Same script, ffmpeg chokes while avs4x264 runs fine, both running as pipes to x264.exe.

MeGUI doesn't obfuscate anything. The command line is right in the log.
It didn't even occur to me to use ffmpeg for piping since there is a low fat pipe tool out there (avs4x264).
I can't speak for the performance difference, I have not tested it.

Can you please do this test with AVS+ 32 bit?
So I installed Avisynth+ 3.4.0 as advised by "StainleSS", and re-ran those tests...
– Quite astonishingly, running roughly the same script (I may have changed a line or two between the version used for the former tests and a reference copy I made a few hours later but nothing significant), AVSMeter gives a total time just above 47 minutes :

– Then with an updated script on which, as also advised by "StainleSS", I replaced the individual Morpheus commands by a single command pointing to a list of frames to interpolate in a separate file, it further reduced the time almost by half (although the absolute improvement from 11+ hours is less impressive it was definitely worth correcting that clumsiness), down to 28.5 minutes :

– Then I tested the updated script with Avisynth+ 64 bits, which gave only a tiny improvement, total time of about 28 minutes :

So apparently there's been a lot of progress in terms of efficiency / optimization in Avisynth / Avisynth+ over the last few years.

And the problem with Morph in 64 bits has disappeared, so it seems specific to the older version of Avisynth+ x64 I had before (last time I checked it was supposed to be up-to-date, but I myself am far from being up-to-date generally speaking, I could use a complete revision, but my mom who likes ev'rythin' to be clean and neat and tidy threw away the source code a long time ago, and I'm now way too messed up for any attempt at retro-engineering, so I guess I'll have to stick with my obsolete self until I make my escape).
