The short answer
Review accurate speech captions, meaningful non-speech sound, important visual information, readable text and the player’s caption options. Burned-in text and selectable caption tracks serve different functions. Use platform features where appropriate and inspect the published result. This is a production checklist, not a certification that a video or account meets every accessibility or legal requirement.
Review the meaning through different access paths
Use the same accepted script and export for these checks.
Without sound
Can the viewer understand speech and any meaningful audio event?
Without relying on the image
Does the narration or another accessible description explain the important visible action?
At the intended display size
Can the text be read without covering the subject or disappearing into the background?
In the publishing player
Are the available caption and description options accurate and usable?
Capture meaning rather than speech alone
Some sounds explain why a person reacts.
A doorbell, alarm, laugh or music change can affect the interpretation of a clip. Include meaningful sound information in the relevant caption treatment where it helps the viewer. Do not fill the screen with labels for every incidental noise. Review which sounds matter to the story or product action.
Check the transcript against the recording and correct names, punctuation and words that change the claim. Automatic transcription provides a draft, not a completed review. The caption guide covers production decisions; this checklist adds the information that a stylish speech overlay may omit.
Describe visual information when it carries the answer
A silent interface change can be the whole demonstration.
For a fictional calendar demo, the confirmation state may be visible but unspoken. A viewer who cannot rely on that image needs a way to understand what changed. Review whether the narration can naturally explain the action or whether another description is needed. Avoid redundant description of an image that contributes nothing important.
W3C’s media accessibility guidance discusses alternatives for audio and visual information. Use it as a source for planning, then review the actual format and player you will use. Do not describe a generated illustration as recorded proof or assume a general accessibility checklist resolves every audience requirement.
Distinguish embedded captions from a text track
The two treatments can coexist.
Burned-in captions are part of the picture. A selectable text track gives the player caption information it can expose and, where supported, let viewers control. Platform support and publishing routes differ. Check the account’s actual player and caption settings instead of inferring them from an editor preview.
YouTube documents caption and subtitle tools separately from on-screen graphics. Review the published track for text and timing errors. This article does not claim that Prolifik exports a selectable subtitle file in every workflow. Use its reviewed captioned clip as one production input and add or correct the platform track where the destination supports it.
Test contrast, movement and reading time
Read the difficult frame, not only the clean first image.
Use the actual caption on the busiest background, at the smallest intended display size. Inspect long words, accents, punctuation and line breaks. Leave the important subject visible. A backdrop can improve contrast, but a large block that covers the demonstration may remove the information the viewer needed.
Check fast cuts, flashing effects and moving text for avoidable barriers. Give viewers enough time to read the message before it disappears. No single font size guarantees readable video on every screen. Record the actual export dimensions and the review conditions so another editor can reproduce the check.
Assign an accessibility review with the normal approval
The checklist needs an owner and a correction path.
Record the issue, affected timecode, required change and reviewer. Review the corrected export rather than only a note that the editor changed it. Where possible, get feedback from people with the access needs relevant to the audience. Keep that input separate from a claim of universal compliance.
The AI Clipper workflow can create captioned short clips for review. Check the captions, visual context and publishing player before approval. A production tool can reduce assembly work while the team remains responsible for meaning, audience access and the final published version.
Create a clip and review every caption
Use the AI Clipper workflow, then check meaning and the destination player before publishing.
