This thread hasn’t been touched in many months and perhaps everyone has already figured it out, but I thought I should put the answer here in case others stumble across it as I did:
Use PASTE ATTRIBUTES, instead of ‘paste effects”. PASTE ATTRIBUTES will bring up a box which allows you to select which attributes/effects you won’t copied.
I was pulling my hair out because I was trying to copy color grades across multiple clips, and ‘paste effects’ was wiping out all of my audio fades and levels.
Paste Attributes works!
