Guide to captioning German short video clips locally with Whisper and FFmpeg

English caption line limits do not work well for German, where long compounds like Krankenversicherung often overflow the safe area or break awkwardly mid-word. The author recommends Whisper's medium model for German, since smaller models drop word endings, split compounds oddly, and invent names when unsure. Captioning should happen after the clip is cut and formatted to 9:16, so word timestamps match the published file and the subtitle layout matches the frame. An initial_prompt containing correctly spelled names and rare terms helps accuracy, and the language should be set explicitly rather than auto-detected. The same line-wrapping approach, with lines capped around 16 to 18 characters, applies to Dutch, Finnish, and Turkish.
