Alexa Shutter Question
Posted 15 March 2011 - 06:54 PM
This seemed kind of strange to me; motion blur makes sense if the rectangle is moving fast enough and the shutter is 1/48, but why does it appear pulsed? As if it's recording two frames and mixing them together? Shouldn't it be a continuous blur? It also seems like one of the two images (or pulses, or bursts, whatever you want to call it) is more exposed than the other. Is the alexa taking two images at different exposures and mixing them together for latitude, like a scanner? Or is there a much simpler explanation I'm missing.
Anybody have any thoughts?

If someone with some more technical knowledge about this could explain further I'd be very interested!

What's the rest of the chain that produced that picture? It looks more like an error in some post equipment or software than a camera thing.

Looks a lot like a frame merge similar to a 2:3 pulldown cadence. Just not possible coming out of the progressive-only camera.

I feel that picture is giving that kind of blur. Because of "CMOS CENSOR" which records image similar to interlys scanning technology. i feel this problem wouldn have come with a camera with "C.C.D CENSOR".Because, i remember i saw a comparison footage of same image shot using cmos & ccd. In which cmos has this kind of image due to its image recording method.
Its just a guess am sorry if am wrong
