Comment (by vance003):

 Thanks for the reply; hopefully I can clarify. It sort of looks like
 ffmpeg used a "one size fits all" strategy for the Quicktime textual tags,
 instead of saying that "Lyrics" and "Synopsis" can be of unlimited length,
 and all the others can be no more than 255 characters. Now for the short
 tags, I don't care. I'm converting file formats for some of my sound
 files, and with valid data coming in for tags like "Album" and "Artist,"
 valid data will come out of ffmpeg. I suspect that there may exist
 somewhere programs that'll choke on the longer info in these basic tags,
 but that's not my main concern. What I'm first and foremost interested in
 is seeing if the "Lyrics" and "Synopsis" tags can be longer than 1024
