REPLAY rewraps it live
On your device, as it plays. The picture passes through untouched whenever it can.
Watch it like any other
Posters, Continue Watching, Up Next, subtitles and Clarity, on every screen.

Almost any format
MKV, AVI and the rest.
Videos Apple’s player can’t open by itself are rewrapped live on your device, so they play in Apple’s own player with everything REPLAY adds.
- The picture passes through untouched whenever it can, HDR included
- Dolby Digital and Dolby Digital Plus surround, just as they are
- The whole film is there from the first second. Jump anywhere
- Clarity, subtitles, Skip Intro and Up Next, all included

Clarity
Closer to 4K. Live.
Lower-resolution videos are cleaned up and sharpened as they play, and upscaled on devices that can, so they look and feel closer to native 4K. Your videos are never changed.
- Sharper, cleaner, as it plays
- Works in MKV, AVI and every other format
- Enhance Dialogue brings voices forward
