I just exported from CS4 from my HDV timeline to a m2v/ac3 files. But, I could not get encore to work. When I look at the imported
file, the video sequence is all messed up, meaning it is not what the cs4 file is. If I import the m2v back into CS4, yep it is all messed up.
BUT, if I play the m2v in media player, it is correct.
Maybe cleaning up the Media Cache will help.
If you export a two or three minute section of the same project does it do the same thing?
I for the heck of it just did the encoding again on the 5 hour project. For whatever reason, the second time the file works. Weird!
Very weird, but at least you're up and running again.
