Bug Fixes

• macOS: App didn't function for users without ffmpeg pre-installed
• Performance: The <16GB VRAM optimization introduced in a previous version caused a performance regression for users with high-VRAM GPUs — the optimization is now only active when VRAM is below 32GB
• Video Editor: Regression in gap fill generations causing generations to error
• Video Editor: Regression from previous version — pure audio tracks could not be dragged and dropped
• Video Editor: Video assets could be dropped onto audio tracks
• Video Editor: Panel resizing was unresponsive on first attempt when entering the editor
• Video Editor: Gap fill generation properties (resolution, fps, duration) were incorrect and out of sync with Gen Space properties
• Video Editor: Text clip properties panel incorrectly showed video clip properties
• Video Editor: Source monitor controls were missing a loop button
• Video Editor: Asset panel lasso was unresponsive to scroll when dragging out of panel bounds
• Video Editor: Could not start a lasso selection from a gap fill area in the timeline
• Video Editor: Custom asset bin creation didn't work
• Settings: Text encoder download showed a misleading UI — replaced with an accurate progress bar
• Settings: Removed configurations that were not connected to any functionality
• First Launch: LTX API key set during first launch was not reflected in the UI without a restart
• LTX API: Insufficient funds error now shows a dedicated message with a button linking to the LTX API console to purchase credits
• A2V: Local generations were unnecessarily restricted to landscape aspect ratio and specific resolutions — restrictions removed
• Backend: In specific failure cases, a launch error could appear with no message and a non-functional retry button

Improvements

• App version is now logged at startup in reported log files, aiding bug investigation
• Added volume control for video assets directly from the Gen Space asset thumbnails

Full Changelog: v1.0.4...v1.0.5

What's Changed

• Integrated model layer streaming support, reducing peak VRAM usage from ~26 GB to ~11 GB
• Video Editor performance improvements enabling smooth playback and responsiveness even in complex projects (e.g. 64+ assets)
• Video Editor bug fixes:
  • Improved audio playback stability
  • Improved clip transition rendering consistency
• Video Editor architecture improvements:
  • Refactored core systems for cleaner and more maintainable code
  • Established a robust state management architecture with reliable undo/redo and project persistence
  • Simplified multiple code paths for improved clarity and maintainability
  • Added coding agent Skill integration aligned with the new architecture (Cursor, Claude Code, Codex)
• Improved model download performance
• Removed legacy Playground screen for a more streamlined app experience
• Codebase integrity improvements:
  • Strengthened type safety on both server and Electron layers
  • Introduced a unified OpenAPI-based contract between backend and frontend
