I'm a new user of Hitfilm Express and really enjoy the software so far. I already successfully exported a first collection of clips. However, when I came back to the same project some time later, there were continual piano sounds on the audio track.
I know from the forum that this problem should be linked with either the activation of the software, or a non-installed audio effect. The problem is that neither applies in my case: the software is registered, and I did not apply any effects so far.
If anybody here might have an answer, that would be greatly appreciated!
