![]() The profiles are defined in mpv.conf, above. ![]() Automatic Profile Loading Based on Source Video Resolution While KrigBilateral is superior to other algorithms, if you are performance constrained on your computer, you can fall back on Mitchell without a significant impact on video quality. luma, the method of chroma-upscaling is less important. And, he evaluated quality based on SSIM, PSNR, MS-SSIM, PSNR-HVS-M and IW-SSIM measurements.įor luma-upscaling on any content other than animation, he determined that FSRCNNX is the best quality upscaler, performance-wise. He compared performance in terms of frames per second. João Vitor Chrisóstomo profiled MPV’s luma and chroma upscaling algorithms, here. It is a n implementation of the Fast Super-Resolution Convolutional Neural Network in TensorFlow, an open source machine learning platform. By contrast, FSRCNNX uses 2D convolution layers. RAVU is based on linear regression with a single layer. But, that model doesn’t have a deep architecture. In past versions of this article, I recommended using the RAVU prescaler, which is a neural network based upscaler that uses weights trained with machine learning techniques. For chroma upscaling and downscaling, I now recommend KrigBilateral. For luma downscaling, I recommend SSimDownscaler. Since I wrote the original version of this article, I have switched to FSRCNNX for luma upscaling. And, FFMPEG’s bwdif filter for motion adaptive deinterlacing is applied to interlaced video, such as live TV. On Macs, you can download and install them in your ~/.config/mpv folder.īeyond upscaling, my configuration files include optimizations for resolution, colorspace, dithering, debanding, motion interpolation, and anti-ringing. I have personally tested them on my Mac Studio running MacOS Sonoma. They are tailored to high quality rendering of traditional live TV and video disc formats. I maintain a Github repo with my recommended settings and user shaders, here. You can use HomeBrew to install MPV and MoltenVK on your Mac. Now, it is possible to use MoltenVK for significant performance gains over OpenGL. Previously, that meant that MPV had to use Apple’s deprecated OpenGL subsystem. This includes recent Windows-based PCs, Linux-based devices, and Android-based devices.Īlthough Apple devices running macOS, iOS, and tvOS prefer Metal 3, currently, there is not a Metal backend for MPV. Previously, I covered upscaling lower resolution video in my article, “ How to Upscale Lower Resolution Video to 4K“.Īs of Fall 2023, the the best graphics subsystem for the MPV media player is a combination of vo_gpu_next, libplacebo and Vulkan.
