I read your post and if I understand it correctly I'm sure it can be done by modifying the code but no way with simple clicks that I am aware of. Are you into using Muvee Style Browser? Someone at Muvee most likely will respond and give you the written code but since it is the weekend it may not be for a while. I just thought I would let you know your post has not gone unseen but may be a while before you receive a reply.
Thanks for waiting for my reply. Unfortunately it is not possible to pause/mute the music by modifying the style code. As a workaround, we suggest using the trimming feature to break your music into different parts. Then add a silent track in between. Be sure to disable music cross-fading.
I have previously written about silent track to workaround other problems. If you are interested, refer to this post. You can also find the link to download the silent track from there as well.
Thanks tengchwan. The way I understand this, you are delaying audio by entering a pause. But I don't know when the magic moments appear. Do they always appear when there is no music so I enter pauses as long as the magic moments are in any part of the audio and when these parts are being found each magicmoment is being placed there? But what do I do if I want to increase the video audio's volume in magicMoments and maybe mute it altogether otherwise so the music track is not disturbed?
