I have an LG 3D camera and the file extension is avi.
Because it is in 3d avi, premiere pro cs6 wont import it.
Its a side by side video.
Other products like Pinnacle, Cyberlink, etc. will import it but editing and edit a title wont work.
Is premier pro ready for 3d side by side video?
Moved from the Creative Cloud to the Premiere Pro forum. They will be able to help you here.
Here are some links that discuss editing 3D material in PrPro: http://forums.adobe.com/message/3548635#3548635
I do not recall any major changes with CS 6, but there might have been a few?
