Quran Caption v3.7.61

This update introduces a completely new local AI Segmentation model, with faster and more accurate Quran alignment, improved Word-by-Word timings, and several reliability fixes.

New Local AI Segmentation

  • Added a completely new local Quran AI Segmentation model

    This new offline alignment engine was developed and contributed by a brother who wishes to remain anonymous. May Allah reward him immensely for his work.

    It replaces the previous local word-timing aligner and performs Quranic speech recognition, ayah matching, and Word-by-Word timestamp alignment directly on your computer.

  • Improved local alignment accuracy and reliability

    The new engine includes improved Quran text matching and CTC forced alignment, with stricter word and phoneme ordering to produce more consistent timings.

  • Significantly improved performance

    Fast mode is now enabled by default and automatically takes advantage of the available CPU topology to process recitations more efficiently.

  • Improved progress reporting during local segmentation

    Progress now advances consistently throughout the alignment process instead of moving backwards or reporting misleading stages.

    Once the required models and dependencies are installed, the segmentation engine runs locally without requiring an internet connection.

Project Creation

  • Added video format and resolution selection when creating a project

    You can now choose between:

    • Landscape 16:9
    • Portrait 9:16
    • Square 1:1
    • Custom dimensions

  • Added resolution presets from 720p up to 2160p (4K).

  • New projects now automatically receive subtitle layout defaults adapted to their orientation.

    Portrait projects use smaller Arabic and translation text sizes and adjusted positioning to better fit vertical videos.

  • Modernized the video dimension controls in the Style editor with the same Landscape, Portrait, Square and Custom format options.

Video Preview

  • Added a seekable playback progress bar.

    You can now click or drag through the video directly from the preview controls.

  • Added 10-second backward and forward buttons for faster navigation.

  • Playback now automatically restarts from the beginning when pressing Play at the end of the video.

  • Improved the preview controls layout and appearance.

Istiadha Styles

  • Added 16 calligraphic Istiadha styles.

    Istiʿadha subtitles can now use dedicated calligraphic designs instead of the regular Arabic font.

  • Added independent Istiadha scaling.

    Calligraphic Istiadhas can be resized independently from the rest of the Quran subtitles in both preview and export.

Arabic Interface

  • Fixed vertical panel resizing moving in the wrong direction when using the Arabic RTL interface.

Preview Fixes

  • Fixed visually merged subtitles with empty translation ranges not being cloned correctly in the preview.
