How to Translate a Video: Subtitles, Voiceover, and Dubbing
Video translation encompasses three distinct approaches: subtitles, voiceover, and dubbing. Each approach requires different tools, budgets, and technical expertise, and serves different audience preferences and accessibility requirements.
For subtitles, the most cost-effective workflow combines transcription tools (like Otter.ai or Whisper) with translation (DeepL API or Google Translate API) and subtitle formatting software (Subtitle Edit, Aegisub, or Descript). Automated subtitle translation services like Wordly provide real-time captioning for live videos and webinars, supporting 30+ languages with low latency. Subtitle timing is critical: each subtitle should be displayed long enough to read comfortably while staying synchronized with the audio.
Voiceover and dubbing require more investment. AI voice cloning technologies have improved dramatically in 2026, with tools like ElevenLabs and Respeecher offering multilingual voice synthesis that preserves the original speaker's voice characteristics. However, AI dubbing still lacks the emotional range and nuanced performance of human voice actors for premium content like films, advertisements, and narrative videos. For professional video localization, the recommended approach is AI-generated subtitles for accessibility and draft translation, with human-created voiceover or dubbing for published content.
