Disable mov/mp4 caching into ram?

Hello,

Apologies if this has been covered previously but I can’t seem to find the answer. Is there an option to turn off mov and mp4 files from caching into ram please?

thank you in advance

Bumping this up if anyone has any ideas please?

Do I need to write a package to turn off caching for Mov or mp4? Seems very long winded compared to other software which just does it natively, hopefully theres a preference?
