What is the maximum pixel width of a premiere project?

It seems that it stops at 16384 pixels width and 8192 pixels height.

I tested to create a 20000x20000 sequence but it became 16384x8192 and if i create a 10000x10000 it becomes 10000x8192.

I know of people that have done 8K ... past that I don't have a clue.

So it will be interesting what people can add, especially if we get a staffer with hard data. I'm not sure they give a hard figure in the manual/help.
