Hi everyone, 

I'm about rendering a Prores 422HQ 25fps upper field first file for broadcast TV. Should I set the bpc to 8 or 16? 8bpc is ticked by default. Should o change it? Which will pass QC?

I used to always say the 8bpc is fine. But in some intense testing by @Jarle Leirpoll he found that indeed, setting the 16bpc switch is wise in both seqeunce settings and in exports for many things ... especially 'upper' Q DNx and ProRes formats.

 

So ... probably the 16bpc option is at least safest if not wise or (quite possibly) necessary.
