How does an AI caption generator work?
An AI caption generator turns spoken audio into timed text on a video. Moralab transcribes uploaded footage when captions are enabled. For narration generated from a script, it uses voice timing to build the captions. You can choose a preset or customize the appearance before exporting the captioned video.
Make the details
yours.
Use sentence, word-by-word, or one-word reveals to match the pace of the speech.
Use size, border, shadow, and positioning to keep the captions legible without covering the subject.
Keep captions with the video project, so you can review them alongside visuals, narration, and music.
Make every word count.
