Doubt with BlackMagic APP on iPhone 15 pro.

When I record videos with the black magic app on my iPhone, it creates an annoying proxy file that I don't need, which consumes more storage space... does anyone know a way to deactivate this annoying proxy file that is activated by default?
To make matters worse, Davinci Resolve recognizes the original file as a Proxy... and the file that is truly a proxy recognizes me as the original.
Additionally, to download the files to my Windows PC, I have to do it via iTunes, which does not represent any problem for me... however I have only been able to save the entire folder together, it does not allow me to select the files that I want to download to me Computer, can this be configured somehow?
