Video Buffer Pre vs calibratr

Record the action that happened before the shutter! Save your device storage and skip the tedious post-game editing! Never miss a moment again! Yes, it really records in 4K: up to 4K at 120 fps on recent iPhones (e.g. iPhone 17) and 4K at 60 fps on older models (e.g. iPhone 12), with your Apple Watch as a remote. We're all used to pressing the record button and capturing life as it happens. But what if you could record things that already happened, pressing the button to catch the last few seconds? That's what makes Video Buffer so unique — you set the buffer time and hit the record when something interesting happens. You haven't missed a thing and saved your time and device storage! Video Buffer can be vital in all kinds of ways: Sports coaches and parents can use the app to record in-game highlight moments as they happen. Physical Education teachers could use buffered video footage to analyze performance and settle disputes between players. Sports officials and referees can review their decisions using a Buffer Camera as a video assistant. Drivers can use Video Buffer as a Dashcam, recording unexpected events on the road without overloading device memory storage. Skateboarders can capture only good lands and save time scrolling through many similar frames on the camera roll. Parents can catch their kids playing, making it easy to record that funny interaction that might otherwise be lost. Nature lovers can save time and storage while filming astonishing lightning flashes or waiting for the animal to appear or strike a funny pose. Video Buffer features include: - buffered video recording that ensures you'll never miss a moment - long buffer time, up to 100 seconds - 3 recording buttons, each with adjustable buffer time - DualCam Mode - record front and back camera footage simultaneously - option to capture only the buffer - the recording will end & save automatically - 4K video quality: up to 4K 120 fps on recent iPhones, 4K 60 fps on older models such as iPhone 12 - custom video resolution and FPS (30-240) - portrait or landscape orientation - saving to iCloud or device folders with a custom prefix for the filenames - Apple Watch support — a remote on your wrist to make it easier than ever to hit that record button - Slow-motion support - gives sports and fitness trainers the best look at swing, ball movement, or technique. Note: Works only with some back cameras - set 240 FPS in Settings. If you've ever missed something because you couldn't hit a record in time, Video Buffer is the answer!

Your photos, the way you edited them. Out of the box, a monitor rarely shows what is in the file: too cool, too blue, with greys that drift in the shadows. Anyone who edits photos then corrects faults that are not in the picture at all. calibratr turns your iPhone into a measuring instrument for displays and makes your monitor trustworthy again. Together with the free Mac app it calibrates your monitor. The Mac shows colour patches, the iPhone measures them in RAW: no image processing, no white balance, fixed exposure. The result is an ICC colour profile for exactly that display. White point, grey balance and tone curves are corrected, and the verification patches show in ΔE how well it went. HOW IT WORKS • Open the Mac app and choose “Start calibration” • Scan the QR code on the screen with the iPhone. Both devices on the same Wi‑Fi, everything stays on the local network • Hold the iPhone a hand's width from the centre of the screen and start on the iPhone • One to ten minutes later the result is on the iPhone and the Mac: a before and after picture comparison, plus white point, gamma, contrast, gamut and grey balance WHAT THE APP DOES WITHOUT A MAC The light meter reads any glowing surface, whether monitor, lamp or window, and shows colour temperature, white point, tint, exposure and signal-to-noise. It needs only the iPhone. WHAT IT COSTS Measuring, the report and the picture comparison are free and stay free. The one-time purchase “Keep the result” unlocks installing the finished profile on the Mac: for all your displays, for good. No subscription, no account, no server. WHAT IT CANNOT DO A phone camera is not a spectroradiometer. calibratr measures white point, grey balance and tone curves repeatably; it takes the position of the primaries from the monitor's factory profile. There is no absolute luminance in cd/m². If you need a reference instrument for prepress, you need a colorimeter. REQUIREMENTS • iPhone with a RAW-capable camera, iOS 16 or later • For calibration: the free Mac app (calibratr.app.freshx.de), macOS 13 or later PRIVACY No accounts, no analytics, no advertising. Shots are reduced to readings on the device and are neither stored nor transmitted. iPhone and Mac connect directly over your Wi‑Fi.
