Comment:

 For future tickets: Please always provide the command line together with
 complete, uncut console output.

 I can confirm that the following command line does not execute faster than
 without -skip_frame nokey and takes nearly as long as ffmpeg -i
 Vertical400kbit.sorenson3.mov -f null - (while ffmpeg -skip_frame nokey is
 significantly faster).
