In the cinematic or filmmaking cinema sensor space, many cameras (especially the Alexas), seem to be more than good enough. Are there global sensor cameras that apparently have a more cinematic motion cadence and less noticeable rolling shutter? Also having an extremely fast readout speed, I suspect, may not let the image have the necessary softness required for a cinematic image. I am suddenly wondering whether film stock had issues with rolling shutter. Not to mentions the 2-3 stops of light loss and lower dynamic range of global CCD sensors. Also many CMOS sensors have global shutter circuitry, so things are not exactly black and white. 2 Digital Bolex claimed their GS CCD sensor helped give better motion and hence was more filmic and I'm inclined to agree with them given the tasty footage it exhibits. ARRI Alexa/Amiga have the lowest RS (2-6ms) out of any non Global Shutter cine cam, so you can't really lump them in the (average) CMOS GS camera category. 9 hours ago, newfoundmass said: Rolling shutter went from being one of my biggest concerns to something I don't even think about these days. The only cameras I notice having bad rolling shutter these days are the Sony a6xxx cameras. Every other camera has made huge leaps, to the point that global shutter doesn't interest me at all. 1 EOS R & Z7 have severe RS in 4K. Fuji XT2/XH1 are also pretty poor.. that said, it didn't prevent me from buying both XT2 & EOS R which i both consider "filmic" in the right hands There are ways to avoid RS.. except if you're filming from trains etc.. hansel 1 Quote Link to comment Share on other sites More sharing options...

But so what? Almost nobody in the viewing audience but myself and a few other geeks will ever notice it. If the story is worth a crap you will not notice Anything camera wise unless it is so dark you can't see the story. 99% of the people in the world don't even know what RS is.

Imho people notice geometry changing in those situations they get distracted, maybe film industry should make a survey about that Imho when there is a clean panning (no vertical jumps) it's a mistake of the DOP if we see rolling shutter artifacts even with those cameras: they could put the camera in vertical, and shoot that scene in vertical to avoid rolling shutter, than crop and reframe the scene in post production loosing resolution, but less artifacts. with a ultra HD 3840×2160 pixel camera we would have width: 2160px height: 1215px image in any case it's far better than full hd and may be right for one scene. now you remember AAA movies with rolling shutter, and those movies are probably shot with camera with higer resolution, they could trade pixels for "fake global shutter".

androidlad Posted December 4, 2018 Share Posted December 4, 2018 Just a reminder that film cameras/digital cameras with mechanical shutter aren't global shutter, that half moon shutter doesn't expose one complete frame at the same time.

Film cameras can exhibit very mild rolling shutter effect, as the rotary shutter mechanism sweeps vertically across the film plane. Quote Link to comment Share on other sites More sharing options...

A movie I can watch a particular scene? thx! Quote Link to comment Share on other sites More sharing options...
