Common examples of lossy compression standards would be JPEG for images and H.264 for videos. Lossy compression typically involves discarding some of the textural information in an image as well as data encoding. These types of noises are highly dependent on the type of sensor in the camera.Įncoding artifacts in video streams are a consequence of the bandwidth constraints required to transmit frames. This is especially true in the context of end-user–generated streams, if the environment is not well lit or the camera being used is of poor quality. However, the two most common sources of noise are webcam noise and encoding artifacts.Įxamples of webcam noise sources include the camera sensor type, exposure, or illumination level. The underlying causes of video noise that make or break the end-user experience are numerous. Remove webcam video noise and reduce encoding artifacts 1: Maximum image sharpness and crispness visual effect enhancement.īy default, Upscaler’s enhancement parameter is set to 0.4.0: Increases the resolution without image enhancement.You can set Upscaler’s enhancement parameter within range: You can use this feature to scale media by 1.33x, 1.5x, 2x, 3x, and 4x. This visual effect is best used on lossless compression data such as H.264. It offers holistic enhancements while preserving the content. Super Resolution (Figure 1) generates a superior quality image with higher resolution and better textures from the provided input image. Add details and improve resolutionįor poor video quality that arises from the low resolution of the image frames, the Maxine Video Effects SDK provides two state-of-the-art AI-based visual effects: Super Resolution and Upscaler. This post demonstrates how you can run these effects with standard webcam input and easily integrate them into video conference and content creation pipelines. To solve these video quality challenges, the NVIDIA Maxine Video Effects SDK offers AI-based visual features that transform noisy, low-resolution video streams into pleasant user experiences. At the same time, these streams are the most network bandwidth-intensive part of online communication, often accompanied by noise and artifacts. The crucial part of online communication is the video stream, whether it’s a simple video call or streaming content to a broad audience. Businesses, educational institutions, and public-sector agencies are experiencing a skyrocketing demand for virtual collaboration and content creation applications. Video conferencing, audio and video streaming, and telecommunications recently exploded due to pandemic-related closures and work-from-home policies.
