SubTrans

Create, translate, edit, and export video subtitles in one workflow.
This app is designed for video creators, editors, students, language learners, and anyone who needs a practical way to add subtitles to videos. You can use locally deployed models to recognize speech and translate subtitles, or use OCR to detect existing on-screen subtitles and translate them into another language.
Whether you are adding captions to your own videos, translating videos without subtitles, or preparing subtitle files for editing and publishing, the app helps you manage the process from recognition to final export.
Key features:
Local speech recognition and translation
Use locally deployed models to process video audio and generate subtitles. This is useful when you want more control over your workflow and prefer not to rely entirely on online subtitle services.
OCR subtitle recognition
For videos that already contain on-screen subtitles, OCR can help extract the text so you can translate, correct, and reuse it.
Subtitle editing and correction
Edit recognized text, adjust subtitle timing, refine translations, and correct segmentation before exporting. This makes it easier to prepare subtitles that match the pace and meaning of the video.
Export video or SRT
Export a video with subtitles embedded, or save subtitles as an SRT file for use in video editors, media players, or other production tools.
Useful for:
Adding subtitles to personal videos, vlogs, tutorials, and courses
Translating videos without subtitles
Extracting and translating existing on-screen subtitles
Creating bilingual subtitles
Exporting SRT files for editing, publishing, or archiving
From subtitle recognition to translation, editing, and export, the app brings the main subtitle workflow into one place so you can create captions with more control and less switching between tools.
