F55: Rolling/Global shutter Alexa, Red, F55

It's just that if you have shot with a CCD camera there's nothing unique with regards to rolling shutter with a CMOS global shutter sensor. They behave the same in this respect.

There are other advantages but this test was on rolling shutter and I look upon it as just that. Enough said.

WTF. Not even a test. An exercise in self indulgence.

How is this not a test? It's a test with a predictable outcome, but it's still a test. Sheesh.

I pan to follow motion all the time and have never lost a shot to rolling shutter, but I don't make many bicycle against fence movies. I'm not trying to diss the technology. I think it's great there are cameras we can use when very specific types of shots require them.

Yes, you pan to follow the action, but what do you do with all the static objects in the background? "Excuse me Mr Oak Tree, could you lean slightly to the left to compensate for my rolling shutter?"

It may be obvious to you but it's a very handy, short clip to show producers/directors or any other crew member who may not understand the implications of a rolling vs global shutter.

Imagine a Producer asking "Why do you want to shoot the red carpet scene on the F55, I'd rather we stuck with an Alexa/Epic?"
 
I don't pan like a teenage girl on Redbull, so the oak tree in the background stays nice and straight. Clearly we have different shooting styles. Like I said, it's a nice feature to have for the cases where you need to shoot something that might skew. I'm not dissing it-- I'm saying it's not something I've EVER lost a shot to, that's all.
 
no one needs to pan like a teenage girl on redbull, but what if your background is moving? for example car rig, steadicam, crane, etc.. etc.. Many think global shutter will just look "better".
 
(diggin up an old thread)

I'm surprised that the Red and the Arri would use rolling shutter. While most of use would not pan a bike along a fence, a lot of us might want to use strobe lights as an effect, in say, a music video, like I did a few days ago, with my FS700 and its wonderful rolling shutter.

The video turns out ok, but the rolling shutter effect is apparent to my eyes (though not the client's) so I'm not 100% happy with it.

Now I don't think at this stage of my career I want to throw $30K away for a F55, as wonderful as the camera I'm sure it is. I wonder if there are less expensive alternatives among the cinema-camera class of cameras out there? The F5 doesn't do it, for instance.

For heaven's sake - my HPX170 has global shutter... shoulda filmed the strobes with THAT instead.

Thanks.

Ever done handheld? Looks like shite with rolling shutter cameras (though the Alexa and Epic are almost fast enough to get by)
 
I am a little confused though- doesn't RED offer a "motion" mount that changes their Rolling shutter into a global shutter?
 
Rolling shutter affects every bit of the image with ever bit of movement. You don't have to pan your camera or shoot spinning propellers to be affected by it.
 
3900 dollars for a global shutter is definitely worth it - I mean, just look at the price of an alexa, F55, Epic - I am sure that if alexa had an add on price of 10,000 people would buy it, and in a hurry no less.

1.5 stop of light isn't the end of the world really either - the dragon sensor has what, 16 stops of light- if you give up 1.5 stops - it's not like the camera will be unusable by any means.

I stop of light from F2.8 to F4 is not a horrible takeoff for a global shutter either. I mean, if you had a global shutter button on a Canon 5D Mark III that bumped you up from a F2.8 to F4 for an instant global shutter, I am willing to bet that people WOULD press it. And since it's a lens mount, you can remove it and install a regular lens mount when needed. So when you do have a scene with a helicopters main rotor spinning you could slap it on and use it. Surely we all have lenses that we slap on that cost many many times the cost of this option that we use when the need arises. And you know - sure it takes more time than a lens change, but does it? If you have to adjust the follow focus, or the mattebox..... etc.

I have NEVER used the FCPx rolling shutter function - does it work really well? I see rolling shutter artifacts everywhere I look- on tv, vimeo, youtube even cable and netflix footage. If there is a rolling shutter fix in NLE's is it just not used that often or isa it not that effective?
