Summary

This package includes assets and tool for automation with ComfyUI. Assets are custom nodes and workflows, and automation is based on shellscripts for Git bash.

With release 2.0 the focus is switching from asset to the tool. Only one shell script is called now, that runs in the background, waiting for new video and image files to be processed. It will be explained below. No manual call of other scripts and workflows required.

On a modern PC, expect for a scaling one second of a 720p video to calculate one minute, and at least another minute to convert it afterwards to sbs.

Prologue

The software was developed by me, Fortuna, with lot of help from Iablunoshka, who is responsible for the insane speed of the SBS algorithm. We did this in the hope, that we soon see more VR content, from AI here or classic somewhere else.

Addional help come from some artists, namely (in alphabetic order): Robotka, schmede, VisionaryAI_Studio and z1000k. You will see the result of this tool in the many examples above and in gallery below (look into other versions, too!). Please visit and rate their original work (links included in posts), instead the of the stereoscopic variant.

The tool simplifies the process of converting images and videos to full side-by-side (FSBS). They can be viewed with VR glasses (e.g. Meta Quest or HTC Vive) or glasses on 3D Monitors.

If you publish your own converted artwork, please be so kind and add this asset under Resources in your posted videos, and tag them "VR", that makes your VR artwork easier to find. I'm looking forward to see your creations here on Civitai converted to FSBS ;-)

Our work on the asset is based on the great work of Sam Seen from ComfyUI_SSStereoscope, that gave us a good starting point in out investigations. I want also to say "thank you!" again to all the creators that gave us the opportunity to propagate the potential of this tool through their artwork.

Installation

Problems, Suggestions, Questions, Contact? Discord Support: Activation Link

Option 1: Windows Portable Package

Download the 7z file from the latest release on GitHub ; it includes Python. Execute run_cpu.bat or the nvidea ones if you have that gpu.

Option 2: ComfyUI Desktop

You need to install Python 3.12. and ComfyUI Desktop.

Other Prerequistes
Install Git Bash (for Windows) and FFmpeg.

Install ComfyUI Custom Nodes

In ComfyUI, if not already there, install the Manager. (Download "Code" ZIP and move folder into ComfyUI_windows_portable\ComfyUI\custom_nodes.

Then restart the server and you will see this icon:

First wait for the Manager to update the ComfyRegistry (watch logs).

Then use the ComfyUI Manager to install other custom node packs:

comfyui_controlnet_aux 1.1.0
ComfyUI-VideoHelperSuite 1.7.2
Bjornulf_custom_nodes 1.1.8
ComfyUI-Easy-Use 1.3.1
ComfyUI-Custom-Scripts 1.2.5
comfy-mtb 0.5.4
Stereoscopic 2.0.0
ComfyUI-Crystools 1.25.2 (optional but recommended)
ComfyUI-Florence2 1.0.5 (required for dubbing)

Then install ComfyUI-MMAudio (required for dubbing) manually:

Download from https://github.com/kijai/ComfyUI-MMAudio , then install to ComfyUI/custom_nodes folder, then execute in the bash shell:

# Locate and switch to installation folder:
cd ComfyUI_windows_portable
# Excecute install script
./python_embeded/python.exe -m pip install -r ComfyUI/custom_nodes/ComfyUI-MMAudio/requirements.txt
# create model directory
mkdir -p ComfyUI/models/mmaudio

Install ComfyUI Models

Upscale Model

Download 4x-realesrgan-x4plus manually from https://openmodeldb.info/models/4x-realesrgan-x4plus and place it at ComfyUI\models\upscale_models\RealESRGAN_x4plus.pth
Or use and configure other upscale models in config.ini

Depth Model

Test Installation

Test Workflow

After restarting ComfyUI, drop the workflow custom_nodes\comfyui_stereoscopic\examples\workflows\I2I_SBS_Converter.json into ComfyUI, select an image, e.g. custom_nodes\comfyui_stereoscopic\examples\input\Demo-Image.png and "Run". It should generate a side-by-side image.

Test ComfyUI Desktop Port Settings

For ComfyUI Desktop, the port need to be changed, since the scripts are using the default port of ComfyUI Portable. Go either to Settings->Server Config, and set the value for the port to 8188, or change the value of the property COMFYUIPORT in config.ini to the ComfyUI Desktop port (8000, look into Settings in ComfyUI Window). Sometimes when you close the window, the new instance will allocate a different port, like 8002, because the old process has not terminated.

Initialize and Test Background Task (Tool)

Using the Tool : Open a Git Bash Shell, and call the shell script:

# Locate and switch to installation folder:
cd ComfyUI_windows_portable/ComfyUI
# Excecute background task
./custom_nodes/comfyui_stereoscopic/daemon.sh

You will see the progress logged there. Check for errors and warnings. KIll the script on demand by pressing CTRL+C in the shell window.

Tool Configuration

The properties can are located at ComfyUI\user\default\comfyui_stereoscopic\config.ini

You need to restart daemon.sh after changing the configuration. You do not need to restart ComfyUI.

Tool Pipeline

To simplify things, the tool offers a video and image processing pipeline (see image below), where you just need to place files in certain folders, and pick the results up. No more need for common users to create own workflows or other CLI command and shell scripts. Batch scripts are organized in a pipeline, and transfers from scaling output to fullsbs input is automatic.

Read about the stages below to see what they are good for. The provided shell script (daemon.sh) runs in the background, waiting for the new files, then processing them and the stages automatic. See installation above, how to start.

Important:

Never place your original files there; only copies!
Do not use filenames with non alpha-numeric characters [A-Za-z0-9], especially if they come from untrustworthy sources. I do some checks but can't guarantee it is bullet proof.

Available Video Stages

scaling: Scales the video up, using a combination of upscale-model and blending with the original input. High resolution input is required by the sbs converter to produce good results. For maximum quality place them in subfolder "override" .,
fullsbs: Convert video to side-by-side (left right, full width) to be used in a viewer on your VR display.,
singleloop: Adds a reverse version of the video, so it can be looped. Useful for short videos that have no forward direction in time. I recommend to use this before dubbing.,
concat: Put multiple single loop videos together, that share the same first (and last) frame to a longer video. I recommend to use this before dubbing.,
dubbing: (Experimental) Designed to adds sound (effects) to video. Addional prompts can be added. Be aware, that this might be out-of-sync and contain strange parts. It is a tool for you to play with and quickly get some sound. Prompts are injected from ComfyUI\user\default\comfyui_stereoscopic. Use dubbing before scaling and sbs converter.
scaling: Some sites may have size limit for uploads, or your VR hardware can't handle larger resolutions and video or sound are lagging. This stage offers a 4K limiter that downscales videos.

Available Image Stages

slides: Want to see your images, maybe from vacation, in VR, but are annoyed about the way your VR viewer is displaying them? Use this to create 4K slide images (upscale + padding) as preparation to make a video.,
scaling: Scales the images up, using a combination of upscale-model and blending with the original input. High resolution input is required by the sbs converter to produce good results.,
fullsbs: Convert images to side-by-side (left right, full width) to be used in a viewer on your VR display.,
slideshow: put slides into a slide show, 6s each image including a 1s VR-compatible transition.,

Example workflows

Although not necessary to create own workflows in most cases, here are some examples.

Img2Img

A simple I2I workflow looks like this:

The sbs converter script now support images (jpg and png) as well, so you can convert and view your image library over night in VR!

Vid2Vid

For V2V an api workflow and git bash shellscript exists. To simplify usage, please create two folders under the ComfyUI/input folder: upscale_in and sbs_in
Then place mp4 files in these folders, open a Git Bash shell (under Start->Git) and change directory (with cd) to your ComfyUI folder (you can use drag and drop instead of typing).
From there you can execute the following shell scripts delivered with Stereoscopic.

Customization: Crosseye

You have to set the "switch_sides" parameter on the node (Convert to side-by-side) to true to inverse the depth. There is no such parameter in the batch scripts, but you can patch the value in the python files of course.
