I'm working on a project in China. We shot on P2 - DVCPRO HD 720pN but we're delivering to a Chinese TV station and outputting to Beta IMX. We have to output 4:3 for Chinese television and downconvert to SD through the SDI out on our Kona LHe.
How do I get the best quality of my downconvert to SD through my Kona card. For my first output, I changed our video out setting within FCP and did not change the settings on the Kona control panel. Does this mean I'm doing a software downconvert when I should be doing a hardware downconvert with the Kona card?
Also - We are subtitling the project in the letterbox that we create from the conversion to 4:3 from 16:9. Should we adjust our sequence settings in FCP (maybe drop the HD sequence into a 4:3 PAL frame at ProRes 422 (HQ), thus allowing us to control what we put in the letterbox? Will this affect our quality substantially?
