There are two colours in your branding preset; Background Colour and Text Colour.
To change the Logo, tap the 'Presets' button at the top right corner of the screen and tap the preset you want to edit.
Swipe through the row of icons in the middle and select the settings you want to edit.
Tap the logo area on the right hand side to import your logo. You can import from files (such as Dropbox, Google Drive, iCloud or Onedrive), or from your mobile device's Photo Library.
Best Practice Guidelines
Logo Transparency
When importing your logo, we recommend to use a PNG image file with transparent background (alpha channel). If your logo file does not have a transparent background, then you may end up with a solid box around your logo. Using a PNG file with transparency, will mean that your logo will sit nicely over whatever background colour you have setup in the preset.
Logo shape & size
Use a version of your logo that matches the format of your video (i.e horizontal, square or vertical). For example, a very long horizontal logo will not look best on a vertical video, because it will have lots of space above and below it, and be scaled down to fit in the frame. It's common for brands to have 2-3 different versions of their logo for use in different places, for example, a 'stacked' logo and a 'long' logo. Try experimenting with different versions of your logo to get what works best for your brand and logo.
