    Thank you for the explanation, I have several video options on my camera that are totally Greek to me, this explains them all very clearly.

    Hi, is it OK if I am going to produce mostly for standard DVDs and home TV sets (family weddings for example) to shoot at 60p? or is better 60i?

      For digital output like DVD (which in turn will be used to connect to TV’s) or Internet … progressive frame rates are the way to go. 60p would be preferred over 60i since the quality should be better (e.g. no de-interlacing necessary) in theory (because you have no off-timing and twice the number of actual full frames). 60p will also allow to capture movements smoother than slower frame rates do, e.g. when panning or if subjects are moving quickly. I don’t know if that comes into play for weddings but at least you still have the option of slowing down the speed nicely for simple slo-mo which might be a desirable editing effect later. That’s how I would do it.

    If European standard is 50i and 50p why are all Blu-Ray movies on 1080/60p? Thanks.

      I am not 100% familiar with European Blu-ray disks and what the common BD format/frame rate is, however, here’s my take on it:

      50i (and derived from that 50p) stems from the old PAL era, which is/was the ANALOG broadcast standard in Europe. Interlaced had (in the analog world) just the purpose of reducing the bandwith for broadcasting. In the digital era ‘interlaced’ is a thing of the past.
      Europe is in the process of changing from PAL to DVB, Digital Video Broadcasting. So the old PAL will be a thing of the past, too, and with it 50i/50p.
      From here on only progressive (full) frames count. Depending on what you want to achieve, you choose the frame rate. Movie and broadcast content goes already into a 4k at 60p direction and so do TV sets with high refresh rates.

      As long as the Blu-ray specs, or more important, manufacturers with their BD players support 60p, AND the connection (e.g. HDMI) spec supports it, AND the connected TV set has modern, fast refresh rates can handle 60p or more, all should be ok. In the US and Europe.
