[daphna inbar] " After I have the quick time I need to give it to a client so they can make a Blu Ray of this project."
Then no reason to export to XDCAM HD. The codec is great for acquisition, but no for production.
Change the sequence codec to Prores. Rendering will be faster.
For better quality, set "Render all YUV material in high precision"
