It may be due to rounding when converting the timestamps to the
selected rate. mediainfo then sees that frame durations vary and says
variable frame rate. This is just a guess though.

What version are you using btw? With qtmux from git it picks 5994 as
rate, and mediainfo shows 'constant', at least with 10 frames.
