VisoMaster Fusion 3.8.0

Highlights

• Timeline zoom (new): an advanced zoom system that dynamically scales the video timeline for frame-precise navigation, with exponential zoom scaling, playhead-centered scroll synchronization, and a configurable Max Visible Frames setting (10–100) that drives the maximum zoom based on video length.
• Provisional state tracking (new): the timeline now gives intelligent visual feedback for unsaved parameter changes — the playhead turns soft yellow when changes are pending, and the groove is colored by marker segment (alternating purple/blue), with caching to keep overhead low.
• Marker colors (new): timeline markers now support colors, making it easier to visually organize and distinguish sections.
• ReF-LDM Denoiser — standalone module (new): the diffusion denoiser was extracted into its own FaceDenoiser class (app/processors/face_denoiser.py), encapsulating the UNet, VAE encoder/decoder, KV extractor and DDIM scheduling. It runs as a dedicated pass before and/or after the restorers, with Single Step (Fast) and Full Restore (DDIM) modes, an Exclusive Reference Path option, and a fixed Base Seed for consistent noise across frames. Model loading is thread-safe with unload deferred during video playback.
• New denoiser color controls (new): per-pass Color strength slider (0–100) and a Color Transfer Type selector with five modes — CDF Histogram, CDF Histogram (Masked), Reinhard Transfer, Reinhard Transfer (Masked) (default), and AdaIN (Core Masked).
• Mouth cavity blending (new): a Mouth Original Cavity Blending control (0.0–1.0) blends between the artificial cavity shadow and the original aligned mouth texture for more natural mouths in high-fidelity restores.
• Recast Relative mode (new): expression transfer can now be applied relative to the source, for more natural, motion-preserving results.
• Recast Advanced mode (new): fine-grained, per-region expression multipliers (rigid/structural points, eyes, eyebrows, cheeks, lips/mouth, jaw) plus crop-border feathering for seamless blending.
• Webcam resolution control: added a webcam resolution option.
• Performance & fidelity: VRAM-fragmentation and color-transfer overhaul across faceutil, the frame worker, restorers and masks (GPU LUT-based histogram matching, Kornia local-warp paste-back, pre-allocated DDIM buffers, in-place tensor ops), plus a Recast FP32 fix and further Recast performance work.
• Fixes: frame-edits fix, output-folder skip for markers, typing fix, and removal of the Recast Smoothing option.

Changelog by version

3.8.0

Timeline zoom control (timelineZoomSlider) — dynamically scale the video timeline for frame-precise navigation:

• Exponential zoom scaling with real-time label updates.
• Intelligent scroll synchronization that keeps the playhead centered.
• Max zoom calculated dynamically from video length and the Max Visible Frames setting.
• Deferred initialization for smooth, responsive performance.

Provisional state tracking — intelligent visual feedback for unsaved changes:

• Automatically detects when parameters differ from the last saved marker state.
• Playhead turns soft yellow when changes are pending.
• Groove is colored by marker segment (alternating purple/blue).
• Intelligent caching to minimize performance overhead.

UI/UX improvements:

• Marker colors for timeline markers.
• Timeline controls wrapped in a QScrollArea for better viewport management.
• New Max Visible Frames setting (10–100) for user-controlled zoom behavior.
• Timeline elements now hide/show based on media type (shown for videos, hidden for images).

3.7.0

Denoiser separation — the diffusion denoiser is now a standalone FaceDenoiser class (app/processors/face_denoiser.py, ~823 lines) extracted from ModelsProcessor:

• Encapsulates the UNet, VAE encoder/decoder, KV extractor and DDIM scheduling.
• Thread-safe model loading with smart unload deferral during video playback.
• Single Step (Fast) and Full Restore (DDIM) modes, before and/or after the restorers.
• Built-in color transfer, pixel sharpening and histogram-matching post-processing.

New denoiser UI controls (denoiser_layout_data.py):

• DenoiserColorSlider (0–100, default 100) to tune color-correction strength per pass.
• DenoiserColorTransferTypeSelection with five modes: CDF Histogram, CDF Histogram (Masked), Reinhard Transfer, Reinhard Transfer (Masked) (default), AdaIN (Core Masked).

Mouth enhancement (face_masks.py):

• MouthOriginalCavityBlendingDecimalSlider (0.0–1.0, default 0.0) blends between the artificial cavity shadow and the original aligned mouth texture for more natural high-fidelity results.

Color-transfer algorithm overhaul (faceutil.py):

• Clearer method names: histogram_matching_DFL_Orig → apply_reinhard_color_transfer; histogram_matching_DFL_test removed; apply_adain_color_transfer updated.
• GPU-accelerated LUT-based histogram matching (256-bin lookup tables).
• Thread-safe caching for Gaussian/Laplacian kernels and faded masks.
• paste_back_adv optimized to use Kornia local warping (no full-frame padding).
• get_rotation_matrix moved to the modern torch.linalg.svd API.

Performance optimizations:

• VRAM-fragmentation fixes: removed per-frame v2.Resize instantiation in favor of functional wrappers.
• Disabled antialias=True on mask resizes to prevent ringing artifacts.
• BICUBIC high-fidelity upscaling in face restorers before normalization.
• Pre-allocated loop buffers in DDIM sampling (no mid-loop tensor creation).
• Smart KV-extractor unload deferred until after batch processing.
• In-place tensor operations (.clamp_(), .mul_()) to reduce memory overhead.

Code cleanup & modernization:

• Moved large landmark/ArcFace data arrays into models_data.py constants.
• Removed unused imports and stray non-English comments.
• Added comprehensive type hints (-> torch.Tensor, Optional[...]); typing fix.
• Fixed deprecated torch.svd → torch.linalg.svd, with clearer error messages/paths.

3.6.5

• Removed Recast Smoothing.

3.6.4

• Recast Advanced mode: independent per-region expression multipliers (structural, eyes, eyebrows, cheeks, lips, jaw) and crop-border feathering.
• Frame-edits fix and further Recast optimization.
• Enhancement to defaults.

3.6.3

• Recast Relative mode.

3.6.2

• Recast fix (FP32 mode).
• Added webcam resolution option.
• Output-folder skip for markers.
