How to best edit audio across multiple clips

Hi. I apologize if this has already been asked. I searched before posting but didn't find an answer.

I'm currently using the trial version of FCP to see if I want to switch from DaVinci Resolve Studio, which I've been using since version 14. I like DR, but I'm always looking for options and ways to speed up my workflow.

Motion seems a LOT better than Fusion for animations and FX.

FCP has some features that I really like...but then it's time to edit the audio.

I know it doesn't have track-based editing, but is the only option to copy & paste settings between clips? Is there any way to do automatic sound ducking?

I have have Logic Pro and saw that audio can be exported and finished there, but there's not a lot of info about actually doing it. My guess is most people do everything inside FCP. Does anyone here do that? How does it work for you?

I know my question is sort of vague, but I'd love to hear how others edit their audio. Thanks!

Yeah, you're asking about the weakest aspect of FCP. It really lacks badly in the audio finishing department.

Round-tripping to Logic is OK (not great) and only reliable with small projects. Simply export an XML from Final Cut, open that in Logic. To go from Logic back the FCP, read this.

Note that it'll make a whole new set of audio files. It's not elegant, and I try to avoid this round trip as much as possible.

No automatic ducking, lack of Roles based audio tools prevents that.

Apple filed for a patent for a Roles based mixer years ago, but we've yet to see it, and it is very, very, very sorely needed. If we don't get pro audio mixing/mastering tools in the next six months, I'm seriously considering moving over to Resolve permanently. I've put up with a crippled NLE for way too long.

You can put everything in your Project's timeline into a Compound Clip, then expand the Roles (using the Timeline Index) and apply filters and keyframe levels there, but then you lose your ability to tweak video edits. To do that you have to go back inside of the Compound and tweak them, and you lose your audio work until you back out to the Compound timeline again. It's a really horrible excuse for a work-around of something there's no reason to already have the proper professional tools to do in the first place.

I personally would never auto duck but if you like to do it in FCP you could use  www.pro-tools-expert.com/production-expe...is-great-new-plug-in . Haven’t tried the plug-in myself.
And yes the only way to get a bunch of  clips doing the same is to copy paste or combine them in a Compound.
funny how people can be diff as I never missed a mixer in FCPx as I always work audio clip based. It’s more intuitive that any adjustment stay with the clip and not depend on that clip being in ‘a track’. I see that it maybe causes here and there a little more work but if I need to adjust one individual say interview clip I never have to worry how that will affect ‘the whole track’. 

Thank you, Ben. I will experiment more with doing a compound clip. I had to make a video that was CALM compliant and found that I had to put it into a compound clip and then add the multimeter plug-in to that. It might not be a bad way to work, but it's different than I'm used to doing.

It's interesting because I always edit each clip manually to fix any issues where someone may have spoken too loudly or there's some background noise that needs to be reduced, so adjusting EQ and other settings on one clip and then pasting the settings to many wouldn't be unreasonable. It's just a different workflow than I'm using to.

As for automatic audio ducking, that's not something I do often, but it works okay for YouTube videos with music in the background. If the video is something like an advertisement or for someone making a presentation to a potential client to show what their company offers, those need to be perfect. I wouldn't trust it being done automatically.

I edit clips in groups on a daily basis, and single-clip-only takes up a tremendous amount of extra time. Compound Clips have huge drawbacks to this.

And if I had an auto-duck feature (that was affordable) I'd be using it daily for TV broadcast work. I use other apps that do auto-ducking and I for one miss it like crazy from legacy FCP. I could readjust edits and my ducking would be automatically readjusted. And it was perfect.

Copy/Past-Attributes is nice, but when you have a change in your edit, and then need to change a single setting to a single effect on all those clips, you're in for a world of wasted time.
