The filesize of 40GB is very low for a DCP, your standard 90 minute film is typically over 100GB. I recall Hateful Eight being over 200GB.

If they released the actual DCP .mxf files it would be proof that the DCP was truly cracked.

I'm assuming they reencoded it to something more efficient than mjpeg2000 (no idea what the "standard" pirate codec for 4k is).

EDIT: According to another comment it's H264.

As far as I know, MXF basically contains JPEG pictures and because of that, it can't use motion prediction algorithms used in modern video codes, so the size of 40 GB for a 4K video in H.264 format is possible. But I agree that it's better to see the original decrypted container.
