# 🛠️ VisionDepth3D v3.2.X – Performance & Stability Update

## Changelog:

### Fixed UI Freezing During Folder Processing
- Resolved a bug where the GUI would freeze when processing a folder of videos for depth generation.
- Properly offloaded batch size parsing and folder selection to the main thread, with core logic in a background thread.

### Removed Redundant Batch Logic in Folder Processing
- Cleaned up double handling of `batch_size` logic in `process_video_folder()` and `process_videos_in_folder()`.
- Now batch size is handled only once, before launching the background thread, improving clarity and reliability.

### Refactored ONNX Model Loader
- Rebuilt the `load_onnx_model()` function to support both rank-4 and rank-5 ONNX models.
- Adds automatic padding for 32-frame models (e.g. Marigold) and returns predictions as `torch.tensor` objects.
- Includes robust shape detection, better error handling, and future support for diverse ONNX pipelines.

* Update VisionDepth3D.py

🎬 Integrated PySceneDetect into FrameTools GUI for Scene-Based Splitting

- Added support for automatic scene detection using PySceneDetect.
- Clips can now be segmented into manageable scenes directly from the FrameTools tab.
- Enables smarter depth processing by allowing fine-tuned 3D rendering per scene.
- Added user-adjustable threshold slider (NOTE: fixed logic to reflect correct cut behavior).

* Update merged_pipeline.py

FrameTools Tab: Improved Frame Extraction Workflow

- Added directory selector to choose custom output location for extracted frames.
- Switched to FFmpeg for frame extraction, significantly improving speed and reliability.

changed title tag to 3.2.5

* v3.2.6 – Add support for batch and single video 3D rendering

- Implemented dual input modes: render from a single video or from a list of video/depth map pairs.
- Added mode selector dropdown (Single / Batch) with dynamic UI updates to show relevant input fields.
- Updated label system to reflect selected inputs per mode.
- Ensured compatibility with preview and 3D render workflows for both modes.
- Refactored processing logic to call existing 3D render function per item in batch.
- GUI layout improved for cleaner alignment of input controls.

* v3.2.6

* v3.2.6 – Add IPD factor multiplier for parallax scaling

- Introduced `ipd_factor` parameter to control stereo separation intensity.
- Applies uniform scaling to foreground, midground, and background shift values.
- Useful for testing different IPD settings or achieving exaggerated parallax effects.
- Included default fallback (1.0) for backward compatibility.
- Note: This is a synthetic IPD adjustment (non-metric depth), primarily for aesthetic tuning.

*will introduce into UI at a later date, set to 1.0 atm*

* v3.2.6 – Add audio offset support to Audio Attacher tool

- Added slider to GUI for setting custom audio offset (positive or negative)
- Updated FFmpeg integration to shift audio stream relative to video duration
- Useful for syncing misaligned audio during reattachment process

* v3.2.6 – Add Japanese Language Support

* v3.2.6 - Add missing code and update program version title

Fully implemented Japanese language to work, new batch process in 3D render tab had missing elements for the language support

v3.2.6 Changelog

* Update Changelog.md

* v3.3

### 3D Pipeline Improvements – v3.3

- **Black Bar Handling**
  - Detects and crops letterbox bars before depth estimation.
  - Re-adds bars post-processing with neutral depth to prevent stereo artifacts.

- **Depth Stability & Quality**
  - Added temporal depth filtering (EMA) for smoother frame-to-frame depth.
  - Percentile-based normalization for consistent depth range across scenes.
  - Midtone shaping to enhance perceived depth and separation.
  - Optional curvature enhancement for more natural object roundness.

- **Stereo & Parallax Control**
  - Dynamic IPD scaling based on scene depth variance.
  - Shift smoothing for foreground, midground, and background layers.
  - Edge-aware masking and feathering to reduce tearing/ghosting.
  - Subject-tracked zero-parallax plane with eased floating window adjustments.
  - Optional dynamic convergence bias tied to subject position.

- **Image Quality**
  - GPU-accelerated depth-of-field with multi-level Gaussian blending.
  - Brightness-preserving sharpening with anti-clipping.

- **Framing & Output**
  - Per-frame optional black bar cropping in the stereo stage.
  - Aspect-ratio-safe resizing and padding for per-eye frame alignment.
  - Multiple stereo formats supported (Full-SBS, Half-SBS, VR, anaglyph, interlaced).

- **Encoding & Stability**
  - FFmpeg pipeline over stdin with correct CRF/CQ handling.
  - Graceful cleanup and resource release on completion or cancel.
  - Detailed logging for crop, skip, and encoder decisions.

* v3.3

### Depth Pipeline Improvements – v3.3

- **Letterbox Detection & Cropping**
  - Added `ignore_letterbox_bars` option to automatically detect top/bottom black bars.
  - Crops bars before sending frames to the depth model for cleaner predictions.
  - Stores bar metadata (top/bottom size, original resolution) in a `.letterbox.json` sidecar file.

- **Preserve Original Resolution**
  - After depth prediction, resizes the depth map back to the cropped region size.
  - Re-adds original bars with a neutral depth value to avoid 3D distortion.
  - Ensures depth output matches original width/height exactly.

- **Crash Prevention & Safety Checks**
  - Resets bar values to zero if detections are invalid (too large or empty frames).
  - Handles fade-ins and all-black first frames without breaking processing.

- **Grayscale Conversion Refactor**
  - Unified `convert_depth_to_grayscale()` into a single reusable function.
  - Works with `PIL.Image`, `torch.Tensor`, and `numpy.ndarray`.
  - Includes NaN checks, shape handling, and safe fallbacks for bad frames.

- **Output Consistency**
  - Standardized grayscale depth conversion across all depth output paths.
  - Maintains uniform depth range handling for downstream 3D processing.
