Quran Caption v3.7.64

This update adds advanced media download options, improves the new local AI Segmentation engine, and fixes export performance on macOS.

---

Media Downloads

• Added advanced options when downloading media from YouTube.

  You can now:

  • Download only a specific excerpt using start and end timestamps.
  • Choose the video quality from 360p up to 4K.
  • Choose the audio quality from 96 to 320 kbps.
  • Download video without audio.

---

Local AI Segmentation

• Improved the new offline AI Segmentation engine with more reliable Quran detection and Word-by-Word alignment.

• Added a button to copy the complete AI Segmentation error.

  This makes it much easier to send the full error details when reporting a problem.

---

Export

• Fixed macOS video exports becoming progressively slower during frame capture.

  Temporary font rules are now cleaned up after each captured frame.

Quran Caption v3.7.63

This update improves the reliability of local AI Segmentation and adds a fallback alignment option.

---

Local AI Segmentation

• Added the previous offline aligner as a second selectable local segmentation option.

• Improved error reporting for the new local AI Segmentation model.

  If the local Python process crashes or fails, Quran Caption now displays the real exit code and available crash details instead of a generic segmentation error.

Quran Caption v3.7.62

This update mainly includes hotfixes for the new local AI Segmentation engine and a new theme setting.

---

Local AI Segmentation

• Improved the installation and setup of the new offline Quran segmentation engine.

• Added automatic portable Python setup when needed.

• Improved compatibility on systems where native Kaldi is unavailable.

• Fixed several setup, model validation, navigation and subtitle workflow issues.

• Improved the AI Segmentation wizard on smaller screens.

---

Theme

• Added a new setting to use a dimmed background behind dialogs instead of the default background blur.

  This can improve performance on some systems.

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.

• 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.

  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.

Quran Caption Mobile v1.1.72

This hotfix resolves an issue that caused video exports to become progressively slower during frame capture.

---

Hotfix

• Fixed frame capture slowing down as video export progressed.

  Font rules were accumulating after each captured frame, making subsequent captures increasingly expensive.

  These rules are now automatically cleaned up after every capture to maintain consistent export performance, especially for longer videos.

Quran Caption Mobile v1.1.71

This hotfix improves Android video export stability by reducing memory usage during screenshot capture.

---

Hotfix

• Fixed Android WebView crashes during video export.

  Screenshot memory is now released after each captured frame, preventing image caches from growing continuously throughout the export.

  The reusable screenshot context is also periodically reset to further reduce memory consumption, particularly during long or high-resolution exports.

Quran Caption v3.7.52

This hotfix resolves a performance issue that caused video exports to become progressively slower during the frame capture stage.

---

Hotfix

• Fixed frame capture becoming slower as video export progressed.

  Font rules were accumulating after each captured frame, causing subsequent captures to take increasingly longer.
