Disney Makes Creative Use of Seamless Branching / Multi-angle
It seems that Disney joins other Blu-ray studios making use of seamless branching in their Ratatouille released last week. Apparently they are using the feature to allow for multiple language support in video.
So when you are watching Ratatouille in English, you see one branch with English text on screen – if you select Spanish or French you are taken down a different branches respectively, displaying the text in your chosen language.
Studios have used this technique in conjunction with the ‘multi-angle’ feature on DVDs. It is great to see this being used for HD presentations also.
