I use final cut to edit videos. Two things I haven't figured out how to do is to automatically that I would love an automatic solution to:

1. Cross fade the audio between clips, without crossfading the video, if the sound is available past the cut point. I think its pretty much 90% of the time that I would want something like that.

2. I have clips from a gopro that had a selfie stick that made a loud clicky sound from rattling that peaks above regular audio. Some way to lower the volume on that clicky noise without having to manually go through and do it for each click.
