OIS - problem / solution

We shot some vehicle to vehicle scenes (tracking car to motorbikes) using DVX with Cavision wide angle adaptor. Camera was remoted out on a jib arm and monitoring was limited in the circumstances.

Viewed rushes later : On occassion the lens shade came into frame. It came in to varying extents and always at varying angles. Hard to know what caused it to come and go (even in the same sequence)

We are trying to determne whether we had the OIS on or off at the time. Best guess it was On and not handling the motion. This caused it locked it self in a wierd off position.

It is not easy to test because we are not sure when it will occur and we do not want to waste limited and tricky shooting time on the road doing tests

Anyone know what the "floating" element does when OIS is OFF ?
ie.Is it fixed rigid in the unit ?

Any thoughts and experiences.
 
I am having serious issues with my DVX and what I think is the OIS/Gyro. The strangest part is I get no warning what so ever. When the camera is off it "floats" or clicks properly. When I turn it on it might be black? it might flicker numerous times on and off rendering the screen black. It's not setting right. I have tried to reset the camera, but it when I do that I figured that it would reset to factory settings? should it? I am more than slightly frustrated with this. Anyone with any ideas?
 
Hey,
The camera has reached the point to where it's states STD 17% and is black nothing just black. I have no warning displays on the LCD. I really enjoyed the footage I had gotten off this camera until this point. I can set the camera on the table and it would flicker on and off. I am going to post some video from about 4 days ago while it had some picture. I post with video and maybe this will help with suggestions.
Thanks
 
idvfilms, get your camera into the hands of a panasonic repair technician. I had issues with the audio on channel 1 being complete garble, regarless of what setting it was set to or what was used as input (wireless lav, wired shotgun, internal mic) and sent it to panasonic's repair depot 3 times. Because it was an intermitten problem, it wasn't acting up for Panasonic. The third time I sent it back, I was insistent with the dealer about the issue, was able to show the dealer the problem, and had a tape for the dealer to send to panasonic showing them the issue for themselves. In the end, panasonic apparently replaced the guts of the camera, admitting no fault, because they couldn't find one.

I've babbled here, but the moral of the story is get it into Panasonic's hands for repair. If it's under waranty, you won't pay. Regardless, it's an internal problem, one that likely exceeds the expertise of anyone on this forum.

Just my two-cents worth..

Optical Image Stabilization typically works by shifting the portion of the sensor used to create the image as part of its program. It comes closer to the edge of the chip and is off-center at times. If the shade or accessory vignetts or almost vignetts in underscan this shifting about will cause the vignetting to appear in one or more corners in what may seem like a random way.

The solution is to turn off the stabilization or find a shade/accessory that does not vignette during camera movement with the OIS activated.
