Hi. About this question, I can share with you my experience: for this edit and for my private vision, i created the italian dub (@sidshady12 write me if you are interested to add to your edit). It’s long process (it depends how much time do you dedicate, probably in a month you can do it, i worked mostly at the weekends), but it isn’t so hard. What you need are: the audio tracks of the extended version of the movies and the list of changes and cut made by sidshady12 (you can find them here or on his website). What i did is extract the audio track of M4 Book edit and all extended movies and i opened them in Adobe Audition (i think it’s a great program to do this kind of things because you can work on audio adding effects or separate dialogue and backing music). Then i opened the movie on a video player and the original movie on another video player. Then i watched the two movies at the same time, so i can noticed when he made cuts. I suggest to you to maintain the M4 Book Edit’s track as basic track and replace only dialogues parts. Then is easy compiling a new movie edit file adding the track in your language (i used MKVToolnix) and forced subtitle track. The only parts not translated is the final Gandalf’s speech at Thorin’s funeral, that part i left it in english with subtitle. Ask me anything you want.
Hi. Do you still have the italian dub? I would be interested in checking it out (for private vision only of course), even if it’s not the updated version. Would you PM me in case you’re willing to share it?
