SmartSub
SmartSub is a cross-platform desktop application for AI-driven video transcription and subtitle generation. It converts audio and video files into text subtitles using local AI models and incorporates hardware acceleration to increase processing speed.
The tool features a subtitle translator that leverages large language models, such as OpenAI and DeepSeek, to convert subtitles between different languages. It includes a visual editor for proofreading and polishing transcribed text, paired with a video preview for frame-accurate synchronization.
The software supports batch processing of multiple media files and provides utilities for embedding subtitles as switchable soft tracks or permanently burning them into video frames. It also includes systems for managing transcription model files and configuring external AI service parameters.
Features
