I've been creating screencasts lately (cut with real footage) with ActivePresenter.
ActivePresenter allows one to add "annotations" and they can be in various formats including both audio and video clips. I would like to overlay a video clip onto my screencast, but my issue is, I cannot mute or remove the audio from the video clip in ActivePresenter. When accessing the video's properties, there is a volume slider there but it is disabled.
I can remove the audio using a different tool, and then import into ActivePresenter, but I thought this would be pretty standard functionality. So, the question - is there a way to remove audio from a video annotation in ActivePresenter? The format of the video annotation is mp4 (I'll try with other various formats and see if there are formats which ActivePresenter will provide this as an option).
