I render mine is WMV format so it doesn't take a day to get it on YouTube. But here is where my properties are set on SV to remove NewBlueFX watermarks and keep it in HD
Template : HD 1080-24p (1920x1080, 23.976 fps)
Width : 1,920 Highth : 1,080
Frame Rate : 23.976 (IVTC Film)
Pixel Format : 32-bit floating point
Hope it helps a bit
