The application offers an optional in-app subscription called Frame Rate Conversion (FRC or HFR or MEMC), which provides enhanced video processing features. This subscription is paid and becomes available after a short trial period, allowing users to access advanced frame rate conversion capabilities. All other functionalities of the app, including the ability to play MKV files and other formats, are available for free, ensuring users can enjoy core features without any cost.
The app utilizes the SmoothVideo Project (SVP) real-time motion interpolation engine, also known as MEMC. This engine allows users to select target frame rates such as 48 fps, 60 fps, or even 120 fps (depending on hardware support), plus options for x2 and x3 rate conversions. The application also offers flexible configuration options and features black bar detection and lighting adjustments for an improved viewing experience. Additionally, it includes a built-in file browser that supports streaming from various sources like WebDAV, FTP, SMB, DLNA, Emby Server, and Plex Server, making media management effortless.
One of the notable features is the app’s ability to stream videos interpolated with the RIFE neural network directly from a desktop PC running SVP 4. This integration enables sophisticated motion enhancement for smoother playback on supported devices. However, users should be aware that the SVP engine demands a recent and powerful CPU—equivalent to at least Apple A13 or higher—for optimal 1080p video playback with frame rate conversion enabled. The app is resource-intensive and may significantly drain the device’s battery, especially on older or less powerful hardware. The developers advise against leaving negative reviews based solely on device capabilities.
Built upon the mpv video player framework, the application supports a wide range of video and audio formats, hardware decoding, network streaming, and advanced rendering features. It includes options for high-quality scaling, adaptive frame rate (AFR), HDR tone mapping, audio normalization, and direct access to mpv configuration files for advanced users. For more information and desktop applications related to the app, users are encouraged to visit the developer’s website. It’s important to note that 120 fps support depends on the device hardware and iOS version, and users must agree to the End User License Agreement provided by Apple.
