Hello VD3D users 👋

It’s been another month, and I’m excited to share VisionDepth3D v3.8. This update focuses on depth stability, model compatibility, and overall polish across the UI and backend. Below is a breakdown of what’s new.

1) Depth Estimation Tab

Depth Models

• Fixed ONNX model loading:
• Distill-Any-Depth (inference resolution 518×518, batch size 8)
• Video Depth Anything (inference resolution 512×288, batch size 8)
• Implemented LBM depth model (development version). Thanks to Aether for the implementation fix.
• Removed depth models from the dropdown that returned no d_type.
• Fixed Hugging Face model downloads and caching so zoo models consistently save inside the app weights/ directory (no more extra .cache downloads).
• Updated Transformers image processor loading to prefer use_fast=True when available (with automatic fallback when unsupported).

Depth Backend

• Implemented temporal smoothing in the depth pipeline to reduce flicker and improve temporal stability of depth map output.
• Packaged VisionDepth3D.exe with Distill-Any-Depth (ONNX), Video Depth Anything (ONNX), and Depth Anything v2 Giant weights.

2) 3D Render Tab

UI Fixes

• Added buttons for encoder settings and processing options.
• Implemented multi-language support and tooltips for new dialog boxes.
• Adjusted preview image window size and video info layout to prevent window overflow.
• 3D tab columns now stack correctly when resizing the window on smaller screens.

3D Backend

• Reworked Auto Crop Black Bars to use first-frame detection with cached crop reuse.
• Prevents per-frame crop jitter and depth/frame misalignment.
• Improves stability for cinema content with subtle letterboxing.
• Keep Audio checkbox now respects the user-selected output container instead of forcing MP4.

Frametool Backend

• Reworked Frametool backend to support SSResNet models for feature model integration.

Console Improvements

• Standardized startup console messages to clearly reflect which subsystems are initializing (Torch, depth estimation, upscaler, external 3D pipeline, language, settings).
• Unified compute device reporting across pipelines for consistent and clearer console output.
• Suppressed optional xFormers dependency warning on startup.
• Prevented duplicate language loading during settings restore.

Summary

v3.8 focuses on stabilizing depth estimation, improving model compatibility, and refining the 3D Render tab UI with better layout behavior, clearer diagnostics, and improved localization support.

Back up your weights/ and presets/ folders before uninstalling v3.7. Then run VisionDepth3D_Setup_Downloader to download the official VisionDepth3D v3.8 Windows installer and required .bin files. (Optional but recommended) Clear the Hugging Face cache to free space and avoid duplicate model downloads: C:\Users\YOUR_USERNAME\.cache\huggingface
