 Replying to [comment:2 dericed]:
 > So perhaps this means that the interlacement metadata is not passing
 through the movie filter.

 That was my guess but I don't know much about the internals of this
 filter.

 > The reason I was using the movie filter is that I was hoping to generate
 one command to gather both info from idet about interlacement as well as
 info about what the codec/container says about interlacement to identify
 conflicts.

 Thank you for explaining this!
