I get this kind of error almost every time I relink proxy files. I do not understand why PP can not just force relink the files even if there was something wrong with the audio channels. And it also does not tell me how to resolve this. So i have to recreate ALL proxy files. No matter if the existing proxies have been created on Mac or PC. When opening on a new platform there is a 80% chance of getting this error. What does it mean? What can I do? (I already tried all different options of proxy media creation.)
Sorry about that. Have you tried creating a custom proxy preset in ProRes Proxy format that carries the same number of audio channels as your original camera masters? Give that a try, and let us know if that works for you.
