The HD-SDI output is 4:2:2 sampling and so is the HDMI output. I talked to Sony representative and they explained that the HD-SDI outputs the highest quality possible from the camera, however if you are shooting anything other than 60i, it goes through a 3:2 pulldown that must be removed in post. There is no loss of quality when doing this, it’s still the 24p or 30p footage just hidden in a 60i stream since that is all that can be sent through HD-SDI. I hope this answered your question.

I had a talk with the Sony technicians and they explained to me that on the NX5U only 1080/60i can be sent out. So if your using the 1080/24p it is converted into a 1080/60i stream when sent through the HD-SDI jack using 2:3 pulldown. You have to capture it as 1080/60i then use a reverse telecine to remove the 2:3 pulldown. Some capture cards have automatic 2:3 pulldown removal and can do this on the fly and I know the NanoFlash SDI is suppose to have automatic pull down removal so you can capture 24p. In essence you are capturing 24p in every method it’s just disguised in a 60i signal. I hope this made sense and is some help.
