How did the studio manage to make a track with variable bit depth?
Every TrueHD track has a bitdepth of 24bit. *EVERY ONE*. Every TrueHD decoder always outputs 24bit. However, here comes the big key: Sometimes only 16bit of those 24bit are filled with real audio data and the rest is just zeroed out. With Pirates 1 most of the track had only 16bit of the 24bit filled with data, while the remaining 8bit were always zeroes. But there were a few (very few) parts of the audio track where suddenly those 8bit had data in them.

With Inside Man, if it's a 20bit track (which I don't know), the upper 20bit are filled with real data while the lower 4bit are always filled with zeroes.
