Dear mr. Carl,
the ffmpeg exe that is fast is the following

Please consider that I tested many ffmpeg version released in 2023 and
2024 and they all were slow.

The ffmpeg.exe I use is an executable of 108.45 GB, filedate 25 Oct
2021, ant it does the job at 65-70 frames per second, pretty fast.
But if I replace the ffmpeg.exe file with a more recent one,
including the one released a few days ago (137.53 MB, filedate 30 Dec
2024), the speed goes down to 25-30 fps.
Please always include the command output so we can see which
version/build/etc you're running- it'll start with something like this:
ffmpeg version 6.1.1-full_build-www.gyan.dev Copyright (c) 2000-2023
the FFmpeg developers
built with gcc 12.2.0 (Rev10, Built by MSYS2 project)
[...]
(that's quite old)
