Hi Mark, thank you for the feedback and the suggestion.
If it were not such a large project full of possibilities for error in the conversion for this profoundly changed new version of the program, I would try doing that. Subtitles for instance are an issue: the films footage is in different languages and I need to edit with the subtitles on top and these newer versions are also completely changed in the way the deal with subtitles. So, for all these reasons I’m going to hold off using the new Premiere Pro. The main one is the absurdly slow loading speed.
I was able to install the older 2020 version of PPro which seems to be the last one that does not have this architectural change in the media loading. On the same M1 Pro Macbook Pro it loads the project at normal speed. The 2022 seems to be completely impractical for large updated projects.
I would still love to understand why this is.
