I haven't had access to the media that would let me test it with 14.5. The safest bet is to install Premiere CC and Media Encoder 2018 for a project that uses that media. If you want/need to work in the latest version, you can use 2018 to transcode it into the uncompressed format of your choice. The shop where I work (a community college) can't afford to replace their P2 cameras, so I'm kind of stuck with the situation.
Same thing here. Even in prelude. I have tried all different 14 versions, and it is the same. Installed v13 and it works. So I have to load v13 and ingest / import the P2 files, and then start v 14, import the v13 project and work from there... Hope this can be fixed. Running MacOS Catalina.
