp then updates the English caption track. If you already have caption files, upload a VTT or SRT file for each language on the Captions page instead, and select Make default on a track that should be on when the video starts. Save caption files as UTF-8 so accented letters show correctly. Transcripts work for uploaded videos and MP4 links, not for YouTube or HLS links. The help articles on closed captions and video transcripts cover the details, and the transcript to captions converter turns a plain script into a timed caption file.

3. Give every interaction a name and a clear look

Give each image and hotspot a caption that says what it is or does. Write button labels as actions, such as "Open the lockout procedure". Use a solid background behind button text, and make buttons large enough to tap on a phone. Check the device setting on each interaction: Desktop Only hides it on phones, so a learner on a phone never sees it.

4. Set questions so every learner can answer

A question pauses the video until the learner answers, which gives every learner time to read. These settings keep it that way:

• Leave Time Limit off. When it is on, the question closes after 2 to 90 seconds, whether or not the learner has finished reading.
• Turn on Speak Question and Speak Answers to read the question and its answers aloud in one of 13 generated voices. Mindstamp creates the audio when you save the question, so every learner hears the same voice.
• Add a hint, and use Repeat Until Correct so a learner who answers wrong sees Try Again and answers again. Repeat Until Correct needs Show Correctness on, no time limit, and skipping off.

The help article on adding questions lists every question setting.

5. Keep the controls learners need

Do not turn on Hide All Controls unless the video gives learners another way to pause and move on. Use Prevent pausing only when the training cannot work without it, because learners who need more time cannot stop the video. Keep Show Speed on, so learners can change the playback speed. To stop learners from skipping required content, turn off Allow Seeking or, on supported plans, turn on Prevent passing required interactions. Both keep the pause button. See how to set player controls.

6. Translate for learners who work in another language

On the Translate page, Interactions only translates buttons, questions, forms, hotspots, text, and player text and keeps the original audio. Full audio dub also adds translated audio, captions, and a transcript in each language (dubbing costs). A dubbed track keeps only the new voice, so the original music and sound effects are lost. The player uses the learner's browser language when a translation exists, and learners can change the language in the player. Review machine translation before you share safety or compliance training. See how to translate an interactive video.

7. Test before you share

Open the share link in a private browser window, because owners and editors see skip controls that learners do not. Then:

1. Play the whole video using only a keyboard. You should reach and use every button, hotspot, and question.
2. Play it with a screen reader and check that each control has a clear name.
3. Play it on a phone in portrait and in landscape, with captions on, and check that the captions stay readable over your interactions.
4. Run the video accessibility checker and keep the report with the training record.

The help article on checking a video on a phone has a full phone test, and the accessibility features article lists what the player supports.

What makes interactive training effective

Spread the questions through the video. In a 2013 Harvard study, students watched a 21-minute statistics lecture in four segments. Students who took a short test after each segment reported mind wandering in 19% of checks, against 39% and 41% in the two groups without tests, and scored 90% on the final test, against 76% and 68% (PNAS, 2013). In the interview clip below, Brett Lindenberg says that when Mindstamp customers compare the same video with questions spread through it and with one quiz at the end, the spread version gets much higher correctness and participation. Brett is describing customer reports, which do not control for other differences between videos. The Harvard experiment above is the controlled evidence.

An eLearning Industry article by Neil Glenister (2020, updated 2021) argues that effective training combines play, a growth mindset, and learning that people direct themselves. In an interactive training video, four design choices do most of the work:

• Ask one question right after each key idea, before the next idea starts.
• Explain why each answer is right or wrong, and give a wrong answer a way back: Repeat Until Correct, or a Change Time action that replays the explanation.
• Turn judgment calls into a branching scenario, where the learner picks an action and sees what happens.
• After the first group finishes, open the Questions report and rewrite the section before the most-missed question.

Our guide to assessing learning with interactive video covers question writing and placement in depth.

Accessible to build on a small budget

For years, high-end interactive training was expensive, hard to produce, and soon out of date, as Brett Lindenberg says in the clip below. Today you can record a lesson on a phone or an inexpensive camera, upload it or link it from Vimeo, Wistia, JW Player, or Kaltura, and add questions, buttons, hotspots, and branching on top of it. When a step changes, Replace source video swaps the footage and keeps the interactions, the share link, and the embed code. For the costs to plan for and when the investment pays back, read the benefits of investing in interactive video for training.

Brett Lindenberg on accessible, effective training

Mindstamp's founder, Brett Lindenberg, discussed the future of training with Karla Roberts, Instructional Designer at Motive Learning, which makes video-based compliance training, on Jon Skattum's interview series jonTalk. In this 57-second clip, Brett explains why interactive training no longer needs a large budget and how Mindstamp reports show whether it works.

Common questions

Is Mindstamp WCAG compliant?

Mindstamp does not publish a WCAG conformance level or a VPAT. The player and its interactions support captions, keyboard operation, and screen reader labels, and questions can be read aloud. Whether a finished video meets WCAG also depends on your choices, such as caption accuracy and time limits, so test each video. If your procurement team needs a statement, contact Mindstamp with your requirements.

Are captions and a transcript the same thing?

No. Captions show the words on the video as it plays. A transcript is the full text beside the player, which learners can read, search, and use to jump to a moment. WCAG treats them as separate requirements. Mindstamp makes an English caption track from the transcript, and you can upload caption files for other languages.

Can learners who use a screen reader answer questions?

Player controls, question text, and forms use ARIA roles and labels, and buttons are real buttons, so screen readers can reach and announce them. Test each question type with the screen reader your learners use, and offer a text answer in place of drawing or recorded responses.

Do accessible training videos work on phones?

Yes. Use the responsive embed code, and test every interaction on a phone in portrait and landscape. Learners turn captions on with the player's captions control. Avoid the Desktop Only device setting on any interaction a learner needs.
