With the new beta version (15.4), the import box is lacking some key pieces that would make it more useful.
1st. Be able to select sequence setting with a drop down under create sequence.
2nd. Be able to check an entire folder vs just media. And when important a folder, keep the folder structure as it is (just like importing a folder in the old version.
3rd. Bonus. When importing clips with the same audio tracks, stack those tracks in the created sequence. Maybe make that a check box. Huge request there.
Thanks for the suggestions. We are certainly looking into 1 and 2. I'm not sure I understand what you want with 3. Are you talking about syncing clips together - like in multi-cam shoots?
