Lumislide 1.0.0

Lumislide 1.0.0

First public release: turn a folder of photos and videos into an MP4 slideshow
with automatic transitions, Ken Burns, titles and music. (macOS 15+, Apple Silicon;
prebuilt Lumislide.app, ad-hoc/development signed — open via Right-click > Open.)

Highlights

• 11 transitions (auto, deterministic) + per-slide override; Ken Burns with face-aware focus.
• Music: playlist of several tracks (loop), 1 s fades around videos, ducking under video audio.
• Video slides keep their own audio and play at their true duration.
• Titles, aspect ratios (16:9 / 4:3 / 9:16 / 1:1), live preview.
• Export to MP4 (H.264/H.265) with built-in presets (720p / 1080p / 4K / Instagram)
  and a user resolution list; progress, cancel, size estimate.
• Editor: multi-select (Shift = range, Cmd = toggle), batch delete/move, per-slide
  duration, Undo/Redo.
• Localized UI (EN/RU).

Fixes

• Video slides were truncated to the photo duration — fixed (shared duration resolver + cache).
• Preview no longer drops transition frames (frames rendered off the main thread).
• Music fade reduced 2 s -> 1 s around videos.
• Menu items (New Project, Add Media, Properties, Preview, Export) silently did nothing — fixed.
• "Settings" menu item did nothing — now opens the settings window.
