Quran Caption v3.7.40

This update adds audio noise reduction, timed image clips, simplified export quality modes, global playback speed controls, and several subtitle editing improvements.

---

Audio

• Added a new noise reduction tool

  Select an audio clip from the timeline and Quran Caption can now reduce constant background noise using FFmpeg.

  A cleaned WAV file is created and automatically replaces the selected clip source while keeping the original file untouched.

---

Video Timeline

• Images can now be used as timed clips directly in the video track

  Image clips can be moved and resized on the timeline just like video clips.

• Images and videos can now be mixed together in the same background timeline and exported correctly.

  When adding an image to an empty video track, you can choose between using it as the full-video background or as a regular timed clip.

Export Quality

• Simplified export performance modes

  Fastest and Low CPU have been replaced with two clearer options:

  • Balanced is now the default and uses hardware acceleration when available for faster exports.
  • Max Quality uses CPU-only software encoding for the highest visual quality.

• Fixed media without an audio stream causing issues during export by automatically using matching silence when needed.

• Fixed subtitle exports using outdated translation targets from previous selections.

Playback

• Added global preview playback speed controls

  Playback speed can now be changed from the advanced title bar tools with 0.75x, 1x, 1.5x, 1.75x and 2x options.

---

Subtitle Editor

• The video preview in the subtitle editor can now be vertically resized using a draggable divider.

  The selected preview height is saved across sessions.
