VisionDepth3D v3.8.2

This release brings major depth engine upgrades, large real-time performance gains, and important stability fixes across both offline rendering and live 3D preview.

Expect faster playback, cleaner depth output, improved codec reliability, and a smoother overall workflow.

New Depth Engines

Depth Anything 3 (DA3) Integration

  • Native DA3 backend (not Hugging Face pipeline based)
  • Supports DA3 Small, Base, Large, Giant, and Metric variants
  • Proper resolution handling and depth normalization
  • Faster warm-up and improved batching support

Video Depth Anything (VDA)

  • Sequence-aware video depth inference
  • Temporal processing for smoother depth output
  • Target FPS control for heavy footage
  • Unified post-processing with other depth engines

Performance Improvements

Live 3D

  • 40 to 70 percent FPS increase on most GPUs
  • Persistent GPU buffers eliminating per-frame allocations
  • Smoother depth refresh scheduling
  • Reduced jitter and stutter

Offline Depth and Rendering

  • Single-pass resizing reducing CPU overhead
  • Faster FP16 GPU inference
  • Optimized ONNX runtime sessions
  • FFmpeg piping enabled by default for faster encoding

Stability and Quality Fixes

ONNX Models

  • Fixed Distill-Any-Depth shape mismatch crashes
  • Enforced correct inference resolution (518×518)
  • Aspect-ratio safe preprocessing without stretching
  • Cleaner backend detection and logging

Letterbox Handling

  • Black bars no longer corrupt depth maps
  • Neutral depth fill prevents white banding artifacts
  • Stable detection across frames

3D Generator Improvements

  • Full render state reset per clip to eliminate drift artifacts
  • Smoother convergence and floating window behavior
  • Corrected output sizing for VR, SBS, and interlaced modes
  • Optional convergence crosshair overlay in Preview GUI
  • Cleaner encoding settings layout

GUI and Workflow Enhancements

  • Depth Estimation tab renamed to Depth Engine
  • Fixed preset loading from menu dropdown
  • Fixed Output Path menu action
  • Simplified File menu using preset system only
  • Built-in VisionDepth3D Updater in Help menu
  • Confirmation prompt before updating

Upgrade Note

Back up your weights/ and presets/ folders before uninstalling older versions.

Use VisionDepth3D_Setup_Downloader to install v3.8.2 and required .bin files.

Thanks to everyone supporting VisionDepth3D and helping shape each release.
