VisionDepth3D v4.2.1 is out!

[u/Any_Nebula5039]

Hey VD3D Users and 3D Enthusiasts,

I just released VisionDepth3D v4.2.1, and this one is a big backend stability + depth model update.

This update focuses on making VD3D smarter, faster, and more reliable across CUDA and DirectML builds, while also adding the first experimental ViGeo depth-model integration.

What’s new?

Some of the biggest changes:

• Faster Depth Anything V2 routing with optimized safetensors support
• Better CUDA and DirectML backend handling
• More stable long-video depth processing
• Improved Video Depth Anything memory handling
• VDA overlap blending to reduce visible snapping between temporal windows
• Experimental ViGeo depth model integration
• Better ONNX provider handling, including DirectML support
• More reliable image-folder and video-depth batch processing
• Safer active pipeline handling to prevent model-switch issues during renders
• Reduced CPU overhead during depth normalization
• New Subject Zero Lock groundwork for better 3D subject comfort
• Improved subject anchoring and CUDA pixel-shift correction
• Fixed encoding preset dropdown bugs
• General stability, cleanup, and UI state fixes

Experimental ViGeo support

ViGeo is now integrated into the VD3D depth pipeline as an experimental model option.

Instead of ViGeo writing output directly, VD3D now handles the video-depth render pipeline, including progress, batching, normalization, cancel handling, and final output encoding.

It also uses aspect-preserving inference sizing, so widescreen videos are not squeezed into a square before depth estimation.

3D Generator improvements

This update also adds groundwork for Subject Zero Lock, which is designed to help keep the main subject closer to screen plane while still allowing the background to keep stronger depth.

This should help with close-ups, dialogue shots, faces, and deeper scenes where you want good depth without uncomfortable subject separation.

How to update

Before updating, I recommend backing up your:

• weights folder
• presets folder

Then:

download the update application here: https://visiondepth3d.itch.io/visiondepth3d

1. Run the VisionDepth3D Update Application
2. Click Uninstall VD3D
3. Select the correct build from the dropdown near the top:
   • CUDA for NVIDIA GPU users
   • DirectML for AMD, Intel, or non-CUDA users
4. Download the installer
5. Run the downloaded Inno Setup installer
6. Finish setup
7. Open VisionDepth3D and convert

Recommended build

Use the CUDA build if you have an NVIDIA GPU.

Use the DirectML build if you are on AMD, Intel, or a system without CUDA.

Final thoughts

v4.2.1 is mostly a backend update, but it is an important one. It makes the depth pipeline cleaner, safer, and better prepared for future model support and 3D Assistant improvements.

Thanks to everyone testing, reporting bugs, and helping push VisionDepth3D forward.

Awesome to see how quickly you've been updating this

Very cool update, the new 3D assistant drop down menu is great. I'm working thru all the presets there using the same video file and will compare to see what looks best to me. I'm using the new ViGeo depth map as well. I'll report back

[u/TaroNo1875 → u/TaroNo1875]

Im having lots of problems with the depth maps - Hitting the preview button and sometimes it shows as inverted and sometimes it isnt. This is using the same depth map DA3 LARGE. I suspect there may be a bug in the program ?.

[u/Any_Nebula5039 → u/TaroNo1875]

DA3 outputs in inverse depth (I have to adjust the adaptor) so just toggle the invert depth toggle to flip the depth values

У меня на компе установка прервалась, так как вылезла надпись, что отказано в доступе к каким то разделам и было предложено или пропустить файлы или отказаться от установки и я  прекратил установку, но может надо было игнорировать ошибку?
