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.

• 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.

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.

  These rules are now automatically cleaned up after each capture, maintaining consistent export performance throughout the video.

Quran Caption v3.7.51

This update significantly expands Hifz repetition customization, improves access to audio effects, and adds more flexibility to Arabic and translation styling.

---

Hifz Repetition

• Added a new Linked Repetition mode for memorization.

  In addition to standard repetition, you can now create cumulative sequences that progressively connect verses, such as:

  Verse 1 → Verses 1–2 → Verse 2 → Verses 2–3.

• Added advanced customization for Hifz sequences:

  • Choose how many verses to link together.
  • Set separate repetition counts for individual and linked groups.
  • Configure different repetition counts for the first and last groups.
  • Optionally play the entire passage at the beginning and end.
  • Configure separate pauses between repetitions and between groups.
  • Choose which subtitles to include in practice repetitions.

• Improved Word-by-Word timing preservation when generating repeated verses.

---

Audio Effects

• Audio effects can now be opened directly by right-clicking an audio clip in the timeline.

  Select Noise Reduction, Voice Clarity, Echo or Reverb to open the effects editor with the corresponding clip and effect already selected.

• Added an AI Segmentation recommendation when applying audio effects to a project without subtitles.

  Quran Caption now recommends aligning the original recitation before applying effects, helping preserve subtitle timing accuracy.

---

Arabic Interface

• Added the Zain font to the Arabic interface for improved readability.

---

Text Styles

• Extended the minimum word spacing and letter spacing values to -30.

  This provides greater flexibility when adjusting Quranic text and translation layouts.

  Existing projects are automatically updated to support the new limits without changing their current styling.

Quran Caption v3.7.50

This update introduces full Arabic localization, new audio effects for Quran recitations, per-clip video styling, customizable editing shortcuts, and several preview and export improvements.

---

Arabic Localization

• Quran Caption is now fully available in Arabic.

  The entire application has been translated, with right-to-left layouts adapted across the homepage, editors, settings, timeline and other interfaces.

---

Audio Effects

• Expanded the previous noise reduction tool into a complete audio effects editor.

  You can now apply four FFmpeg effects to your recitations:

  • Noise Reduction: reduce constant background noise.
  • Voice Clarity: remove low-frequency noise and improve vocal clarity.
  • Light Echo: add a subtle echo to the recitation.
  • Light Reverb: add a gentle sense of space.

• Each effect has adjustable parameters and a 10-second audio preview, allowing you to listen to the result before applying it.

  The processed audio is saved as a new WAV file and replaces the selected timeline clip's source without modifying the original recording.

---

Per-Clip Video Styles

• Added individual styling for image and video clips.

  You can now select a media clip and customize its layout independently, including:

  • Fill Frame, zoom and positioning
  • Video frame dimensions, color, rounded corners and softness
  • Background overlay settings

  These settings are applied independently to each clip in both the preview and exported video.

---

Keyboard Shortcuts

• Added configurable shortcuts for opening the quick editor at the timeline cursor.

  You can assign separate shortcuts to open the subtitle editor, translation editor, WBW timestamp editor, or WBW style and translation editor.

• Added configurable shortcuts to jump directly to the previous or next subtitle marked for review.

---

Video Preview

• Improved subtitle positioning and resizing.

  A new center grip makes it easier to move selected subtitles without accidentally resizing them.

• Added visual collision warnings.

  When dragging subtitles with anti-collision enabled, overlapping subtitles are highlighted in red, making positioning issues easier to identify.

• Fixed individual subtitle height and text sizing overrides not being correctly respected during automatic font fitting.
