OCR Subtitle: Video-to-SRT Extraction Tool
OCR Subtitle is a practical utility designed to extract hard-coded subtitles from videos using Optical Character Recognition (OCR). It automatically converts on-screen text into standard SRT files, saving hours of manual transcription for editors, educators, and content creators.
(Note: Recognition accuracy is subject to video resolution, font styles, and background contrast.)
Key Features
Automated Subtitle Detection: Recognizes on-screen text and generates time-coded SRT files with sequential numbering.
New in v2.5: High-Performance Engine: Built with an optimized FFmpeg backend, now supporting H.265 (HEVC), AV1, and various professional formats with significantly improved stability.
Enhanced 4K & Long Video Support: Re-engineered memory management ensures stable processing for 4K Ultra-HD footage and long-duration videos without system crashes.
Smart Region of Interest (ROI): Features a customizable scanning area with a real-time zoom preview, ensuring the OCR engine focuses precisely on the subtitle area to minimize interference.
Multilingual Recognition: Optimized for English, Traditional/Simplified Chinese, Japanese, Korean, Russian, French, and more.
Seamless Workflow Integration: Exported SRT files are fully editable and compatible with YouTube, VLC, Final Cut Pro, Adobe Premiere, and other major editing platforms.
Customizable OCR Templates: Fine-tune detection by adjusting font colors, background contrast, and recognition intervals to match different video styles.
Ideal For
Legacy Video Recovery: Reclaiming subtitle data from old videos where original project files are no longer available.
Global Localization: Rapidly creating translated versions for videos with hard-coded captions.
Content Accessibility: Converting "burnt-in" text into searchable and accessible formats.
