VisionDepth3D v3.5 Release

1) Depth of Field (DOF) – Rewritten and Stabilized

• Fully rewritten as a GPU-accelerated, multi-level Gaussian pipeline
• Uses per-pixel interpolation between blur levels for smooth transitions
• Added motion-adaptive focal tracking:
  • Exponential moving average (EMA) for stable focus
  • Deadband to ignore micro noise
  • Max-step limiter to prevent sudden focus jumps
• DOF now applies after stereo warp using warped per-eye depth
• DOF slider maps directly to max blur; setting it to 0 disables DOF
• Result: smoother bokeh, no ring artifacts, more natural focal transitions

2) Audio Tool – Revamp and Codec Control

• Added progress bar for encoding and attaching audio
• Codec and bitrate can now be selected before muxing
  • aac (default) and libmp3lame supported
  • Configurable bitrate (128k, 192k, 320k)
• Added offset slider for real-time sync adjustment
• Clear distinction between copy vs re-encode:
  • If codec/bitrate unchanged → fast copy (-c copy)
  • If changed → re-encode
• Safe handling of long videos (2+ hours) with progress feedback

3) Color Grading – GPU Accelerated and Integrated

• Introduced GPU-accelerated color grading (apply_color_grade) with:
  • Saturation
  • Contrast
  • Brightness
• Color grading now applies after stereo warp and DOF, before packing
• Added Preview GUI sync:
  • Sliders update live in preview with debounced re-rendering
  • Two-way binding with main UI controls
• Preset/save/load support extended to include color grading
• Result: fine-tune the image directly inside VD3D without external tools

4) Stereo Separation (IPD Adjustment) – New 3D Control

• Added Interpupillary Distance (IPD) adjustment slider
• Works as a global scale factor on pixel shifts (foreground, midground, background)
• Allows creators to:
  • Increase IPD for stronger 3D on large screens or VR
  • Reduce IPD for comfortable viewing on smaller displays
• Fully integrated into:
  • Preset system (save/load)
  • Preview GUI with real-time feedback
  • Tooltip and i18n system
• Result: match stereo depth strength to your display environment

5) General Fixes and Stability

• Fixed tensor size mismatch crash in DOF when depth/resolution mismatched
• Preview GUI sliders now wire correctly to main GUI sliders
• Minor UI consistency fixes across tools
• Language files clean-up:
  • Removed duplicate keys and aligned all translations with en.json
  • Verified FR/DE/ES/JA language packs
  • Added missing entries (Apply Entries, Start Batch Render, scene detection, etc.)

6) New Session Additions – ONNX Pipeline and UI Enhancements

• ONNX Integration
  • Converted Video Depth Anything (pth → onnx) for faster inference
  • Optimized ONNX pipeline path for efficient runtime
• UI Enhancements
  • New start and end time controls inside Encoding Settings
  • Render short clips or preview segments without running full videos
  • Inputs section refactored into its own dedicated frame for clarity
• Result: streamlined workflow for experimenting with models, and flexible render ranges for testing

Summary

v3.4 gave creators fine-grained depth and subject control.
v3.5 brings cinematic polish with stabilized DOF, a true audio tool with sync and codec options, a GPU color grading suite, stereo separation (IPD adjustment) for display comfort, and ONNX pipeline plus clip rendering support for faster experimentation.
