What Is an AI Video Translator?
An AI video translator automatically converts video content from one language to another by transcribing speech, translating text, and generating subtitles or dubbed audio in your target language. This ai powered translation happens in minutes instead of days required for traditional human translation.
The process involves three steps:
1. Transcription: AI converts speech to text
2. Translation: Neural networks translate while preserving context
3. Output: Creates subtitles, dubbed audio, or both
Modern AI video translators support 80-130+ languages and process videos up to 4K resolution.
