I didn’t realize FCPX had an external editor function (I use it in Resolve, and it’s fantastic).

I’ve always avoided using the RX7 plugins because they lack the full functionality of the standalone version and some of them are very processor-intensive. In Resolve it’s easy to use the external editor function to roundtrip clips to RX without… Read more

In addition to all the good advice you’ve already received, there are also several easy ways to insert only the video (without audio) into a timeline in the first place, so you don’t have to remove it later.

If you disable the track destination controls on any audio tracks, the audio will have nowhere to go and won’t be added to the timeline.… Read more

For longer-term study, note that Ripple Training has an excellent tutorial on media management in FCPX; it’s not free but like most of their other tutorials it’s worth it. Their overall intro to FCPX is also excellent, as is their warp-speed editing tutorial (which might be even more useful to you as it also covers some of the basics).

John Brawley wrote a pretty insightful blog post about what he sees as “the point” of this camera: https://johnbrawley.wordpress.com/2020/07/16/it-goes-to-12k/

Lots of useful info here.

And one other thought: before you despair and decide you need a new computer, you could at least try some of these settings to improve playback:

When you say Resolve is “slow” it’s not clear whether you mean it can’t play back at full speed or whether it takes a long time for it… Read more

Following up with a quote from the Resolve 15 configuration guide, with some light editing to fix punctuation errors and typos (I just checked and it has not yet been updated for v. 16):

“The key thing to keep in mind when selecting your config is that unlike traditional editing, grading, audio post or finishing systems, imaging processing in… Read more

With Resolve, everything is about the GPU. You could have the fastest processor in the world, 600 terabytes of RAM, and lightning-fast drives and they won’t make a difference if your GPU is not up to spec. Your 4-gigabyte GPU is likely the bottleneck here.

BMD hasn’t updated their hardware configuration guide for Resolve 16 (unless they… Read more

The “Producer’s Best Friend” app might be able to do this, but it’s $100.
A free workaround that might work (I haven’t tested it) is to export your project XML from FCPX, import it in the free version of DaVinci Resolve, and then export an EDL/marker list as a text or .csv file from Resolve.

Ripple Training also has several excellent audio-post tutorials for Logic, by Mary Plummer, who now works for Blackmagic Design and wrote the manual for Fairlight in DaVinci Resolve. Speaking of Fairlight, Ripple Training also has a very good basic introductory tutorial for Fairlight that cleared up a lot of mysteries for me and opened my eyes to… Read more

I also use RX 7 Advanced, it’s awesome. A cheaper but nearly as good alternative is Acon Digital’s Acoustica editor, which has many similar tools to those in Izotope RX, including spectral repair, denoising, remixing, etc. I prefer Acoustica’s interface and end up using it for most things, and then if I’m not satisfied with the result I’ll try… Read more

There’s rudimentary background noise reduction in FCPX:

If that doesn’t do the trick there are third-party plugins.

Also see this thread on the DaVinci Resolve forum; it might be relevant if this is something that only just started happening to you:

In Resolve, try changing output gamma to 2.4 and see if that fixes it. If not try gamma 2.2

I have never experienced a crash in FCPX; maybe I’m just lucky but based on reports I’ve seen it’s very stable. Dunno about phone support; I hardly ever use phone support for any software and have called Apple exactly once since 1987.
Best advice for starting out with FCPX is to buy Ripple Training’s Final Cut Pro Core Training tutorial. The… Read more

One test you could try: in Resolve, set the timeline color space (in project settings) to Rec 709 gamma 2.2 and see if the result in the viewers is closer to what you’re seeing in Final Cut.

Okay. I’m 90% sure Resolve uses Gamma 2.4 in its timeline (and viewers) when you choose Rec 709 without specifying a gamma. I wouldn’t be surprised if FCPX is using 2.2 since if you’re using a computer’s built-in monitor you’re likely to be viewing in an office environment as opposed to a dimly lit color grading studio. Not sure about Premiere…

Brandon Li has a good free short instructional video on frame rates; I think you’ll find it useful:

To be fair, the xml for fcpx hasn’t changed in 2 years. The fact that they have a new version suggests 10.5 could be a big update.

“That is an amazingly long release note.”
Buried in it is a hint that a new version of FCPX is in the offing: if you search for the word “Final” you’ll see a note that Logic Pro X 10.5 can now correctly import Final Cut Pro X xml v. 1.9 files. But there is no version 1.9 in the wild yet: if you look at the most current version of FCPX the xml… Read more
