Video captions are timed text that represents spoken dialogue and, where relevant, other meaningful audio. They help viewers follow speech in noise, watch with the sound off, and reread the name or number they just missed. They can be burned into the video or delivered as a separate selectable track, and that one choice shapes half the workflow.
The principle for this whole series: captions should make the video easier to understand without becoming a second competing performance. Accuracy comes before styling, grouping comes before animation, and the review happens on the exported file, because a caption that only looks right inside the editor is not right yet.
One warning that pays for itself: automatic transcription is a useful first draft, and names, numbers, specialist terms, punctuation, timing and line breaks still deserve a human pass. Correct wording that reads "the result did increase" when the speaker said "did not" is a spelling-perfect error, which is exactly the kind captions specialise in.
The seven guides below run the full arc: the terminology, the step-by-step workflow, animation, styles, readability, the pre-export review, and how captioning fits inside the complete edit.
