Sony XDCAM EX

I have no idea how he ended up with that conclusion!
pre-production, I don't know....
I've been around the HVX200 (tested) and JVC HD100 (owned). They're no where close.
 
Gerry,
I will post when I gather some data.
Remember, I'm not the only not having an issue.
BTW, I'm not 100% since I'm viewing with a monitor that is a tad underscanned, but even starring REAL close to the LCD, I see nothing.
I'm going to capture soon.

Also, Paul surely did not mention anything with focus.
Eric from dvinfo noticed it was tad more at further focus distances, but it showed either way. His is not as bad as Pauls.

Hey Steve,

Sounds encouraging about the light sensitivity & I look forward to the clips. Adam Wilt mentioned the vignetting caused by the auto focus (in the pre-pro model), & I happened to notice the weirdness in the macbeth chart when the camera was trying to focus on the rapid movement of the chart flipping- coincidentally (or not) in the same area of the image, the upper left corner. I'm not enough of a techie to know what the correlation is and how autofocus might cause vignetting.

Thanks!

Gerry
 
OK...
Here's the deal.
I've got it...
Now I'm wondering if they all have it and some are not looking hard enough for it.
Hmm...
Is it bad enough to return, will it effect normal shots, it's hard to say.
I know one thing, Sony is going to have their "ear full" on this one.
This should of NEVER left QC!
 
Steve... would you mind elaborating on the situations that have caused this for you, please..... I've not been following this much, so I haven't seen the talk on the other forums.

Thanks,
Jason
 
Bad enough - a screen capture coming. I just let the salesman know about it.
He has heard nothing about it.
At first I though I could live with it. I then walked around run-and-gun. Sure enough I could see it on the wall on a couple shots.
Don't trust your monitor. Capture it.
 
Is this widespread? Probably not enough owners to tell yet, but I wonder if this is an alignment issue that can be corrected or something in the overall design. I find it hard to believe Sony would consider this acceptable on a $7K camera, so hopefully it's just an early manufacturing hiccup.
 
Manual Focus
Happens between 10-25mm.
Focused far, please excuse white balance.
Dropped brightness a tad to better show problem.
It has the blue tint that others are seeing.
Not sure what to do. I let the salesman know.
I'm going to try to get hold of a Sony tech.

Sorry to hear you are having trouble Stevet. My anxiety level has now been raised, but I guess we can only hope for the best and plan for the worst. I think I am going to contact my dealer and make sure that if this problem is happening with my camera that I can return it with no questions asked.

Stevet, sorry to bother you with the following request and questions. Can you find a way to host a small clip ( 10 seconds, 15 seconds),with the issue? In still shot this s very noticeable, specially on the top right corner, but how does this look in movement?

Also, is this vignetting happening in the overscan area? I mean, Is this going to appear on HDTV, or is it inside the safe area?

Do you find this unusable or unacceptable for production?

Cheers,

Sérgio

It happens in the overscan area. At least on my 24" DELL using the component inputs. This still bothers me. The overscan area varies on different monitors.

Also, the vignette moves a bit when the OIS system is working.

The region it happens is between 10-25mm focal length. Oddly, It does not show at full wide (5.8mm)

This PC mov file is not from my camera, but from Paul Joy's EX1.
He has returned his camera and is waiting for another:

Mine does the same thing, it just shows up more to the right. Pauls is more on the left side.
 
I am now sure Sony know about this problem and I think I am doing the right thing by hanging fire on buying one until the new year.

Wouldn't be suprised to see a recall, and also that we won't see many in the next few weeks while they fix this error. Regardless of whether it's in the overscan area or not, I would not accept it and the camera would be sent back immediately. You don't get this problem on cheap consumer cams, so you shouldn't except it on a camer as expensive as this.
 
Agreed.
I spoke to a Sony tech today as they were setting up the in house EX1 to test for the vignette issue. It's possible their camera does not have it, but the percentage so far is for sure greater than 50%.
 
MOVING picture

MOVING picture

The most important thing for me is the MOVING picture. (200$ photo-cameras have much better resolutions)

The stills resolution is clearly better compared to the HVX.
BUT, and this is the most important point: What about fast moving objects?

Will objects moving faster than 1/15 through the picture be ignored, if they don´t accidently hit an I-frame?
(Does 35Mbit/s have a smaller gop?)


Please, someone post some successive frames of a fast moving object.
After they have been actually recorded with MPEG codec.

This is the crucial reason to prefer the HVX over EX or vice versa.

How much filmlike does the Ex´ 1080p25/24 look?

This is what you notice on the screen and what makes the difference in my opinion.



Anyway, the Ex has a lot of advantages, please post some pictures of Moving objects or quicktime samples to convince the sceptical.

Much appreciated, Stevet. Puzzling indeed.

MPEG doesn't work that way. It doesn't have to appear on an I-frame in order to be included in the GOP. The GOP encodes the changes between frames over the course of a full 15-frame GOP. I mean, think about it -- if something needed to be registered on an I-frame in order to be included, you could never record a camera flash or something like that (not that HDV does all that well with camera flashes, of course, but you do at least know that one occurred!)

Every frame gets imaged as-is. When they get recorded, only the changes between frames are encoded. A fast-moving object that only shows up on one frame out of an entire GOP will still show up, because the frame that it appears on will represent a significant change from the frame before, and that change will be encoded.
