Other ways to convert mp4 to m4v?
Apple provides some documentation that describes how to get video into iBooks (http://support.apple.com/kb/HT5065) -- but this often massively increases the size of the files (4X in some cases) due to changes in the data rate of the resulting m4v file.
Are there any other tools that can do this conversion while providing additional control/flexibility of data rate / output dimensions?
I've tried handbrake, but can't find any settings / presets that iBooks will consume.
Thanks!
