Portable Snap Video Translator 1.1.1 (Models Included)
Snap Video Translator Portable brings every step of localizing a video into a single Windows app. Load a video and it takes you straight through transcription, AI translation, and either subtitle burn-in or an AI voice-over.
Transcription (runs locally)
Runs OpenAI Whisper on your own PC. Choose from small / medium / large-v3-turbo / large-v3 to balance speed and accuracy. Your audio is never sent to an external server for transcription.
AI translation
Works with AI services such as Gemini, OpenAI, and Claude, or with an OpenAI-compatible local LLM. Produces natural translations of your video’s content.
Subtitle burn-in
Adjust font size, text color, outline, and position, then burn subtitles directly into the video.
AI dubbing
Converts the translation into speech and generates a voice-over in 7 languages (Japanese, English, Chinese, Korean, French, German, Spanish). Mix it with the original audio or replace it.
Subtitle file export
Export subtitle files in SRT / VTT format.
Review & edit mode
Check the subtitle text on screen before burn-in and edit it if needed.
Batch processing
Process multiple videos at once.
Who it’s for
– Video creators who want to reach viewers in other languages
– Education and training teams localizing lectures and tutorials
– Companies localizing internal videos
Before you start
– Transcription runs locally with Whisper; your audio is not sent anywhere.
– Using a cloud AI service for translation requires that service’s API key. You can also use an OpenAI-compatible local LLM.
– AI translation and AI dubbing require an internet connection (no API key is needed for dubbing).
– Subtitles and dubbed audio are AI-generated. Please review the output before public or business use.
– FFmpeg is bundled as the video processing engine.
