NVIDIA MAXINE VideoEffects SDK is an SDK for enhancing and applying filters to videos at real-time. The SDK is powered by NVIDIA graphics processing units (GPUs) with Tensor Cores, and as a result, the algorithm throughput is greatly accelerated, and latency is reduced.
The SDK has the following AI features:
- AI Green Screen, which segments and masks the background areas in a video or image.
- Background Blur, which uses the segmentation mask from the AI Green Screen filter or other sources, and produces a blur effect over the background of a video or iamge.
- Encoder Artifact Reduction, which reduces the blocky and noisy artifacts from an encoded video while preserving the details of the original video.
- Super Resolution, which upscales a video while also reducing the blocky and noisy artifacts. It can enhance the details and sharpen the output while simultaneously preserving the content. This is suitable for upscaling lossy content.
- Upscale, which is a very fast and light-weight method for upscaling an input video. It also provides a sharpening parameter to sharpen the resulting output. This feature can be optionally pipelined with the encoder artifact reduction feature to enhance the scale while reducing the video artifacts.
- Webcam Denoising, which removes noise from a webcam video while preserving the texture details.
The SDK provides several sample applications that demonstrate the features listed above in real time by using offline videos.
- AI Green Screen App, which is a sample app that demonstrates the background segmentation feature.
- VideoEffects App, which is a sample app that can invoke each of Encoder Artifact Reduction, Super Resolution or Upscale features individually.
- UpscalePipeline App, which is a sample app that pipelines the Encoder Artifact Reduction feature with the Upscale feature.
- DenoiseEffect App, which is a sample app that demonstrates the webcam denoising feature.
The input and output resolutions supported by the features of the SDK are listed below.
- The Super Resolution and Encoder Artifact Reduction features support between 90p to 1080p as input resolutions.
- Super Resolution supports the following scaling factors: 4/3x (~1.33x), 1.5x, 2x, 3x and 4x.
- The maximum output resolution for the Super Resolution feature is 2160p.
- The Upscale feature supports any input resolution, and the following scaling factors: 4/3x (~1.33x), 1.5x, 2x, 3x and 4x.
- The Webcam Denoising feature supports between 80p to 1080p as input resolutions.
- The AI Green Screen and Background Blur features require that an input image/video be at least 288 pixels high.
NVIDIA MAXINE VideoEffects SDK is distributed in the following parts:
- This open source repository that includes the SDK API and proxy linking source code, and sample applications and their dependency libraries.
- An installer hosted on NVIDIA Maxine developer page that installs the SDK DLLs, the models, and the SDK dependency libraries.
Please refer to SDK programming guide for configuring and integrating the SDK, compiling and running the sample applications. Please visit the NVIDIA MAXINE Video Effects SDK webpage for more information about the SDK.
The SDK is supported on NVIDIA GPUs that are based on the NVIDIA® Turing™ or Ampere™ architecture and have Tensor Cores.
- Windows OS supported: 64-bit Windows 10
- Microsoft Visual Studio: 2017 (MSVC15.0) or later
- CMake: v3.12 or later
- NVIDIA Graphics Driver for Windows: 455.57 or later
If you integrate an NVIDIA MAXINE SDK within your product, please follow the required branding guidelines that are available here
The open source repository includes the source code to build the sample applications, and a proxy file NVVideoEffectsProxy.cpp to enable compilation without explicitly linking against the SDK DLL.
Note: To download the models and runtime dependencies required by the features, you need to run the SDK Installer.
- In the root folder of the downloaded source code, start the CMake GUI and specify the source folder and a build folder for the binary files.
- For the source folder, ensure that the path ends in OSS.
- For the build folder, ensure that the path ends in OSS/build.
- Use CMake to configure and generate the Visual Studio solution file.
- Click Configure.
- When prompted to confirm that CMake can create the build folder, click OK.
- Select Visual Studio for the generator and x64 for the platform.
- To complete configuring the Visual Studio solution file, click Finish.
- To generate the Visual Studio Solution file, click Generate.
- Verify that the build folder contains the NvVideoEffects_SDK.sln file.
- Use Visual Studio to generate the application binary .exe file from the NvVideoEffects_SDK.sln file.
- In CMake, to open Visual Studio, click Open Project.
- In Visual Studio, select Build > Build Solution.
