Comment (by vance003):

 Hmmm, on checking a bit more, I find that apparently ALL Quicktime textual
 metadata that is supposed to be no more than 255 characters long (like
 "Album," "Artist," etc.) can actually be encoded by ffmpeg at at this
 slightly-less-than-1024 length. That's good news if you're encoding Fiona
 Apple's second album, but it actually represents an error / defect, as it
 allows ffmpeg to produce encoded metadata that do not conform to the
 industry standard. Ultimately, however, I'm not that concerned about those
 tags --- I just want to be able to encode Lyrics and Synopses that exceed
 the 1024 limit.
