SRTWhisper

SRTWhisper is a software solution for creating multilingual subtitles for videos. It uses Whisper AI speech recognition and LLM-powered translation for transcribing, translating, editing, exporting, and burning-in subtitles.

Key features include Speech Transcription, Multiple Translation Engines, a Subtitle Editor with Live Preview, a Quality Checker, and Flexible Export options. For transcription, it uses WhisperKit with seven model sizes for speed and accuracy balance, automatic language detection, and manual source language selection. The translation engines include local LLM, OpenAI GPT models, Ollama local server, and a custom OpenAI-compatible API endpoint.

The Subtitle Editor allows users to edit text and timing, add, delete, merge, or split segments, and adjust start/end times. The Quality Checker identifies common issues like overlapping timestamps, high reading speed, and long lines and offers one-tap fixes. Users can export as SRT, WebVTT, or ASS/SSA, or burn subtitles into the video with customizable font, size, color, outline, and position.

SRTWhisper is suitable for video creators needing multilingual subtitles, professionals transcribing interviews, lectures, or meetings, and anyone preferring local processing over cloud data storage.
