AVCHD video from Canon C100 stuttering in FCPX 10.4

I'm having the same issue with importing AVCHD video from a Canon C100, and it started after I upgraded to FCPX 10.4. Apple needs to look into this ASAP! Periodically the video will stutter on playback, audio is fine. I've tried transcoding the media to Prores 422, but the stuttering is still there. It only happens from the AVCHD files created on the C100.

FCPX 10.4 on a Mac Pro (Late 2013)

macOS High Sierra v. 10.13 (17A405)

3 GHz 8-Core Intel Xeon E5

32 GB 1866 MHz DDR3

AMD FirePro D700 6 GB

Work around! The trick is to get the files extracted from the folder and file structure they come in.

Load canon AVCHD Package to Hard Drive.

Right Click "Show package contents"

Search folders for BDMV package and open with "Show package contents"

You should see the clips as .MTS files**

Select the files and Option/drag the files to a new folder.

From FCPX, Import the copied files from the new folder . Use Import/media command.

Select "leave files in place" in the import window. Voila!

** If the files did not appear as .MTS, try opening the BDMV package with VLC media player.

If you don't have it, it's free online.

Once you've opened it. Quit VLC and close the package.

Start over opening the AVCHD package and follow the steps above from there.

Let me know if this works for you.

I've done it twice and it worked.

You can't run. both versions on the same computer at the same time, even in another user.

I hope you're right. I see nothing in the update notes about it so I'll wait until I get more reports of a fix. I am still on Sierra ATM but I will update as soon as I'm satisfied it works.

I found a recent project that had a workaround that was successful in it.

Somehow I had FCPX linking the clips in the Event to the original AVCHD .MTS files in the Original Media folder in the library. When I right click on the clip in the event list and open in finder it show the .MTS file

The file plays perfectly clean in FCPX

I'm not sure how I did it but I will try to replicate it a little later.

So... I see there's now a FCPX 10.4.1 update (adding closed-captions). But, not a peep about the AVCHD issue in the update notes. Kind of mind-boggling considering how widespread this problem is.

Has anyone updated to 4.1 and noticed this problem has been addressed? Or is it still a problem?

If it's still a problem, this would be a huge letdown. Considering months go by between updates, this could be an absolute nightmare for countless professionals out there.

I hope it's been quietly addressed. And as appreciative of Apple that I am, it drives me crazy that they won't even acknowledge a problem and let us know they're on it. With no updates or commentary from Apple about a problem like this, it's anyone's guess that they're even paying attention to us.
