AI Video Translator — Translate Videos to 100+ Languages Automatically (2026)
AI Video Translator — Translate Any Video to 100+ Languages
AI can now translate videos in minutes, not days. Here's how the technology works and how to use it.
What Is an AI Video Translator?
An AI video translator is software that automatically:
- Transcribes the audio (speech-to-text using AI like Whisper)
- Translates the text into your target language (using LLMs like Gemini)
- Generates subtitles with proper timing
- Burns subtitles into the video (optional)
The entire process takes 5-15 minutes for a typical video, compared to hours or days with human translators.
How Subly's AI Translation Works
Step 1: Audio Extraction
The video's audio track is extracted and converted to a format optimized for speech recognition.
Step 2: AI Transcription (Whisper)
OpenAI's Whisper model transcribes the speech. Whisper handles: - 99 languages as input - Background noise and music - Multiple speakers - Accented speech - Fast speech patterns
Step 3: AI Translation (Google Gemini)
The transcribed text is translated using Google Gemini AI, which: - Understands conversational context (not just word-by-word) - Preserves tone and register (formal vs. casual) - Handles idioms and cultural references - Maintains speaker consistency throughout the video
Step 4: Subtitle Generation
Translated text is split into properly-timed subtitle segments that match the original speech timing.
Step 5: Video Rendering
Subtitles are burned into the video with readable formatting (white text, dark background, proper font size).

FAQ
How accurate is AI video translation?
For conversational content (dramas, vlogs, tutorials), AI translation is 85-95% accurate. The technology handles context, idioms, and multi-speaker conversations well. It may struggle with heavy slang, regional dialects, or highly technical terminology.
Does it translate the audio or just existing subtitles?
It transcribes the actual audio. Even if the video has no subtitles, Subly extracts the speech, converts it to text, translates it, and generates new subtitles.
Can AI translate videos in real-time?
Not yet. Current AI video translation takes 5-15 minutes of processing per video. Real-time translation is possible for short segments but not practical for full videos at high quality.
What's the maximum video length?
The free trial covers 30 minutes of video. Paid plans support videos up to 2 hours.
