If you have a copy of the Alien Anthology, check out the extended version of Aliens. (Might be the only transfer out there, not sure.) I ran an encode at crf18 slow - it averaged under 2 fps and took over 32 hours to complete. The result? A 24GB HEVC file compared to the original 28GB AVC from the disc. Whee! By comparison, I'm running an encode with the same settings for Live and Let Die - comparable bitrate, a relatively nice transfer for a 1973 film but certainly not pin-sharp. It's averaging a little over 4 fps at the moment. edit: Now that I'm a third of the way through the file it's dropped to 3.41 fps. Still a pretty big difference from the 1.88 Aliens was getting.

Also, I did a 5 minute clip from Aliens after a reboot with no other apps open in order to rule out other PC problems. The results were consistent with the above - averaged a hair over 2 fps for crf18 slow.
