SubVision

Key Features

SubVision is a professional macOS tool designed to extract hardcoded (burned-in) subtitles from video files.

Powered by Apple’s Vision framework, SubVision analyzes your video frame by frame to detect on-screen text and convert it into accurate, time-coded SRT files.

You can then review, fix, and refine the results directly on the timeline — or create subtitles manually when needed.

The output is a standard SRT file, fully compatible with major professional editing systems including Adobe Premiere Pro, DaVinci Resolve, and Final Cut Pro.

Intelligent Import & Guided Workflow

SubVision is designed to get you from video to subtitles in seconds.

A guided three-step workflow ensures accurate results from the very first scan:

• Import your video — drag & drop or open it from your system
• Define the subtitle area — focus only on what matters
• Start scanning — and let SubVision do the rest

Built-in playback controls and frame-accurate navigation give you full control during every step of the process.

Precision ROI (Region of Interest)

Focus only on the subtitle area to maximize accuracy and speed.

By restricting the scan to a specific region, SubVision ignores logos, watermarks, and background elements that can interfere with OCR.

• Visual overlay — define exactly where text is detected
• Resizable area — adapt to any subtitle layout
• One-click reset — instantly return to full frame

Multi-Level Scanning Modes

From full automation to surgical correction — SubVision adapts to your workflow.

• Standard Scan — analyze the entire video or a selected range
• Rescan Range — update a specific segment without affecting the rest
• Re-read Selection — reprocess a single subtitle with precision

This layered approach lets you move from automatic detection to precise correction without restarting your workflow.

Language Recognition & Script Modes

Adapt SubVision to any language or writing system.

To reduce noise and improve accuracy, you can prioritize specific alphabets and scripts based on your source material:

• Latin / Western (Default) — optimized for English, Italian, French, German, Spanish, and other European languages
• Cyrillic — tuned for Russian and Ukrainian
• Asian (CJK) — designed for Chinese, Japanese, and Korean characters
• Arabic — dedicated support for Arabic script
• Universal (Auto) — automatic detection for mixed or unknown languages

Choose a specific script for maximum accuracy, or use automatic detection for flexible workflows.

OCR Tuning & Visual Enhancements

Handle difficult footage with precision.

SubVision gives you full control over how subtitles are detected, allowing you to adapt to low contrast, motion blur, or complex backgrounds:

• Detection presets — choose between Standard, Precision, or Hardcore modes
• Advanced tuning — adjust sample rate, confidence, and confirmation thresholds
• Visual filters — apply grayscale, contrast boost, sharpen, invert, and thresholding to enhance readability

These tools help you reduce noise, eliminate false positives, and recover subtitles that would otherwise be missed.

Professional Subtitle Editing

Review, fix, and refine subtitles directly on the timeline.

• Inline editing — update subtitle text instantly from the sidebar
• Precise timing — use Subtitle In / Subtitle Out to align subtitles frame-accurately
• Global offset — shift the entire timeline at export to fix sync issues in one step

Make adjustments in real time — without leaving the app or restarting the workflow.

Diagnostic Tool & Privacy
