If you really wanted to help your editors who have TONS of older codec material

If you really wanted to help your editors who have TONS of older codec material that needs converting then you would give the option to 'convert on import' or at the very least let it be imported and then convert via Media Encoder in the same way the you have set up the proxy convertions - so it is obviously POSSIBLE and tghe idea that it's all Apple's fault for changing it is not true - Adobe you can sort this to make it more convienient. At the very lweast just suggest a no loss Codec for use in PP 2020 to which the 32 bit Mov must be converted - the best one. What you don't get is that big editing jobs are very labour intensive and any fiddling adds hours and days to the process. Personally I don't care what's under the bonnet I just need to get on with the job - so give us one simple, convienient solution.
