checking my own material has not been a problem, but I have been trying
to look at the fate samples. However after running 'make fate' although
the intermediate '/tests/data/vsynth1/dnxhd-1080i.mov' file exists
(which is not the one at issue),


no longer exists, only the 'tests/data/vsynth1.ref.yuv' is still there.

Given the complex nature of the make script I have not been able to work
out the command line used so I can recreate it.

Am I missing something?
