Is someone here knowledgeable about .bik file? In short, my problem is this: i have a .bik file whith several audio tracks. I wanted to reduce its size by "binking" it again and setting the data rate to 80% of the original. Problem is, the new .bik file loses all audio tracks which the original had: in fact, when the conversion begins, a warning message "No sound found in the bik file" appears, even though there are audio tracks. What do i have to do in order to make the software recognize them? I have also attached the settings i'm currently using.
Here is a screenshot of the original bik file info:
