Camtasia
Camtasia is a screen recording and video editing suite that also offers captioning features. After recording tutorials, demos, or presentations, users can add captions through a built-in editor. The speech-to-text feature (on some OS versions) auto-generates a rough transcript, which can be refined or replaced. Captions are easily styled, timed, and exported with the final video. Camtasia also supports callouts, annotations, and transitions, making it popular among educators, trainers, and marketers who want to produce professional screencasts with accessible captions built in.
