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.

AI Video Copilot (Instant Video Q&A)
Your workflow shouldn't end with just extracting an SRT file. Version 2.9 introduces preset "AI Insight Prompts" that perfectly bundle your subtitles with actionable questions. With a single tap, send them to your favorite AI to handle heavy lifting like 【Fact-Checking】, 【Instant Summary】, 【Title Generation】, and 【Thumbnail Inspiration】.
Built-in Standard Format Video Playback
Preview Instantly: Many users struggle with how to open and play their newly translated SRT subtitles. Version 2.9 adds an integrated player supporting standard system-compatible formats (such as MP4, MOV, M4V). You can now play your video and overlay the extracted/translated subtitles directly inside the app—delivering a smooth "Extract, Translate, and Preview" experience.
【Privacy & Sandbox Security】
Zero Storage, Zero Copies: We deeply respect your data privacy. Strictly operating within the Apple Sandbox framework, the app never stores, duplicates, or caches your video files.
Temporary Access Lifecycle Management: The app requests only transient read-only permissions via system-secured tokens (Security-Scoped URLs) in memory. Once this temporary security token expires, the file is securely released. If you need to access it again, the app will safely prompt you to reconnect/re-import the file. Your media remains 100% under your control.
【Algorithm Fixes & Performance Enhancements】
4. Refined Auto-Detection Optimization (Bug Fixes)
We addressed edge cases from the previous version where certain videos with unusual aspect ratios or complex backgrounds caused hiccups in our automatic template extraction (subtitle positioning and language auto-detection). The "Zero-Configuration" pipeline is now rock-solid.
