imovie 10.1.7 wont import avchd files

After starting iMovie and Importing Media from SD card reader on iMac - 'Select All' - iMovie stalls.

The progress bar shows 'Importing from...reference number .mov' but stops on clip 1.

However the clips are displayed and can be run temporarily.

the clips then go black with ? mark and 'No Camera'. I notice the SD card is formatted as FAT32 is this valid or the cause of the problem?

Up to a month ago I had no such problems for over 5 years withe same Sony camera and running Sierra on my ageing mid 2007 iMac.

I can't find anywhere in the net with a similar problem but perhaps an expert here can advise please.

Failing that I will contact apple as I am within the 90 day telephone support on the new iMac .

iMac, macOS High Sierra (10.13), iMac 21.5 4K Retina 512GB SSD

I found this in /Library/Audio/Plug-Ins/Components at the Root Level and not in the User Level. Once trashing the A52Codec.component folder, iMovie was able to import the file.

Worked for me too! I had Persian installed from way back. Removed it and now the High Sierra/IMovie combo works perfectly.

I also fixed the same problem. Only different thing was that the A52Codec.component was located at Library/Audio/Plug-ins/Components/ in my computer. Thanks.

Hey, I just saw your suggestion. I checked and did have A52Codec.component in my user's Library directory. I deleted it as you suggested and now can import from my camera again. Thank you!

Yes!!! This worked - thank you so much! I spent 2-3 hours yesterday converting .MTS files in Handbrake. This now allows me to upload the my camcorder videos back into iMovie (like before)!

It is very frustrating. Let's hope it gets fixed.
