DNxHD MOV Import in Premiere CC 2018 and Transcode Media Encoder doesn't work anymore

Hello,

we have an issue on the Premiere cc 2018 and Media Encoder. DNxHD Files exported from AVID in Mov Container are not recognised anymore.

In premiere they show up just as soundfile and Media Encoder is black. Same files work fine in CC 2017 both Media Encoder and Premiere.

We tried the update but this issue is a fundemantal disadvantage. What could be the problem or don't they support this codec anymore...

I installed the CC 2018 on a mint OSX Sierra at an MacPro Late 2013. As mentioned the additional installed Media Encoder CC 2017 works fine.

Any help would be appreaciated.

Thanks,

Thomas
