New version 1.1 → 1.2

• Lens switching On devices with more than one back camera, you can now switch between lenses such as 0.5×, 1× and 3×. The lens, zoom factor and field of view are saved with each video and shown in the player's capture info. • Fixed frame rate and resolution Frame rate (240/120/60/30 fps) and resolution are now separate settings. The frame rate you choose stays the same regardless of shutter speed or lighting, including while recording. • Shutter speed improvements The shutter speed you choose no longer changes on its own when you rotate the device or the camera is interrupted. The slowest selectable shutter speed is 1/fps. • Auto-hiding controls After 5 seconds without use, the control panel collapses to a small record button so you can see more of the scene. You can also hide it by tapping an empty area of the panel. • Settings remembered Shutter speed, frame rate, resolution, exposure compensation and lens are now kept the next time you open the app. • Other Improved stability.

About

For physical education, sports coaching, and biomechanics research. Shoot high-speed video and review it frame by frame—all on your iPhone or iPad.Motion Camera supports high-speed video capture for motion analysis using the camera on your iPhone or iPad. Choose a shutter speed, and the app automatically adjusts the rest of the camera settings around it. You can also review your recordings frame by frame—including videos shot with other cameras that are saved in Photos. KEY FEATURES • Shutter-priority capture: ISO and frame rate are set automatically • Exposure compensation • Level showing left–right tilt and the forward–backward tilt of the optical axis • Step 1 or 5 frames at a time, or jump to the first or last frame • Set In and Out points and see the frame count and duration between them • Pinch to zoom • Slow playback (1/2 to 1/8 speed) • Capture settings (shutter speed, ISO, and more) are saved with each video and shown during playback • Slow-motion videos from Photos are loaded as the original high-frame-rate file, so every frame is evenly spaced The maximum frame rate depends on your device.
