Update: I also uninstalled all recent Windows updates. No difference.
Also tried renaming and deleting the following:
Did the nuclear option: uninstalled all of CC and did the Adobe CC Cleaner tool. Reinstalled.
Also installed QT. Same thing.
Sometime in the process, the error changed to:
Some import operations were not performed>Unsupported or damaged file.
I sure do love wasting hours of my life and missing deadlines. Whoo-hoo!
I was just testing .MTS files while looking for an answer for another forum question when I came across this:
Please see the following link:
As you indicated that you have "Windows 10pro N" it looks like you would need to install the Windows media feature pak as mentioned there to use the .mts files as they contain AC-3 audio.
(I can import the .mts files from 4 different cameras on LR7.4 on my Win10 laptop but not LR7.4 on Win7 desktop as a result of no built-in decoding for Win7. It works with CC2015.12 that is still installed though)
Thanks so much. It's great to finally get an answer.
But nope, that didn't work either. I am now wiping my entire system and rebuilding....
Wiped and rebuilt the OS, then S.O.S.
Anyone from Adobe out there?????????
And did the latest Lightroom cc Classic update.
Here we are, over 6 week later, and I am in customer support purgatory with Adobe. I go over the same situation over and over and over again. I have set up at least 5 times to have their "priority" team call me, and they simply do not call.
Can you upload a sample video to Dropbox or Google drive etc and then post the link?
Then myself and others can check to see if it works or fails in the same way.
