Download Stable/Beta Builds (Windows)

Full: full package comes pre-configured with all dependencies like FFmpeg and waifu2x-caffe.
Light: ligt package comes with only Video2X binaries and a template configuration file. The user will either have to run the setup script or install and configure dependencies themselves.

Go to the Quick Start section for usages.

Download From Mirror

In case you're unable to download the releases directly from GitHub, you can try downloading from the mirror site hosted by the author. Only releases will be updated in this directory, not nightly builds.

Download Nightly Builds (Windows)

You need to be logged into GitHub to be able to download GitHub Actions artifacts.

Nightly builds are built automatically every time a new commit is pushed to the master branch. The lates nightly build is always up-to-date with the latest version of the code, but is less stable and may contain bugs. Nightly builds are handled by GitHub's integrated CI/CD tool, GitHub Actions.

To download the latest nightly build, go to the GitHub Actions tab, enter the last run of workflow "Video2X Nightly Build, and download the artifacts generated from the run.

Docker Image

Video2X Docker images are available on Docker Hub for easy and rapid Video2X deployment on Linux and macOS. If you already have Docker installed, then only one command is needed to start upscaling a video. For more information on how to use Video2X's Docker image, please refer to the documentations.

Google Colab

You can use Video2X on Google Colab for free. Colab allows you too use a GPU on Google's Servers (Tesla K80, T4, P4, P100). Please bare in mind that Colab can only be provided for free if all users know that they shouldn't abuse it. A single free-tier tier session can last up to 12 hours. Please do not abuse the platform by creating sessions back-to-back and running upscaling 24/7. This might result in you getting banned.

Here is an example Notebook written by @Felixkruemel: Video2X_on_Colab.ipynb. This file can be used in combination of the following modified configuration file: @Felixkruemel's Video2X configuration for Google Colab.

Introduction

Video2X is a video/GIF/image upscaling software based on Waifu2X, Anime4K, SRMD and RealSR written in Python 3. It upscales videos, GIFs and images, restoring details from low-resolution inputs. Video2X also accepts GIF input to video output and video input to GIF output.

Currently, Video2X supports the following drivers (implementations of algorithms).

Waifu2X Caffe: Caffe implementation of waifu2x
Waifu2X Converter CPP: CPP implementation of waifu2x based on OpenCL and OpenCV
Waifu2X NCNN Vulkan: NCNN implementation of waifu2x based on Vulkan API
SRMD NCNN Vulkan: NCNN implementation of SRMD based on Vulkan API
RealSR NCNN Vulkan: NCNN implementation of RealSR based on Vulkan API
Anime4KCPP: CPP implementation of Anime4K

Quick Start

Prerequisites

Before running Video2X, you'll need to ensure you have installed the drivers' external dependencies such as GPU drivers.

waifu2x-caffe
- GPU mode: Nvidia graphics card driver
- cuDNN mode: Nvidia CUDA and cuDNN
Other Drivers
- GPU driver if you want to use GPU for processing

Running Video2X (GUI)

The easiest way to run Video2X is to use the full build. Extract the full release zip file and you'll get these files.

Video2X release files

Simply double click on video2x_gui.exe to launch the GUI.

Video2X GUI main tab

Then, drag the videos you wish to upscale into the window and select the appropriate output path.

Drag and drop file into Video2X GUI

Tweak the settings if you want to, then hit the start button at the bottom and the upscale will start. Now you'll just have to wait for it to complete.

Video2X started processing input files

Running Video2X (CLI)

Basic Upscale Example

This example command below uses waifu2x-caffe to enlarge the video sample-input.mp4 two double its original size.

python video2x.py -i sample-input.mp4 -o sample-output.mp4 -r 2 -d waifu2x_caffe

Advanced Upscale Example

If you would like to tweak engine-specific settings, either specify the corresponding argument after --, or edit the corresponding field in the configuration file video2x.yaml. Command line arguments will overwrite default values in the config file.

This example below adds enables TTA for waifu2x-caffe.

python video2x.py -i sample-input.mp4 -o sample-output.mp4 -r 2 -d waifu2x_caffe -- --tta 1

To see a help page for driver-specific settings, use -d to select the driver and append -- --help as demonstrated below. This will print all driver-specific settings and descriptions.

python video2x.py -d waifu2x_caffe -- --help

Running Video2X (Docker)

Video2X can be deployed via Docker. The following command upscales the video sample_input.mp4 two times with Waifu2X NCNN Vulkan and outputs the upscaled video to sample_output.mp4. For more details on Video2X Docker image usages, please refer to the documentations.

docker run --rm -it --gpus all -v /dev/dri:/dev/dri -v $PWD:/host k4yt3x/video2x:4.6.0 -d waifu2x_ncnn_vulkan -r 2 -i sample_input.mp4 -o sample_output.mp4

Upscaling taking too long

Hi! Im trying to upscale a video using video2x. running this: - python3 video2x-4.7.0/src/video2x.py -i ./test.mp4 -o ./upsized.mp4 -d realsr_ncnn_vulkan -h 512 -w 512 it says it will take aprox 26 hours to run.

its a 24 second long video 60 frame video, is this normal?.

Im running it on WSL, Ubuntu 22.04.1 LTS. Python -V : 3.10.6

These are my pc specs: GPU: Nvidia geforce RTX 3070 8GB VRAM Processor Intel(R) Core(TM) i9-10900KF CPU @ 3.70GHz 3.70 GHz Installed RAM 16.0 GB DDR4

I dont know if its taking full advantage of my graphics card, because i saw the GPU Cuda tab on the task manager very low. The CPU in the other hand was at 99% for the 2 hours i let the thing run, i cancelled because i thought 26 hours was just to long to have my computer make the upscaling...

Could you help me with this please?.

Regards

Can't I make a video with the backed up dump folder?

I did upscaling for the first time. I waited 17 hours and when I checked the final result, there was a problem. When I tried again, I had to wait another 17 hours.

I backed up all 71GB of upscale images before the Tump folder was deleted. Can't I make a video with the image I backed up? The original video is 8 minutes and 5 seconds long.

Please help me .

5.0.0-beta-6 is working, but I'm getting awful fps.

After tinkering with this thing for hours, getting docker and nvidia-docker2 set up, the thing finally appears to be running, with the following command:

sudo docker run -it --rm --privileged --gpus='all,"capabilities=compute,utility,graphics,display"' --env DISPLAY:$DISPLAY -v $PWD:/host ghcr.io/k4yt3x/video2x:5.0.0-beta6 -i input.mp4 -o output.mp4 -p1 upscale -h 720 -a waifu2x -n3

...but I'm getting a lousy frame rate, like between .17 and .56 fps. My laptop's 3070 is not engaging at all.

Google Collab - "Expected Output File Does Not Exist"

Hi, I'm trying to use the provided Google Collab page to upscale a video. All the steps on the website are working fine, except the very last one which gives the "Expected output file does not exist" error ( see attached image).

I'm not a programmer so if anyone can give advice on how to fix this issue, I would be very grateful.

⚠️ Known Issues

Warning: Some users have reported that the software did not make it clear that the cache folder will be deleted after the upscale is completed. If you want to use a custom cache folder, make sure to use a designated folder with no other contents in it as the cache folder will be wiped after upscaling is done. A warning will be added into the GUI in the upcoming version.

Update

The light version has been taken off since some upstream changes broke the setup script.

Removed the use of shlex.join and := to make the program compatible with Python 3.6 and higher

Updated UI design for better visibility of the preview image

Redesigned logging system and error reporting system

Logs can now be saved optionally when the program runs into an error

If unspecified, logs will be deleted automatically upon normal exit of the program

Logs are now written to a tempfile.TemporaryFile object by default instead of a conventional log file

Various other improvements and code optimizations

Bug Fixes

Fixed waifu2x-caffe output quality option

Fixed Gifski output resolution issues

Other Notes

waifu2x-caffe has recently upgraded their CUDA Toolkit (11.0) and cuDNN (8.0.3) versions. This makes it incompatible with some of NVIDIA's older models of GPUs

To run the newest waifu2x-caffe (version 1.2.0.4 at the time of writing this note), your GPU must have a Compute Capability >= 3.5

Check this link for a list of NVIDIA's GPUs and their Compute Capabilities
