راشد,
As far as I know here is the answer in brief
:As for the methods of translation
:they are
(Literal translation(word for word translation
(Free translation (meaning for meaning translation
:As for the types there are many
Written translation ترجمة تحريرية
At sight and consecutive translation ترجمة تتبعية و منظورة
Interpretation: which is instant translation, the hardest one ترجمة فورية
I think it is related to the translation of movies and so on الترجمة السمع-بصرية
