Video Looper: AB Repeat Player

Video Looper is an A–B repeat player for practicing one part of a video: set A and B around the step, riff or swing you are learning, slow it down and loop it until it sits. Loop Studio can also turn that part into a repeat, boomerang or reverse video to save or share. ▶ LOOP THE PART YOU NEED • Drag the A and B handles on the thumbnail strip, or play and tap Set A here / Set B here. • Step one frame back or forward. The arrows use the clip's real frame times, so A and B land on a frame. If those times can't be read, the arrows step 1/30 s and the screen says so. • Repeat the section ×1, ×3, ×5, ×10 or until you stop. A ring shows how many passes are done. • Pause between repeats: none, 0.5, 1, 2 or 3 seconds, to get back into position. ▶ SLOW IT DOWN • Playback speed from 0.25× to 2× in seven steps. • Preserve audio pitch tries to keep the original pitch when the speed changes. • Speed trainer: after each repeat the speed rises by 0.05× until 1×. • Mirror the picture for dance practice and pinch to zoom up to 4×. • Full screen, with the phone turned sideways if you like. • Save the frame on screen as a picture in Photos. ▶ SAVED SECTIONS • Name a section (Intro, Turn, Bar 12) and open it again in one tap from the library. • Play the saved sections of a clip one after another. • The library lists your videos with file name, length, date added and their sections. Favorites stay at the top. • Back up your sections to a small file and restore them later. Before anything changes, the restore shows how many are new, already here or deleted earlier. ▶ MAKE A LOOP VIDEO • Repeat: the section several times in a row, up to 10. • Boomerang: forward, then backward, up to 10 times. • Reverse: the section played backward once. • Speed from 0.25× to 2× built into the video. Size 480p, 720p or 1080p, never above the original. • Preview first, then export an MP4 with no watermark and save it to Photos or share it. ▶ GOOD TO KNOW • A loop video can be up to 60 seconds long, and a section up to 3 minutes. Boomerang and Reverse work on up to 900 frames (30 seconds of a 30 fps clip). • Sound: Repeat keeps the sound at normal speed (1×) when the clip's sound can be copied. Other speeds, Boomerang and Reverse make silent videos. Preserve audio pitch is for playback. • Mirror and zoom are for playback in the app. Exported videos are not mirrored, and full screen shows the plain picture. • A video you add is copied into the app, so it uses storage. Removing it from the library deletes that copy; the original in your gallery stays. Backups hold your sections, not the videos. • No camera and no microphone. Loop Studio only adds the videos and frames you save to Photos. • Your library and sections stay on your phone. No sign-up. • Ads appear on the library screen, when the app opens and sometimes after you save or share a video. Not during playback and not while a video is being made.

On the "Make" tab, from the second video you save or share since the app was started, a full-screen ad can appear a moment after "Save to Photos" finishes; before, it only came after "Done". The first video still shows no ad, touching the screen, switching tabs or going back right after saving cancels it, and after "Share" it can only appear when you tap "Done".
