user6870: I'm doing some audio deliverables for a feature film's TV package. The spec sheet I'm working from says that all media has to be provided with an MD5 checksum.
I know how to compute MD5 checksums for files but is there a specific format for checksum's that's customary?  Could I use the MD5 feature of mtree(1)? Or do you do a $FILENAME.md5 for each file? Or something else?

user14523: There is no standard used by US broadcasters for how to format checksums. I've never delivered to a broadcaster that requires it, but I've mostly been involved in delivering commercials. DPP/AS-11 doesn't specify anything about checksums and neither does Netflix. I only know of one US broadcaster that does require checksums and they require using their proprietary software to build up the delivery package.
