madVR

madVR is a GPU-assisted video renderer based on DirectShow that is capable of enhancing the video playback quality of various media players. With its advanced graphic image processing and scaling algorithms, it can transform regular frames into high-quality ones.

Reliable renderer for multiple players

Before using it, please make sure that your computer meets all the hardware requirements and that your player is on madVR's compatibility list. Deployment requires administrator rights.
madVR can be pointed as the video renderer of multiple players, including some of the most popular out there: Media Player Classic - Home Cinema (MPC-HC), KMPlayer, J. River Media Center, Zoom Player or PotPlayer. To begin with, set madVR as the main renderer in your player's configuration settings.
It's worth noting that the application can be set to find other network workstations that run madVR, allowing synchronized actions. To use this feature, the Windows firewall must be configured to allow it LAN access.

Upscaling and rendering tweaks

madVR comes with advanced deinterlacing and image enhancing capabilities, as well as banding artifacts removal options. It features image dithering, chroma upscaling to alter the color layer, and various image up and downscaling algorithms. Frame images can be fine-tuned by experimenting with other effects, such as sharpness, softness, anti-aliasing, and anti-ringing levels.
There are a few configuration options you can tamper with to change the rendering mode. The playback can be delayed until the render queue is filled, and Direct3D can be used on operating systems higher than Windows 7. Alternatively, video frames can be presented in advance in windowed mode.

A renderer that has a lot to offer to power users

madVR bypasses the default algorithms of your computer's graphics card in the attempt to obtain images of the highest quality possible. In other words, its primary goal is playback quality. However, there are a few settings you can change to enhance performance, with low-quality losses.
The plethora of configuration options madVR comes with and their complexity only suggest that this application is not geared towards beginners, especially since terms and options are not explained, and no documentation is available. Nevertheless, advanced users are sure to enjoy enhancing the capabilities of their video players using this powerful renderer.
