I have a new PC, when rendering to a resolution of 1998 x 1080 the video is corrupt, change the resolution to 1920x1080 or pretty much any other res it renders fine.
windows 10 Maya 2016 extension 2.
Quicktime 7.8 h.264
Nvidia 1080 drivers 411.63, Ryzen Threadripper 1920
The scene will playblast fine on the older PC with the same quicktime
