Giving a process more privileges than are necessary for that process
to do its function leads you to be more exposed if any security holes
can be found in that process, since the attacker self-evidently has
more privileges available.

ffmpeg doesn't require enhanced privileges, just to be able to read
its inputs and write to its outputs. Controlling access to
input/output files can be done by changing file owner or group or file
permissions, so using "sudo" solely in order to make an unreadable
input file readable is a lazy and insecure practise that inevitably
exposes you to more risks as outlined in the first paragraph.
