Barry. It is already mentioned a couple of times but I never got really satisfied by the answers. When I record in 30p then the video noise is much more than the same settings in interlaced. Can you explain why that happens.

Sure, that's the nature of progressive scan. Progressive is noisier than interlaced, and always will be. The very nature of how interlaced gets scanned involves blending the lines together, which is why you get an extra stop of sensitivity and lower noise. Steve Mullen goes into a lot of detail in his whitepaper "Progressive: What You Need To Know", available here:
