AW: Why is LC text blurred on a retina display?

[Mike Bonner]

Silly question, but can  you update your archives simply by having LC
adjust the header in the file on the fly?  (Look for sorenson, if its
there, make the changes, update the archive, and then play the file)
IF its true h.264, but with just screwy header info, it'd be MUCH more
efficient to change the headers rather than a full re-encode.
