Adobe Blogs has the news on this one.
Adobe has releases a set of Tablet settings for the Amazon Kindle Fire, Barnes & Noble Nook, iPad 1 and 2 and Android Tablets as well as XDCAM EX and AVC-Intra in MXF wrappers for Windows and for Mac.
And for Mac OS only they have released a set of ProRes 422 Encoding Presets.
Basically you download them and exract them, then open Adobe Media Encoder CS6 and chose Preset > Import and import the presets.
This is great, and these should have come with the program, and they need to make presets for the New iPad as well!
