Shutter speed for 720 / 60 p

I was watching the Philip Bloom tutorial and he mentioned that for 720 / 60 p, you should set the shutter speed to 120.

What if you plan to drop the 60p clip into a 24p or 30p timeline? If this is the case, should you still shoot at 120 shutter speed? Or should you drop down to the standard 60/50 shutter speed which you use for 30p and 24p?

Thanks
 
hello,

If you plan to render a slow motion clip from you 60P footage, AND you want a smooth looking motion then use at least 120 shutter speed. using something less such as 48 or 50 will introduce motion blurring to your moving subjects. Which is ok if this is the effect you want.
This wont matter if you just drop your 60p footage on a 24p timeline and use it as is. To get a slow motion you'll then have to corm your 60p clip to 24p.
 
I don't have an answer for your shutter speed question, but where is this Philip Bloom tutorial at? Thanks! :-)
 
at 60 fps the setting of shutter speed is boosted higher if the subject is moving and even up more if the back ground or camera is in motion. you can get away with a higher shutter works in slowmo 24 or 30 track with than you could get away with shooting 30p in a 30 track , i would pick the slowest shutter you can while getting the cleanest ( acceptable minimum motion blur). it seems like the more the shot gets slowed ,the higher you can get away with a high shutter. just like everything in the camera department , not one setting good for all shots , especially when available light is a factor.
 
you always want to shoot a divisible of the Frame Rate.. 24fps - 48 shutter speed (50 on the 7d which is the Closest) 60fps =120 shutter speed ( 7d 125 is the closest) and So on.
 
Good Note .. Try shooting at Lights with a High shuter speed and youm get Some Nasty Light Brownout, Know the Hrs Frequency of the Light source around you if shooting Action at night .. Just a nother Factor ... US is 60 Hertz so the Shutter has to be a divisible of that//

7d does not have 120- shutter speed..

Oh yeah, 125 thanks for that clarification, -been used to conventional videocam figures. Thats the concept. for smooth looking overcranked footage, ideal to do 60P at speeds of 125+.

In one instance I had a scene that required blurry slo motion, I used 48 shutter speed(videocam) in 60P and while it came out as predicted I wasnt fully satisfied with the motion. I think to do that requirement again I would approach it differently, like 60P at 125(or 120 videocam) and just apply motion blur in post, that way the amount of blur can be controlled.
