Converting Dolby Vision Profile 7 to Profile 4

[Dalaibot]

Hi,

Sorry, I'm new to these forums , but stumbled accross this thread, where topjes talked about using MakeMKV, dovy and Mkvtoolnix to convert 4k Blu-ray rips (which are always profile 7) to profile 8 or profile 4.

Since my current setup only supports profiles 4 & 5 I've searched high and low for a method to convert my rips to Dolby Vision profile 4 and I've used all the above-mentioned tools previously, but cannot work out how to strip out the HDR10 baselayer from the BL, EL + RPU in such a way that makes the end file recognised as profile 4 by MediaInfo.

Has anyone done this before? Any help would be extremely appreciated.
