Choose the access materials from the media type
Inventory the media: live or prerecorded, audio-only, video-only or synchronized media, and the meaning carried by speech, sound, images and text. W3C’s planning guidance shows why the needs differ by media type.
For prerecorded video with meaningful audio, plan captions. If important visuals are not spoken, add them to the narration or provide an audio-described version or descriptive transcript. Audio-only media needs a transcript; live media needs a captioning plan and a corrected recording before reuse.
Label languages clearly. W3C distinguishes same-language captions from translated subtitles, though regional terminology varies. A translation alone does not represent meaningful sounds in the original audio.
- Record what the viewer must understand from sound, image, movement and text.
- Separate live-event needs from the corrected on-demand version.
- List the language and purpose of each caption or subtitle track.
Build access into the brief and the script
Put companion files, languages, player and destination into the brief and estimate, with an owner for creation and review. Keep any customer or procurement standard visible and confirm its scope with the responsible owner.
In the script, flag meaning shown only on screen: a number, product label, speaker name or chart. Add a concise explanation when it fits naturally. A B2B video script template can pair spoken lines with their visual proof and reviewer.
Flag essential text in storyboards and leave safe space for captions in every crop. Plan the frame before styling the captions.
- Include caption, transcript, description and player work in scope, schedule and budget.
- Name the person who checks technical terms, names, numbers and product behaviour.
- Write or describe essential information that would otherwise be visible only in a graphic or interface.
- Plan safe space for captions in every required aspect ratio.
Make captions accurate, readable and synchronized
Treat automatic captions as a draft. Compare them with the locked audio: a missed negation, name or number can change a claim. Check speaker labels, technical terms, meaningful sounds and timing. W3C’s captions guidance explains content and accuracy checks.
Watch the complete cut with captions enabled and sound on, then muted. Confirm synchronization, readable phrase breaks and no overlap with faces, chart values, controls or qualifiers. Recheck each language track against its own export.
Use selectable captions on web players when supported. A social edit may also need open text, but keep the caption file and language metadata with the master.
- Compare words, numbers, names and speaker labels with the final audio.
- Represent meaningful sound cues, not only dialogue.
- Check synchronization, line breaks, reading time and visual obstruction.
- Label same-language captions and translated subtitles so viewers can choose correctly.
- Inspect each export after resizing, reframing or changing the edit.
Describe visual meaning and make transcripts useful
Captions do not explain visual-only meaning. Review charts, interface changes, labels and actions; add essential details to the narration or plan an audio-described version or descriptive transcript.
A transcript is more than a subtitle export. W3C transcript guidance distinguishes speech and sound from a descriptive transcript that also covers important visuals. Start with corrected captions, then add missing on-screen information, speaker names and useful headings.
Put the transcript beside the player and match it to the exact version. The B2B video SEO checklist covers the watch page and surrounding content.
- Identify visual facts that matter to the viewer’s understanding or decision.
- Use integrated narration when it fits; add separate description when it does not.
- Include meaningful visuals and on-screen words in a descriptive transcript.
- Place the transcript where a viewer can find it without hunting through the site.
Test the player and the actual publishing destination
Open the actual page or platform. Check that captions can be selected, controls work, and the transcript is close to the player. Section508.gov’s synchronized-media checklist covers U.S. federal ICT; it is not a universal legal rule.
Test each variant on desktop or phone as required. Crops can hide a chart label; open captions can sit under controls; translated text may not fit a faster cut. Check the published page without an editor login.
The video production workflow covers handoffs. Include caption, transcript and player acceptance in the delivery gate.
- Test the page on the intended device and the real player, not only in the editing software.
- Check caption controls, transcript access and clear language labels.
- Review crops, text placement and timing for each aspect ratio and language.
- Ask the applicable policy owner whether a named standard or procurement condition applies.
Assign ownership and recheck changes
Name owners for scope, captioning, technical review and destination testing. One person should confirm the package and flag unresolved requirements; a vendor label alone does not say what was checked.
Store the master with its captions, transcript, language, destination and approval date. Recheck companion files when speech, graphics or crops change; approval of one version does not cover unchecked translations.
Use the video content audit checklist to assign each library asset an action, owner and review date.
- Keep each companion file attached to the exact video version and destination.
- Recheck captions and transcripts after meaningful changes to speech, graphics or timing.
- Record checked languages, aspect ratios, devices, player and policy requirements.
- Assign an owner and date for unresolved issues instead of silently passing them forward.
Use this final release checklist
Before release, verify the viewer information, companion files, reviewer, destination controls and exact approved version. Resolve missing owners or assets before publication; accessibility is part of the delivery, not an export setting.
Add these checks to the video edit review process so the final cut is assessed in its real viewing context.
Example: a product demonstration with a chart
A software team records a narrated workflow demonstration, but a comparison chart appears without explanation. Captions cover the narration, not the chart’s categories or values. Before filming, the producer adds one concise spoken explanation. The transcript preserves that point and the product name; the publisher places it beside the video, attaches the corrected caption file and tests both with audio muted.
A social cut gets its own subtitle placement and chart crop check. The release owner records the language, ratio and destination reviewed. This illustrates a method, not a client result.
Put the idea into the room.
At kickoff, list each master and cutdown with its language, destination and access files. Flag facts shown only on screen and add them to the narration or descriptive transcript. After picture lock, correct captions against the export and test the player on the destination device. Name one owner to accept the package and recheck assets when the story or interface changes.
Check the decision before adding output.
- What meaning is carried by speech, sound, images and on-screen text?
- Can viewers get the key point with sound muted or without seeing the image?
- Who checks captions against the final export?
- Can viewers find the transcript and use caption controls on the real player?
- Who rechecks assets when the edit, language or placement changes?
Quick answers
Questions people ask about this topic.
How do you make a B2B video accessible?
Inventory the audio, visuals, language, audience and destination first. Plan accurate captions for meaningful audio, provide a transcript or visual description when needed, and test the final player and every published version.
Are captions enough to make a video accessible?
Not always. Captions communicate speech and meaningful sounds, but they do not necessarily explain important charts, actions or text shown only on screen. Decide whether narration, an audio-described version or a descriptive transcript is also needed.
Are automatic video captions accurate enough to publish?
Treat them as a draft. Check the caption file against the final audio for names, numbers, negations, technical terms, speaker labels, meaningful sounds and timing before release.
What is the difference between captions and a transcript?
Captions are synchronized with the video and represent relevant audio. A transcript presents the information in text; a descriptive transcript can also include important visual information that captions alone do not convey.
When should a video transcript be published?
When it helps people access or revisit the information, place it on the video page or link to it clearly beside the player. Keep it matched to the exact version and language it describes.
