I have some Whatapps voice notes that I would like to add videos to and then upload to YouTube. Please tell me how to do this. I am a newbie.
Whatapp voice notes are in the Opus/OGG format. Hitfilm cannot read OGG, so you'll have to use a third party app to convert to mp3 or WAV first.

Once the audio is converted you can load the file into Hitfilm and edit away.
