Started recording too late again? Minus5 already has it. While the camera is open, Minus5 keeps the last seconds of video. When something happens, tap after the fact: the clip starts before your tap and keeps recording a few seconds after it. Everything you didn't mark is overwritten, so a whole match leaves only the clips you tapped. HOW IT WORKS • Point the camera and watch the game, the skate park or your cat. • Tap the event's button once it has happened. The seconds before are already in the clip. • Every clip is saved with the name of its event: GOAL, KICKFLIP, LIGHTNING or a name of your own. HIGHLIGHT REEL Clips come together in a project: a soccer or basketball game, a sparring session, a skate ride or a collection. They line up in the order they were shot, each with its match time and score. On goal clips, tap +1 for the team that scored, and the rest pick up the score. If you started filming after kickoff or a goal didn't make it into a clip, set the score before the clip by hand. Project graphics sit on the video like a broadcast: a scoreboard, team names, match time, a title and the date. Five styles, each block placed where you want it. Export with the graphics or without. One clip with graphics exports for free. The whole project in one video, every highlight of the match or only the goals, takes Minus5 Pro. Pro also lets you turn off the logo at the end. Minus5 stays free. Buy Pro once to keep it forever, or subscribe monthly. EVENT BUTTONS • Ready-made presets: soccer, basketball, combat sports, skate, pets and street • Your own buttons with a name, icon and color • Two moments back to back both save in full • Tap again during the countdown for 5 more seconds • MAX pulls everything the camera still has into one clip • Seconds before and after the tap, set per button (up to 60 and 30) REC THAT REACHES BACK • REC starts up to 90 seconds in the past and records until you stop it • Start and stop it with the volume buttons or a Bluetooth camera remote, without looking at the screen CAMERA • 720p, 1080p or 4K at 30 or 60 fps • Zoom across the lenses; zoom and exposure on Camera Control • Stabilization: off, standard or cinematic • 1080p at 30 fps lasts a whole match SHARING • Export to Photos with the event badge and the logo at the end • Trim the clip, rotate it or change its event before export • Crop: zoom in on the moment up to 3×, and only that part of the frame goes into the video • Replay: a moment from the clip plays again right after, up to 4× slower • The original clip stays untouched and keeps its real capture date Help and questions: support@minus5app.com, https://minus5app.com/support Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
