with regard to blender, I found this article confirming that blender
is multi-thread able:
which dates to 2005!
ffmpeg's multi-thread support is more conditional:

ffmpeg -threads N -i input_video -y output_video
but this requires that the video codec that you select has
multithreading capabilities. for example in H.264 decoder you can
decode with multiple threads if the input video has slices.
