Application · Video editor / Android · 2026
Multi-track video editing on your phone with transitions, titles and export up to 4K.
A video editor for Android built on Media3 Transformer, with a multi-track timeline, multi-shot layouts, animated titles and MP4 export up to 4K at 60 fps.
The timeline accepts any number of video and audio tracks plus a title track. Clips can be trimmed, split, moved between tracks and ripple-deleted, and undo and redo cover every operation.
There are speed, volume, filters, colour correction, crop, a Ken Burns effect, transitions and multi-shot layouts. The preview renders effects on the GPU with the same code as the export, and projects save themselves.
