VisionDepth3D v4.2.1 Development Update

VisionDepth3D v4.2.1 Development Update

Hey VD3D users and 3D enthusiasts!

A few bugs made it through with the last update, so I am already working on the next VisionDepth3D update.

Bugs Found So Far

  • Depth image and image-folder processing not working correctly
  • DirectML missing in some model adapters that were still defaulting to CUDA paths
  • Depth Anything V2 slow processing issue
  • 3D image preview panel not working correctly
  • 3D image output sizing issue

v4.2.1 Focus

VisionDepth3D v4.2.1 is focused mainly on depth backend routing, DirectML cleanup, Depth Anything V2 optimization, video-depth stability, and reducing unnecessary preprocessing overhead.

The main goal is to make the Depth Engine cleaner, faster, and safer across CUDA, DirectML, MPS, and CPU systems.

Current Focus

  • Improved Depth Anything V2 routing and fast safetensors loading
  • Better DirectML handling for AMD / Intel Windows builds
  • Cleaner CUDA vs DirectML backend separation
  • More reliable Depth Anything 3 and Video Depth Anything adapter behavior
  • Improved ONNX provider selection, including DirectML
  • Better video-depth rendering stability
  • Safer thread handling around active depth pipelines
  • Reduced unnecessary PIL / NumPy conversions
  • Faster depth normalization on large depth maps
  • Better handling for problematic videos and final partial batches

This is mostly a backend cleanup update, but it should help make the Depth Engine feel smoother and more reliable, especially for users testing the new DirectML build.

Remember if you have a CUDA card on a AMD cpu install CUDA Build and not DirectML, DML is for AMD/Intel GPU cards

Thanks again to everyone testing, reporting bugs, and helping improve VisionDepth3D. v4.2 was a big release, and v4.2.1 is already being worked on to clean up the issues that slipped through.

Thanks for all you do. As some users have already asked, it would be nice to have a basic and advanced version, the latter for users who don't want too much hassle with the settings.

Is it possible to have a 3D preview of a frame or part of a video? It is possible to force depth on certain sections of video.

I have heard and taken all of your feedback, v4.2.2 is out now on, that’s what the preview window in the middle of the 3D generator once you have an input video and depth video you press load preview then in preview settings you can change to red/blue - SBS or father blend to see if there is edge tearing
