I have a feature length documentary that is premiering at London Film Festival in October that I am cutting on Premiere Pro- so the delivery date is very soon.
I have been working on this film (on and off) for 20 years so I have hundreds of hours of 'legacy' files. I am finding that when i try and import .mov file - it either will not allow it or it only imports the 'aiff and not the image.
Very difficult for me as I have a looming deadline in which I need to be spending all of my time on the edit and not on sorting out problems ns that Adobe Premier has created for my workflow.
I am working with an operating system - 10.13.6 and version 12.1.1 (Adobe Premiere Pro). I have also cleared all my media caches. I would appreciate a swift answer to this problem as I am being held up immeasurably.
Are the files already in the project working?
Apple is dropping support for 32 bit codecs, and Adobe made the change with PR 2018. The probable answer for you may be to revert to PR 2017. Adobe has continued support for some of the codecs, but given your timeline you can't wait to see if any others are added. I do not know if any were added with 2018.1.2, which is the latest version.
Here are a couple relevant threads:
