Shooting in a faster shutter has advantages for me and still allows a moderate amount of motion blur and sharp images. Much of my footage would contain too much motion blur if i shot at 1/60. For example, this video below I shot last weekend from the back of a jetski on GH1, 14-140kit, 720p 60fps at 1/125 shutter, video was edited and exported for vimeo at 30p. As you can see, still has a pleasing amount of motion blur. ( I did miss pressing that damn tiny lock exposure/focus button a few times....big fingers..small button) :-)

Actually for 60p a shutter of 1/60 is still recommended for natural motion blur, normally you would use 1/120 if intending to slowmo in post. I do sometimes shoot in variable shutter mode as it allows faster stepless exposure compared to aperture changes on the fly. In my game it's not so important to stick to guidelines..... as it's live action, one take, getting the content is a priority. Major broadcast accept it, I just had a 30 min show featured on NBC Universal Sports Network that consisted entirely of PAL, NTSc footage shot on GH1/2 at shutters between 1/50-1/500, but I appreciate most people on PV are from film backgrounds and follow the industry guidelines .... outside of that, plenty of news, sports and docs get shot on auto mode. Thanks for the kudos.

I used to follow that "stick to a shutter of 1/50 rule" I personally disagree with that, film however you want. Whatever looks great to you. I haven't shot with a shutter speed of 1/50 in two years I always keep my shutter speed at like 1/100 or higher. I have never used a ND filter in my life and really think about the GH2 isn't going to produce the same motion blur you see in cinema cameras regardless if you stick to the 180 degree rule or not

@Rambo Ah, I guess I've never used 60p for anything other than slow mo. Guess that explains it. We work in different worlds my friend :) And yep, for the type of work you do it's all about getting the shot no matter what!

Questioning one's assumptions is a good way of creating new experiences, but also it brings about the unfamiliar, which we know from the past, offends the eye of the traditionalists. We rarely learn from the past ;)

Btw @Rambo really nice work! :)

shooting in 25p and without a set up of lights

I use 1/25 most of the time in lowlight, for not increasing the iso tooo much (as it decreases de dynamic range and increases the noise, i never go upt of iso 1000), but with 1/25 there is a decrease in resolution (at least to my eye), so 1/50 whenever i can

in daylight i try to use 1/50, but also 1/100 if there is no movements on the shot (i try to avoid the use of the nd filter that i have), because if there is no big movements, there is no need of motion blur

@DeShonDixon Well, there you have it :) Even though that defies the laws of film and all known standards, it looks the opposite to you and I guess that's all that matters.

@Jumo, Either way, I just got schooled by a video beach bum! =)

Haha....that makes Barry Green a "beach bum" too, not sure he would be happy with that. :-) but he would get this question re 60p 1/60 at least one a week.

You know, its funny how things work, in the GoPro World we actually ADD ND filters to lower the shutter speed so that it eliminates most of the jello wobbles caused by the fast shutter and hi Freq vibes, also to blur out propeller blades in the frame.

Time to head back to the beach.:-)

120 shutter for 60fps has always been mechanically locked-in for movie cameras (those which have a 60fps or variable setting). the Bolex reflexes had a variable shutter which was seldom used although the manual suggested, "In dazzling light, such as snow and water.."

We used that variable shutter lever to do in-camera tricks like fades and double-exposures. Nobody I know used it to reduce exposure time - the tiny ND filters between the lens and the film gate did the trick.

If there has been a big breakthrough with motion blur, IQ, and other things using a higher shutter speed, we'd know about that. 180 degree is normal motion blur, I'm sure there have been a lot of tests to settle on that.

That would make 60fps with a 120(or 125) degree shutter. Working in and with news, that was the norm. 2 and a Half Men uses 3 35mm Panavisions all at 60fps and 180 degree shutter, 1/120.

I guess shutter speed is a choice for a certain look. So do what you please.

Why should you use ND instead of shutter? hm... No absolute (and there will never be) but a bit of a clue:

1) Realistic Motion blur in post looks unrealistic if it has to be on an entire image. (In 3D we generate a Velocity pass which calculate the movement of every pixel making it more flexible and accurate to produce a realistic motion blur but from a plate it is very hard and the few softwares that does it are kinda... wip at the moment). 2) It takes a lot of time to the R&D to nail the thing and even when they get it, the result is far from a real motion blur. 3) Rendering can become easily inaccessible for the latest i7 and could require more than 32go ram.

The motion blur added in post that I'm aware in the VFX industries are mostly for green screen since you do not want motion blur and a few other cases that would require rotoscopy by breaking the image and re-making the motion blur (and it's a pain in the ass to do this) but otherwise you tries to do everything on set.

If you lack the money (no money for an ND filter but money for an i7 is kind of ironical) for a ND filter and are willing to extend your time in post then I see no reason that should stop you. But motion blur in post can quickly be categorized as Advanced compositing and unless you've studied the thing very carefully you'll have very hard time.

A faster shutter speed will not reduce rolling shutter, as the rolling shutter always reads the sensor out at the same speed regardless of shutter speed. They are entirely separate processes. In fact, a slower shutter speed can often improve the look of rolling shutter effects by hiding them with motion blur.

@Noelpuppet - try the Genustech Eclipse vari ND. Yet to have a color cast problem.
