As far as I know there is no upper limit. But I haven't tested this. I will look into it.
Can you please tell me if you were trying to make a slideshow or was it a video with just one picture?
I have found an uploaded video from another user which breaks the 6 minutes mark, but they aren't using the slideshow functionality.
Here is one which is 5 and a half minutes and they are using the slideshow function and have made it work.
Thanks for your interest,
