the same original video was used to create both 720p and 1080p videos.
the only reason i discovered this is because the 720p (CFR) worked on
a PlayStation 3 and the 1080p (VFR) did not (The PS3 does not support
VFR). further investigating showed that FFMPEG was selecting VFR for
the 1080p video even though the command line is exactly the same
(minus bit rate and resolution)
