The first clip I used was the 60fps 4k version of the Big Buck Bunny test footage from http://bbb3d.renderfarming.net/download.html (Standard 2d version), and imported that as-is without any problem. I then grabbed longer segments (Both 4k and HD) from our internal content repos and they just worked.
I’ll see to getting my simple demo scene zipped up and put somewhere so people can have a look at it, and write exactly what I did.
