I am just beginning to dabble in iClone’s Exporting Panorama Videos capability.  I have studied a couple tutorials and the iClone help manual.  The manual says “The value of the camera lens for Panorama Videos is strict. Therefore, you are not allowed to customize this value when the Exporting Panorama feature is turned on.”  Both tutorials I looked at showed frame size settings of 4096 x 2048.  This is the 2:1 ratio I need.  

However, I cannot figure out how to get these Render frame size settings. My settings won’t exceed “Ultra HD (3840 x 2160)” and of course Custom does nothing.

I am using MP4 Format and I have Windows 10 Pro 64-bit. I’m using NVIDIA GTX 980 4GB video card (latest drivers). I have the K-Lite codec pack installed. Enable 360 Panorama and 360 Enabled for YouTube and Facebook are checked.  Render Quality is set to highest settings. I have iClone 6.53.3511.1.

It’s probably some simple setting I’m missing but I’m stumped.  Any guidance would be appreciated.
