I'd love to have the ability to mute the audio for a cut rather than cutting the video. I often edit shows so my kids can watch them. There are times that I want to clip out the language but the I'm forced to have a jump in the video too. I'd rather just remove the audio.
Here is a procedure to selectively mute the volume on segments of your video:
You may find this process easier in Scene Mode where you only select the segment you wish to output. Tools>Options>General Parameters and select "Scene Mode" for Editing Mode.
Mark the first segment you would like to adjust the volume. This segment will be green with the rest of the timeline red. Adjust the volume of the segment (Tools>Adjust Audio) and add to the Joiner.
Clear the cutlist and select the next segment of the file you wish to adjust the audio level. This new segment will be green with the rest of the timeline red. Adjust the volume of the segment (Tools>Adjust Audio) and add to the Joiner.
Continue to add segments of the timeline and adjust the volume accordingly. Clear the cut list each time and indicating the next sequential segment.
Output your file from the Joiner. Joiner>Create Video From Joiner List.
