About SpeedPlayer
A precision player for practicing with your own videos, optimized for detailed replay instead of media management overhead.

SpeedPlayer is a practice-first video player built for users who want to study their own footage with precise speed control instead of managing a giant media library.
Core direction
- Load from Photos, Files, or a direct URL (MP4, MOV, M4V, HLS)
- Replay with continuous playback or a precision review mode down to 0.01x
- Push playback up to 4.00x for quick passes
- Keep A-B loop, mirror, viewport, and playback memory per video
Stage 1 product boundary
- SpeedPlayer is not a NAS browser, export studio, or AI coach in Stage 1
- The product focuses on importing quickly, resuming quickly, and refining one clip repeatedly
- Local files and playback state stay on-device by default
Supported media
SpeedPlayer supports the following formats: MP4, MOV, M4V, and HLS streams. If a video is not in one of these formats, SpeedPlayer will not import it.
