Carl - thanks for the info! An hour, huh? Good to know... Does jacking up the gain help in any way?

I don't think so.

HD100 Repeated Dead Bad Pix
 

Hey everyone - just finished up reading this thread...thought I'd share my experience on this issue. I have an HD100 (still under warranty) that I've had repeated, and uncommonly bright bad pixels develop with on a regular basis.

I fly a lot and so have been very careful to keep my eye on this issue and
at first I thought the highly touted pixel compensation menu was the solution. However, this has not been the case...

I have now had three subsequent shoots marred by significant dead pixel issues on this camera in fairly quick succession - one in Antarctica, one in Cambodia, and one in Oregon.

I should note that in each instance prior to pixel loss:

1. The pixel compensation program was run on the camera AFTER the camera was fully warmed up for over two hours.
2. The pixel compensation software was run AFTER each flight I made with the camera.
3. The problem has developed within 3-7 shooting days of the start of each shoot.

Of course, if I could I would simply shoot everything with a field monitor to be sure dead pixels aren't developing....but as we all know, this isn't always possible.

My thoughts are that a shooter shouldn't be expected to have to run pixel compensation software prior to, and during each shoot, never knowing exactly when - if at all - bad pixels have, or are developing. To me - regardless of what manufacturers may say to protect their product - this is a particular weakness in this particular camera. I've NEVER had this problem except with JVC cameras (and I have two at the moment - though at this point I may never buy another).

My current hope is that JVC has been able to address this weakness in subsequent models as it seems an inherent weakness in the HD100...at this point I'm just trying to figure out what to do with a new camera I can't trust.

Thanks you guys soooooo much!
 

I was freaking out about my lit pixel and BOOM that dang procedure fixed it! I owe you guys my career!

Thanks JVC.

(2) I don't think the pixel compensation program was ever designed to be run so regularly - you've probably filled up the memory. You are only EVER supposed to run the program when you discover a dead pixel (and originally they made you send it in to JVC to do it).

The problem you're relating (3) seems different to standard dead pixels - I'd be returning the camera for a replacement as soon as you can, or if that is not possible at least sending it in to JVC for evaluation. Hope all works out for you.

John - thanks for your thoughts on my posting...I agree with your perspective that I shouldn't have to run the pixel compensation program on a regular basis - and in fact, I only began doing so after consultation with JVC about my repeated, and regularly bad pixels that continued to rapidly develop after every flight. (And now, on nearly every shoot regardless of whether a flight is involved or not).

And yes, the camera is currently with JVC, again, for evaluation. I'll let you know what Doug Mullin's team at JVC says is the cause, and what, if any solution they suggest.

Bad Pixel Response by JVC
 

Hey John - just wanted to let you know that I heard back from the JVC techs today regarding the (latest) evaluation on my repeated bad pixels on my HD100:

The JC tech said the entire Optic Block needs to be replaced on the camera, which they are doing. I just hope I don't have the same problem in the remaining months on my warranty...

As posted in another thread, we had a dead pixel (or several) during an elaborate short film shoot in March. The camera was rental. I've heard of pixels popping in all HD cameras but mostly in JVC. We returned the camera. The rental firm in Geneva was not supportive, worse, they didn't check the camera before.

Skye - good news. I'm not seeing excessive reports of dead pixels (they are a fact of life on all CCD cameras), and your situation definitely sounded unusual. Fingers crossed this solves the problem for you.

Can pixel compen. be run "too often"?
 

I'm thinking we should run pixel comp. immediately before every shoot, just to make certain we are 'up to the second' ensuring that a new 'dead pixel' has not occurred. Is there any aspect of the pixel compensation processing that could negatively affect the performance of the camera if done too often? Or is this as benign as white-balancing, with no danger to the camera's performance no matter how often it is done?

I've just had my second dead pixel over the past couple of months...I guess that's not that frequent, but it's still a pain - just one dead pixel (white) is very easy to miss especially when filming in daylight. Noticed when filming a dark theatre the other night.

Yes, there is. If you do the sequence too many times, the memor fills up and will no longer allow you to perform the function.

Don't know why this is, but bottom line is - only do it when you have to.
