SubtitleYC v0.5.0

SubtitleYC is a free and open-source Windows app for extracting, reviewing,
and editing frame-timed subtitles from video.

SubtitleYC is distributed under the MIT License. Bundled third-party tools
retain their own licences, which are included with the installation.

Changes

  • Added bold, italic, underline, and color styling for selected subtitle text or whole cues.
  • Safe styled-subtitle rendering in both browser and native desktop previews.
  • Editor shortcut tooltips for formatting, playback, navigation, save, reload, undo/redo, and deletion.

Highlights

  • Local video and URL workflows in one desktop app.
  • Native PyAV frame preview with crop selection and subtitle overlay.
  • CPU and Nvidia GPU VideOCR editions.
  • 31 alphabetically listed OCR language choices, including common Asian languages.
  • Correct Simplified and Traditional Chinese VideOCR language mapping.
  • Subtitle import, cue timing edits, undo/redo, and SRT export.
  • Bold, italic, underline, and colour styling for selected subtitle text or whole cues.
  • Safe styled-subtitle rendering in both browser and native desktop previews.
  • Editor shortcut tooltips for formatting, playback, navigation, save, reload, undo/redo, and deletion.
  • yt-dlp format and site-subtitle discovery.
  • Project library, storage controls, activity rows, local logs, and crash logs.
  • Dark and light themes with persisted settings.
  • English and Simplified Chinese app interfaces.
  • Static self-identifying language choices (English and 中文) in the app and installer.
  • A complete Simplified Chinese README linked from the main project README.
  • English or Simplified Chinese can be selected on the installer's first screen.
  • The installer language becomes the app language on first launch and can be changed later in Settings.

Choose an Installer

  • CPU is the safest default and does not require an Nvidia GPU.
  • CUDA 12.9 is for supported Nvidia GTX 16 through RTX 50 systems.

Installing another edition replaces the app and OCR runtime while preserving
the user's workspace under %LOCALAPPDATA%\SubtitleYC\workspace.

Known Limitations

  • This is an early release and may still contain crashes or UI defects.
  • OCR accuracy depends on language, image quality, crop, and source frame rate.
  • Video websites change independently; yt-dlp workflows can require app updates.
  • The GPU installer is large because it includes the CUDA OCR runtime.
  • These installers are not Authenticode-signed. Windows may show an unknown-publisher warning; compare the SHA-256 digest shown by GitHub before running them.

Verify the Download

GitHub displays a SHA-256 digest beside each installer asset. To calculate the
digest of a downloaded installer in PowerShell:

Get-FileHash .\SubtitleYC-0.5.0-windows-cpu-setup.exe -Algorithm SHA256

Compare the result with the digest shown on the release page before installation.

Please report reproducible problems through the issue forms. Do not attach
private media or unredacted logs.
