Hi,

which shutterspeed should I use for:

1) normal shoots / PAL / 25?

2) scene with fast movements / PAL 25p?

3) fight scene / PAL 50p?

Thank you!
 
The rule is usually to have your shutter speed set to twice your frame rate for the most realistic and smooth motion for video. For example if your shooting 25p on a normal shoot then your should set your shutter speed to 1/50, 30p=1/60. When shooting fast movement its usually alright to keep it the same but you can change it to something like 1/30 but I would recommend sticking with the rule most the time. If your shooting a fight scene at 50p then you could shoot at 1/100 and get smooth motion or if you want that gritty strobe effect than you could shoot around 1/125 or 1/250. Hope that helps!!!

No, actually the reason is so that you can emulate the traditional 180-degree shutter of film cameras. "Realistic" and "smooth" motion have nothing to do with it. Consider this: Video cameras, in NTSC land, have traditionally shot 60i, which is 60 motion samples per second, despite the nominal frame rate being about 30 fps. Yet the default shutter speed for (NTSC) video cameras is 1/60th second. 60i shot at 1/60th has been associated with the "live" or "local news" or "reality" look. So that directly refutes your claim.
 
But would you agree that motion does look smoother and more realistic as apposed to higher or lower shutter speeds. Intent or not that is the effect of using this rule! You could always ask my friend Philip Bloom if you still disagree.
 
But for example, I'm a skateboarder myself and I'd like to film some 30P skateboarding, and some 60P skateboarding to playback at half the speed for smooth slow footage. What should I set my shutter speed to for both situations? 180 degree shutter often isn't 'clear' enough.
 
Hi Guys,

I'm sure this thread is very important for beginners. Could somebody try to answer my questions?

UPDATE:

We have diferent opinions here. Thank you for the opinions, but we should come to a conclusion.

3) fight scene / PAL 50p? 1/100 for slow motion or in general for 50p

Thank you!

Only you should come to a conclusion. People can only give you ideas.

I think it’s very clear. 180 degree for 30p would be 1/60 and for 60p would be 1/120 (especially for smooth slow motion). Anything higher would give some sort of judder in the image (if that’s what you want). But this is where you would have to experiment to see what YOU like. The next guy would probably want a different setting and so on.
 
if you're outside(no lights,only natural) filming action sports at 60p(or 50p for you euro-types)and you want a CRISP look, bump up the shutter speed.EXPERIMENT. just be wary as, barry will tell you, of the flicker factor. pretty much any time else you want to stay with 60,120 (or 50,100-euro)respectivley to avoid any problems. And to keep Barry from yelling at you
 
I am getting a lot of problems with flicker when shooting in 25p in my EX1R. It looks awesome when in 50p but i don't want to shoot in 50p all the time.... It is just the progressive that is causing then flicker?
The shutter speed doesn't seem to noticeably improve this....


Thanks
 
I know this is not "proper" but to be honest, I love fast shutter speeds in video. Like, 1/320, or maybe even 1/500 or 1/1000.

i LOVE the look of this. very much.
 
It depends on the look you're going for, if you want frames to blend into the next and give a very smooth look then use a 180 degree shutter. If you want that staccato/strobey look (think Saving Private Ryan beach landing) go for a faster shutter. This article explains things a bit better:

Hi Guys,

nice links and opinions. Thank you.

On Saturday I will shot 3 girls on a white backgound. They will dance on the front. I'm not sure if I would keep the 180 rule. Maybe i will go higher. Maybe to 160 on 25fps

For the Story I will kepp the 180 degree rule.

What you think?
