yes~i think that’s the reason, because i have tried them in another Mac which is equipped with FCP, and everything is OK. Now i understand why… Thank you very much, Rafael.
Thank you for your answer, Walter. But still i have some questions. If this is an anamorphic format, then is there a way that i get a normal format? Since when I shot, I shot 16:9 videos and I don’t want to get some 4:3 video files as my result.
