ScreenSage Pro 0.3.3 fixes a Metal rendering failure that could occur when a camera-only layout transitions to or from another layout during export.
Fixes
Camera-Only Layout Transitions
Fixed exports and preview composition for projects where a camera-only global layout or layout range fades into or out of another layout. The renderer now skips non-renderable subpixel screen layers during transition endpoints instead of asking MetalPetal to create invalid textures.
Export Stability
Improved Metal composition guards for zero-sized, non-finite, or near-zero screen rectangles so camera-only transitions no longer fail with MTIErrorInvalidTextureDimension.
ScreenSage Pro 0.3.2 includes timeline multi-selection, pointer-anchored timeline zooming, track-level selection controls, standard mouse support for horizontal scrollbars, smoother preview playback, expanded layout controls, and fixes for preview/export cropping, timeline display, PiP corner radius, project reopening, recording, close-time autosave, and performance behavior.
Updates
Timeline Multi-Selection
Added support for selecting multiple timeline items and moving or adjusting them together.
Pointer-Anchored Timeline Zoom
Updated timeline zooming so zoom changes are centered around the pointer position.
Track-Level Selection
Added selection controls to the timeline track header column.
Horizontal Scrollbars
Added standard mouse support for horizontal scrollbars across the app.
Project Preview
Updated recent project previews on the launch screen.
Timeline Editing
Added double-click handle expansion to extend clips to their nearest boundary, custom music picker access from empty music tracks, and improved track header sizing, empty-track hints, and merge button layering.
Camera Layout Controls
Refined Focused Camera layout selection and added clearer picture-in-picture size and position controls.
Preview Playback
Improved preview playhead smoothness and reduced unnecessary frame-level preview logging unless debug switches are enabled.
Fixes
Preview and Export Cropping
Fixed cropping issues that could occur during preview or export when projects use different aspect ratios.
Timeline Display and Interaction
Fixed music waveform bounds, thumbnail waveform alignment, initial timeline zoom jumps, tooltip overlap, slicing-related crashes, timeline undo step hiding, and playhead/timeline scroll position after reopening a project.
PiP Corner Radius
Fixed saved project behavior where picture-in-picture corner radius settings could fail to persist correctly, and fixed camera layout ranges overriding PiP corner radius unexpectedly.
Recording and Performance
Fixed keystroke recording display, repeat-key recognition, keystroke undo, and keystroke regeneration behavior, and optimized memory usage and timeline performance behavior.
Close and Autosave
Improved close-time handling for recording projects so autosave prompts and recent-project updates behave more reliably.
ScreenSage Pro 0.3.0 brings templates, sequences, Transform 3D, BGM, and recording layouts into a much more complete editing workflow.
Core Updates
Templates & Sequences
25 built-in templates now connect template preview, default timelines, and sequence workflows, making the path from recording to final cut much faster.
Transform 3D
This is more than a visual refresh. The new UI brings a stronger, smoother editing experience, and global Transform 3D now supports Lively Motion to keep frames from feeling too static.
BGM & Auto Beat Sync
ScreenSage Pro now includes 28 commercial-use background tracks across 6 style categories, and auto beat sync lets music actively drive cutting rhythm instead of just sitting underneath the edit.
Recording Layout System
The layout system now supports Screen+iOS, vertical 9:16, Stack, Focused Camera, Corner Cutout, and more, giving recordings much more presentation range.
Recording-to-Editing Layout Sync
Camera preview layout adjustments made during recording can now flow directly into the editing timeline, so you do not need to rebuild the same layout afterward.
iOS Mockups
42 iPhone and iPad mockups are now built in, making app demos, promo videos, and polished screen recordings much easier to package.
Custom Backgrounds & Color Library
You can now use custom background colors and a saved color library, making it easier to build a more intentional and consistent visual style.
Vertical Creation
More vertical templates and layout structures are now supported, making 9:16 and short-form video creation more practical.
Fixes & Improvements
Recording Performance
Improved recording performance and stability under heavier workloads to reduce stutter and rough edges while capturing.
Template Preview & Long-Video Performance
Improved template preview responsiveness, editor startup, and long-video editing performance for a smoother overall workflow.
Export Stability
Fixed a range of issues that could cause preview mismatches, export failures, or unstable output, including retimed audio fallback and WhisperLib export paths.
Camera Preview & Layout Stability
Fixed camera preview flicker, PiP recovery, layout refresh issues, ratio mismatches, and corner-radius inconsistencies so preview and final output stay more aligned.
Editor Polish
Continued refining the inspector, timeline, sidebar, and toolbar details to make everyday editing feel more streamlined.
