What's New in OCR Subtitle Ultra

3.1

July 28, 2026

1. New Whisper Voice Recognition Mode Integrated the Whisper speech-to-text framework. When videos lack on-screen text or have highly cluttered backgrounds, users can select this mode to directly transcribe audio tracks into time-coded standard SRT files. Supports automatic audio language detection. 2. Refactored Functional Modes (Four Independent Options) To better accommodate varied post-production workflows, core features are now structured into four distinct, mutually exclusive modes: Manual ROI Mode: Users manually define the Region of Interest (ROI) for targeted visual OCR scanning. Auto ROI Mode: The system automatically detects and locks the subtitle area for visual OCR scanning. Voice Recognition Mode: A new mode that bypasses visual scanning entirely, performing voice-to-text transcription directly on the audio stream. Playback Only Mode: A new mode that invokes neither OCR nor voice recognition engines. It functions strictly as a standard video player, allowing users to preview media or overlay existing subtitle tracks. 3. Core Workflow Integration Subtitles generated via either OCR scanning or the new voice recognition mode integrate seamlessly with the pre-existing Seamless AI Translation Workflow and AI Video Copilot prompt templates. 4. Sandbox Privacy & Performance Optimization Strictly operates within the Apple Sandbox framework. Both audio and video streams are processed on-the-fly inside active memory with zero local copying, caching, or remote server exposure. Optimized dynamic memory release logic to improve stability when handling long-duration footage.

Fantastic App with One Suggestion

I'm very satisfied with both the OCR accuracy and processing speed. I've tried several OCR applications, and this one stands out for its excellent recognition accuracy and fast performance, which has significantly improved my workflow.

One feature I would love to see is a job queue. Currently, the app can process only one video at a time. It would be much more convenient if multiple videos could be added to a job queue and processed automatically one after another. It would also be great if each queued job could use its own template, allowing videos that require different templates to be queued together and processed automatically in sequence.

With this feature, I believe the app would be close to perfect. I look forward to seeing this app continue to improve with future updates. Thank you for creating such a great application!

“性能不错,但双行字幕存在致命问题” "Good performance, but critical issue with two-line subtitles"

性能不错,但在双行字幕中无法指定提取哪一行。它只能识别其中一行,这是一个致命的问题。请允许用户手动指定要提取的字幕范围,而不是仅依赖自动检测。


The performance is good, but it doesn't allow you to specify which line to extract in two-line subtitles. It only recognizes one of the two lines, which is a critical flaw. Please allow users to manually specify the subtitle range instead of relying solely on automatic detection.
