Nik’s Playback App is a photo and video player for iOS and Android. Created for the film & television industry for occasions when a phone or tablet needs to ‘perform’ on camera, it may be useful to anyone who wants to use their device screen as a highly customizable, flexible and remotely controllable display.

  • Build playlists from locally stored photos and videos

  • Assignable hotkeys for a remote Bluetooth keyboard

  • User-defined unlock code to unlock the display during playback

  • Proximity sensor support to simulate a phone call

  • Support for on-device camera with working photo and video recording

  • Image adjustments, including brightness, contrast, saturation, and numeric colour temperature correction

  • Stretch, scale and reposition any image or video

  • Save and load playlists

  • Generate a chroma green, blue or any single-colour screen screen sized to the device display, with or without tracking marks to assist screen replacement in postproduction

  • When first launched, the device will prompt you to create an unlock code. During playback, touching the same four corner regions of the screen in the same order as the unlock code will return you to the home screen.

  • Use the menu in the top-right corner to change the unlock code, assign your own keyboard hotkeys, launch an editor for image settings, geometry, or playback speed, or design a coloured screen or camera viewer.

  • The icons in the top-right corner of the display will allow you to adjust the system brightness and device orientation. The orientation you choose will remain locked during playback. On Android, you must enable ‘auto-rotate’ in settings to use the reverse portrait orientation, but the orientation of the app will nevertheless remain fixed. On iOS, it’s recommended to lock the device in portrait mode if you’re using the camera feature in order to avoid distortions in the camera preview, but the app’s orientation will remain

  • The collection of six icons on the bottom-right represent the most common playlist options. Tap the gear icon to see a full-screen view of these toggles with text explanation.

  • The check mark below the icons will turn blue if and only if the displayed settings are applied to the entire playlist, or to all the playlist items currently highlighted.

  • To change some but not all of the settings associated with items in the playlist, tap the items you wish to change to highlight them, then change settings in the icon panel to the desired configuration, and finally apply those settings by tapping the check mark, verifying that it has turned blue. These settings are now applied only to the highlighted files.

  • At the moment, only one camera is allowed in a playlist at a time.

  • Due to a known bug, you may experience the following: After typing in a name for a saved playlist, an on-screen keyboard may appear during playback when you use a hotkey command. Restarting the app should clear this issue, and changing your device’s software keyboard to a third-party version may prevent it altogether.

  • When using the camera on iOS, rotating the device may cause the camera feed to become distorted. It’s recommended to lock the device in portrait mode if this occurs. The app itself is locked in portrait mode in order to avoid unintended orientation changes, and handles all image rotation internally.

  • When iOS devices take a photo, they play a ‘shutter’ sound effect even when the volume is off. This is not a bug, but may present a problem during filming. Video recording can be accomplished silently.
