[ID3 Dev] going past 256 char limit in comment field in iTunes

[Samuel Lago]

Many thanks! So what your saying (to be absolutely sure) is that iTunes sets
the limit of 256 chars in the comments field for media like music and video
- specifically .mov. Which means at any time in the future Apple can lift
that to allow for any length, like QT Pro does now?

Thanks.
