Video Delay - Replay Mirror

Video delay camera for practice: Replay Mirror shows what the camera saw a few seconds ago. Do your swing, jump or routine, then look at the screen and watch it play back — nobody has to hold the phone and nothing has to be pressed.

▶ HOW IT WORKS
• Set the delay anywhere from 0.5 to 30 seconds in half-second steps, with the slider or the + and − buttons.
• See the live and the delayed view side by side, or the delayed view on its own, larger.
• A countdown ring on the delayed view shows when the next delay window starts. Turn on the tick sound to hear it without looking.
• The screen stays on while the camera runs.
• Back or front camera. Mirror the picture if that is easier to follow — saved clips are never mirrored.

▶ PAUSE AND REPLAY
• Pause to hold the stretch the delayed view just showed: as long as your delay, up to 10 seconds.
• Scrub through it, step one frame at a time, or play it again at 0.25×, 0.5× or 1×, on a loop if you like.
• The camera keeps running while you review. Tap Back to live and the delayed view carries on.

▶ DRAW ON THE FRAME
• Add lines, angles and circles over the paused frame and drag their handles into place.
• Lines show their tilt from horizontal, angles show their degrees. Up to 8 shapes at a time.
• Handy for checking a knee bend, a club shaft, a back angle or a take-off.

▶ SAVE AND SHARE CLIPS
• Save the last few seconds or the whole paused stretch as an MP4 video clip.
• If you allow it, clips are added to your photo gallery. The app only adds — it never reads or changes your other photos and videos.
• Every clip is listed in the app with a thumbnail, its length, picture size and frame rate. Share it or delete it from there; a copy already in your gallery stays.
• Up to 300 clips. The clip list is backed up once a day (the newest 3 are kept) and can be restored.

▶ FOR ANY PRACTICE
• Golf, tennis or baseball swings, gymnastics, dance, martial arts, lifting form, jumps and throws.
• Stand the phone on a tripod or lean it against something, step back and train.
• The frame rate the camera really delivers is measured and shown, together with the picture size and the memory the delay uses.

▶ GOOD TO KNOW
• Video only: the microphone is never used, so the delayed view and saved clips have no sound.
• The picture size is picked automatically to fit your phone's memory. Short delays can run at 720p; longer delays drop to 480p or 360p. If a delay does not fit in the memory available, the app tells you the longest one that does.
• Angles are measured on the flat screen image; camera perspective is not corrected.
• The camera runs only while the Coach tab is open. Frames are kept in memory for your delay and then discarded; nothing is recorded unless you save a clip.
• There is no video player inside the app — watch saved clips in your gallery or share them.
• Portrait only.
• No account, no sign-in. Settings and the clip list stay on this device.
• Ads appear on the Clips screen and sometimes after you save a clip — never while the camera is running.
