MetalPlayer is an on-device AI video player bringing real-time frame generation to iPhone and iPad. Using RIFE neural networks, it generates intermediate frames locally for smoother motion without cloud processing. Optimized for Apple Silicon, it delivers real-time 2x frame generation on newer devices and supports NAS playback (SMB, WebDAV, FTP, NFS), HDR, subtitles, and local media libraries. Built for anime fans and video enthusiasts who want a smoother mobile viewing experience.

Hi Product Hunt!
I'm the developer behind MetalPlayer.
I built this because I wanted a better video watching experience on iPhone. High refresh rate displays are amazing, but many videos are still limited by their original frame rates.
The biggest challenge was making AI frame generation work locally on mobile hardware while balancing performance, power consumption, and thermal limits.
MetalPlayer uses RIFE neural frame interpolation and Apple hardware acceleration to bring smoother motion directly on-device — no cloud processing, no uploads.
I'd love to hear your feedback:
What kind of videos would you like to see enhanced with AI frame generation?
Thanks for checking it out!

Love that it's all on-device, the RIFE integration sounds smooth. One thing that would make it perfect for me: adding variable playback speed with the frame interpolation still working correctly. Right now most players fall apart when you go above 1.5x and you get ghosting on motion scenes. Would be great to have presets or a slider that keeps the interpolation balanced at any speed, especially for slower anime cuts where motion blur matters.

Tried it on a few anime episodes and the motion is noticeably smoother without that weird soap-opera effect. RIFE on-device is honestly impressive for an iPhone.

running RIFE entirely on-device is a seriously impressive engineering choice, especially for battery and privacy on iPhones. really cool to see that kind of frame generation work without needing the cloud.
