Quran Caption v3.7.30

This update introduces direct subtitle editing from the video preview, improves Quran alignment and batch processing, and significantly improves 4K export performance.

Preview Editing

  • Added direct subtitle resizing from the video preview

    Arabic and translation subtitles can now be resized directly using width and maximum-height handles.

    Corner handles support two-axis resizing, and subtitle dragging has been optimized to remain responsive while editing.

  • Added quick subtitle style controls on right-click

    Essential Arabic and translation styles can now be changed directly from the subtitle context menu without opening the full Style editor.

    This includes font family, font size, color, alignment, verse number settings, and, where applicable, Riwayah, Mushaf, decorative brackets and Word-by-Word settings.

  • Fixed composite style controls applying incorrectly when editing selected custom text elements.

Quran Alignment

  • Reworked Quran Universal Aligner integration (by @Hetchy)

    Cloud alignment now uses the new API v1 pipeline with secure Hugging Face account quota support.

    The new pipeline avoids redundant alignment work and improves reliability.

  • Batch projects now use the native alignment pipeline

    Multiple alignment jobs can be processed concurrently with controlled rolling uploads and isolated temporary audio files.

AI Segmentation

  • Improved manual token controls in the segmentation editor. (by @Hetchy)

  • Fixed incorrect coverage-gap detection after a completed Al-Fatiha.

Export

  • Improved Balanced export quality and performance

    Balanced mode now uses a higher-quality NVENC configuration when available, with a high-quality libx264 fallback.

  • Significantly improved 4K caption fade performance by reusing encoded image data during rendering.

  • Export review warnings now only report active issues from translations that are actually visible in the video.

Project Assets

  • Added bulk deletion for selected project assets.

FFmpeg

  • Quran Caption now warns when the installed FFmpeg version is outdated.

Updater

  • Fixed release notes sometimes not appearing immediately in the update window.
