Unable to import AVCHD (BMDV) movies to photos app since High Sierra update

I'm still trying to get to Apple Support on the phone and have lost the phone number and can't find it with Google. My case number is

Thanks for your efforts, Mickeyfilm. It looks like too many of us, me included, have spent too much time complaining on forums and assuming that Apple were paying attention, instead of badgering them directly. I'm a freelance professional, myself, so I can appreciate how frustrating it must be to lose a client to someone else's foul-up.

When I doubleclick the AVCHD file first I see all the files in a popup window. And then when I doubleclick a single file I see this:

No success importing files.

I can import these files using Adobe Media Encoder CC, but no audio comes in. Weird!

Thanks for the condescending response. And what is the point of anyone posting here if Apple doesn't check in? I thought they patrolled the boards. Is that only at Adobe? How do I bring this to their attention?

And it's realize.

Really annoying to see how Apple goes with every new OS release the wrong way. I think this will be the last OS update I do when this bug is solved (if not, I'll return to Sierra). Each year less features and more problems with simple things like this one.

Sorry for the rant, but it's frustrating to remember the old slogans like "it just works!" being not relevant anymore with each new OS or iOS releases.

Excerpted from the Apple Support Communities Terms of Use:

"If your Submission contains the phrase "I'm sorry for the rant, but…" you are likely in violation of this policy."

Although I had uninstalled Perian, I still found this codec in the location you mentioned. This solution worked for me, so thank you very much.

Running iMovie 10.1.8 on OS High Sierra 10.13.3 on a MacBook Pro (13-inch, Late 2011)

Perian is long gone, and I never had Flip 4 Mac. Did a NVRAM reset on my own and tried to open AVCHD.

Nothing. Same issues as before. The Photos app won't even recognize the AVCHD file to import (it is greyed out).

Mov and AVCHD are not the same. Movs are much less complex and easier to manage. It's like comparing a txt file with a docx. Yes they both contain words but one is a whole lot more complex than the other.

That is what I was referring to. My camera, by default records videos in the AVCHD format and I was having trouble importing them under High Sierra. Photo will import them from the SD card but not High Sierra Photos app.

Thanks again. The Canon showed up fine in iPhoto, along with the .mov files on the video recorder. I was able to import the files and information such as date, time, etc. were in tact. Moving them to the desktop and dragging them into Photos did not preserve the file information however, wish I could remove Photos and go back to iPhoto. Photos on the Mac was/is a mess in my opinion. Steve Jobs would not have been happy with that one.

'The operation can not be completed' I can ver the videos on the canon C100 but unable to see them on the computer or SD card or within final cut - which is what I sued to do. Unaware that software was updated.

Same issue but with AVCHD files (.mts) from a Panasonic GF1 system camera. Worked fine in Sierra but not at all in High Sierra.

Thanks ChurnetMan for the workaround and looking forward to a permanent fix!

I just tested moving my videos from my Canon T3 SD card to photos and no issue here.
