Alight Motion is not a video editing app, so you would need to edit your video in another app – like VN or LumaFusion.
Alight is a post-production app, (similar in approach to Adobe After Effects if you work on a desktop). Alight gives you a huge amount of control over titles, captions, logo and other objects – both in terms of the styles and fonts available, and in your ability to animate these objects on the screen. You can even import branded fonts.
LumaFusion is a professional video editing app that has the functions of desktop software like Premiere Pro and Final Cut Pro X. As well as comprehensive multi-track editing, you can add titles, captions, and a semi-transparent logo, or even import and layer an animated HEVC file with alpha, without leaving the app.
Here is a detailed reference guide to get you started.
It’s also possible to import branded fonts into LumaFusion. Here is a reference guide article explaining how to do this.
KineMaster is more than a video editing app. It allows you to add titles, captions and a logo. The app requires payment to remove the watermark.
PowerDirector also allows you to add titles, captions and a logo without leaving the app. PowerDirector also supports custom fonts.Here’s a tutorial explaining how to add custom fonts in PowerDirector:
OTHER APPS FOR ADDING CAPTIONS AND TITLES
If you are editing in an app that doesn’t support captions and titles – like iMovie – or you want to try some new text effects – here are some apps that only do text-on-video. You would import your video into these apps in order to use them.
Vont (iOS / Android): Vont is an iOS-only app for adding titles and captions to videos. It allows you to import branded fonts and has a great cropping tool to turn landscape videos into square versions, with a branded-colour background.
AUTOMATIC SUBTITLING APPS
There have been huge advances in the past couple years in speech-to-text recognition in smartphone apps. These apps will recognise human speech and turn it into text, which you can use for subtitles. Some apps are English-only, while others work in multiple languages.
Autocap (iOS / Android): An automatic speech-recognition app that will caption videos in landscape, square and portrait on Android phones. You talk to the app, it transcribes your voice – and you can edit before posting. Here is a tutorial to help you get started.
MixCaptions (iOS / Android) uses voice recognition to transcribe your video and turn the text into editable captions. It can recognise 23 languages. The app is relatively expensive at $US24 a month but there is a free trial so you can try it out before purchasing. Here’s a tutorial to get you started.
AI Subtitle (iOS): This relatively inexpensive app does what it promises: it uses AI technology to turn speech into live captions in your video. It supports multiple languages.
