Script-based captions and their limits

Identify where the caption text comes from

Captions can use a prepared script or recognized speech. The first approach already has the words and needs to place them in time. The second first determines what was said. Their errors differ. Current Takt captions use the script and reading timeline rather than a microphone transcript.

They can be useful when delivery closely follows the text. If you skip phrases, change their order, or add explanations, the captions may diverge from the audio. Do not present them as a verbatim transcript without reviewing them. Check numbers, names, and wording that changes the meaning especially carefully.

Choose the workflow

This is a workflow choice, not a claim that one method is always more accurate. Recognized text still needs proofreading. A correctly written script can still be mistimed against a particular take. Review both the words and their appearance times rather than treating either as automatic evidence of the other.

Check synchronization

Enable captions before a trial. Read a short paragraph, pause, and continue. Download the file and compare the opening, the return after the pause, and the ending. If you deliberately replaced a word, inspect what remained on screen. This makes the difference between script text and spoken content visible.

Do not review only the start. Small departures can become more noticeable later. For a prepared clip, rerecording a short block may be easier than retaining incorrect captions. For a freely delivered presentation, preserve a clean video and prepare captions after filming instead of expecting a script timeline to track improvisation.

Readability comes before decoration

Check the text against light and dark areas, a longer phrase, the bottom of a slide, and the circular camera. If captions hide an important object, viewers have to choose between reading and following the demonstration. Adjust the material or the captioning workflow rather than assuming the overlay is harmless.

Watch the sample on a small screen. A size that looks comfortable on a laptop may be too small on a phone. Do not judge only a still frame: the audience needs enough time to read the line. Avoid removing essential meaning just to fit an attractive-looking caption style.

Understand burned-in captions

In this release, captions are drawn into the output frame. They are not a separate track viewers can necessarily disable. Removing them later is harder than changing a subtitle file. A clean source is particularly useful for future translations, revisions, and editing.

Are these captions sufficient for accessibility?

They can help, but verify their agreement with the complete recording. Text at the bottom alone does not establish accessibility. Accuracy, timing, readability, and descriptions of meaningful sounds may all matter. Review the actual result rather than making a broad claim based on the presence of an overlay.
