    50P/60P Shutter Angle Question

    I have a couple of questions regarding shutter angle when using 50p (I live in PAL land but questions relevant to 60p too). 1. If you're going to conform 50fps to 25fps for slow motion, isn't it best to shoot at 1/50th shutter speed (360 degree) in order to retain a 180 shutter angle once the footage is conformed? I think most stuff I've read seems to suggest shooting at 100th sec in 50p even for slow mo. Why? Just to be clear I'm not talking about using twixtor etc. I'm sure this has been discussed before elsewhere, but I can't find anything clear from a quick search. 2. My D5300 shoots 50P at a bit rate of about 37mbps, whereas in 24P it shoots at about 23mbps. So I'm wondering - why don't I shoot 50P at a 360-degree shutter angle (50th sec) and benefit from both the high-bitrate (more detail, less macroblocking, etc) and the look of 25fps motion blur. I might be missing something about the significance/function of shutter angle here, but right now I can't think why this wouldn't work. Just to be clear, I'm not talking about conforming 50p here - this question is about real-time footage.
  2. My first slow motion for Nikon Italy with new Nikon D5300:

[color=#000000][font=Tahoma, Helvetica, sans-serif][size=3][background=rgb(238, 238, 238)] I have succumbed and have an RX100 coming this week to be my B camera to my Sony Nex 5N![/background][/size][/font][/color][color=#000000][font=Tahoma, Helvetica, sans-serif][size=3][background=rgb(238, 238, 238)] I ideally want to shoot footage on the RX100 to look identical to that of the 5N so if I was to use both at a function I could easily mix in footage from both cameras to create a final piece.[/background][/size][/font][/color][color=#000000][font=Tahoma, Helvetica, sans-serif][size=3][background=rgb(238, 238, 238)] The constant question marks over shutter speeds at 50p on both cameras is also bothering me. I shot some footage at 50p 1/50 to see if the footage would be useable both in slow motion in a 25p timeline and also at normal speed in a 25p timeline. In both cases I was not too happy with the motion blur, It just does not look as good as shooting either natively at 25p at 1/50 or 50p 1/100 for slow mo in a 25p timeline.[/background][/size][/font][/color][color=#000000][font=Tahoma, Helvetica, sans-serif][size=3][background=rgb(238, 238, 238)] Based on the above I think you have to make a decision before you shoot any footage at 50p that is to be used in a 25p timeline. That decision is to whether your footage is going to be slowed down in post or not. Based on this answer you can then decide to shoot 50p at 1/100 for slow mo or 1/50 for nornal speed..although like I said I still think 1/50 shutter at 50p at normal speed in a 25p timeline still does not like as good as shooting natively at 25p on the camera (which you cannot obviously do on the RX100, but you can on the 5N)[/background][/size][/font][/color][color=#000000][font=Tahoma, Helvetica, sans-serif][size=3][background=rgb(238, 238, 238)] I will always be putting any footage I shoot in a 25p line so that is the only constant I am sticking with…its how I merge the footage from both cameras and get the best settings on both to deliver the best output….that is my main concern and caveat at this stage.[/background][/size][/font][/color][color=#000000][font=Tahoma, Helvetica, sans-serif][size=3][background=rgb(238, 238, 238)] With all this in mind I think I might choose to use my NEX 5N for 25p 1/50 footage and my RX100 for 50p 1/100 slow mo footage exclusively.[/background][/size][/font][/color][color=#000000][font=Tahoma, Helvetica, sans-serif][size=3][background=rgb(238, 238, 238)] If anyone can give any sage help and advice on this I would greatly appreciate it.[/background][/size][/font][/color]
