Most mobile video editing apps are underpowered disappointments, but KineMaster is a rare exception which delivers far more than you might expect.

The app doesn’t just organise individual video clips, for example. You can have multiple layers to add unlimited handwriting, text, or layers of images and stickers, or indeed even another layered video on some hardware. There are up to four audio tracks available, and each one can contain as many clips as you need.

Precision matters, so it’s good to see that KineMaster enables frame-level video and sub-frame audio trimming, as well as including precise tuning for colours, brightness, contrast, saturation and more.

Smart effects include a surprisingly configurable chroma key, easy speed control for fast or slow motion, and there are some polished 3D transitions to explore.

An instant preview gives you a very quick idea of how your masterpiece is progressing, and when you’re happy it can be shared directly on YouTube, Facebook, Dropbox and more.

As usual with demanding Android apps, KineMaster won’t work smoothly with every device, and if your hardware is underpowered then it may be very sluggish. But you can sample the basic app for free, and overall KineMaster is one of the most capable mobile editors around, so it’s certainly worth a look.
