Clipjoin - Video & Audio Edit

AV Merge Master is an on-device studio for joining videos and audio, mixing tracks, recording, and playing finished clips. No account. No ads. Your media stays on this iPhone. VIDEO EDIT (main tab) Bring in several clips from Photos or Files. Reorder on a timeline, then trim, split, change speed, rotate or flip, and set volume or mute. Choose canvas size (original, 1:1, 9:16, 16:9). Add transitions and background music with volume, start offset, loop, and ducking. Preview, keep a local draft, and export MP4. AUDIO MERGE (main tab) Import audio or record into the list. Reorder, trim, split, and adjust volume, then preview and export M4A. Crossfade, BGM, fade in/out, speed, and higher bitrate are available for longer projects. Finished merges stay in a local library.
