OnKino: XREAL 3D Player

OnKino turns your iPhone into a remote control and a video player for XREAL One and One Pro. Plug the glasses in and the app picks them up on its own.

SCREEN
Pin the screen to a spot in the room, let it follow your head, or stretch it out wide. You set the size in inches and the distance in metres, and the limits come from the glasses themselves. If the screen wanders off, one tap brings it back in front of you; if it sits at an angle, a separate button levels it with the horizon. You also get a stabiliser, a Side View mode and a depth control that shifts the left and right images apart, so the screen feels nearer or further away.

The app does not just write settings to the glasses, it reads them back – so anything you change with the button on the glasses shows up on the phone too.

PICTURE
Brightness, three levels of lens dimming, and colour temperature in kelvin rather than as step 5 of 9. Vivid and natural modes. Five levels of text sharpness. As you adjust the colour or the sharpness, the glasses show a test pattern and you can see the difference straight away.

DEPTH
The app works out how the left and right images are laid out in the frame – 2D, Half SBS, Full SBS or Over-Under – and you can correct it by hand. When a 3D file starts, the app switches the glasses into their own 3D mode and switches it off again when the video ends. In wide mode the panel runs at 3840 pixels across, so each eye gets a full 1920. Spatial video shot on an iPhone plays in 3D as well.

SCENES
A scene is one tap instead of six settings: screen mode, size, distance, stabiliser, brightness and dimming. Six come ready-made, and you can save your own from however the glasses are set at that moment. You can apply a scene in the middle of playback. If the glasses refuse a setting, the app says so rather than pretending it went through.

VIDEO
Formats: MP4, M4V and MOV, with H.264 and HEVC video and AAC, AC-3, E-AC-3 and ALAC sound.

Copy a file over a cable, send it by AirDrop or drop it into the Files app, and it appears by itself – there is nothing to import. Video shot on this iPhone plays straight from Photos, with no second copy left on the phone. SMB shares and direct links work too, m3u8 playlists included.

While you watch, you can choose the audio track and the subtitles, set the subtitle size and put a backing panel behind them, skip thirty seconds or five minutes at a time, and pick up where you left off. The lock screen shows the title with a still from the video, and your headphones can pause it. A call or an alarm pauses the video, and playback carries on afterwards. The phone will not go to sleep while a video is running, so it can sit in your pocket. You can send the sound to a speaker or to headphones and leave the picture in the glasses. And if the glasses are not to hand, the phone itself becomes the screen.

BUTTONS ON THE GLASSES
From the phone, you can assign any of the glasses' own functions to a short press, a double press or a long one. While
