If you need a full multi-track video editor that can add and mix multiple interviews and overlay, and add music, a logo and captions, we recommend the following professional apps that provide all necessary functions.

LumaFusion (iOS only)

LumaFusion is the most advanced video editing app for a smartphone. It is a full multi-track video and audio editor that mimics many of the functions of desktop software like Premiere Pro, and it supports the import of branded titles and supers.

LumaFusion allows export at both 30fps/60fps (for NTSC countries) and 25fps/50fps (for PAL countries). You can also export at different aspect ratios – including square (1:1) and landscape (16:9). So you can create a version for social media and online, and a version for TV.

LumaFusion’s export settings are also designed to be compatible with desktop editing systems such as Final Cut Pro, Premiere Pro and AVID. The app is available as one-time purchase and currently costs around $US20.

The LumaFusion website has a series of introductory tutorials, and this introductory video on the LumaFusion YouTube Channel will get you started and guide you to more advanced tutorials.

KineMaster (iOS / Android)

KineMaster is a multi-track video editor for both iOS and Android, with the ability to edit both video and audio, add titles, captions and a logo. It is also possible to import branded fonts, and it can export at both NTSC and PAL settings. This makes KineMaster the most advanced video editing app for Android phones and a solid choice for iOS.

Currently it is not possible to export square (1:1) videos from KineMaster, and the free version of KineMaster has a watermark. The paid version requires a monthly subscription ($US5) or an annual subscription ($US40).

PowerDirector (Android only)

PowerDirector is a multi-track video editor with the ability to edit both video and audio, add titles, captions and a logo. It is an alternative to KineMaster.

Note: Power Director only exports at 30fps, so it’s unsuitable for TV journalism in PAL countries. The free version also has a watermark. The paid version requires a monthly subscription ($US3.99), quarterly subscription ($US8.99) or an annual subscription ($US24.99).
