bad pixels at high ISO

here's a clip from a shoot last week end. i've had the k-5 for about a month, and i'm having pixel issues out of the box.


i magnified the pixels to be more clear. in this shot, i locked the ISO for the interior of the garage. at the beginning of the clip it's to dark, and you can see the bad pixels. when i go to the exterior (which wasn't planned) i tapped the unlock button to adjust and you can see when the bad pixels go good...or see the light so to speak.

any idea on how to fix it?

Have you tried using pixel-mapping in-camera? That should (at least in theory) fix the problem.

this is what pentax says, and makes sense. when constantly shooting, the sensor gets hot.

"Defective pixels can be corrected in the K-5 if you run the Pixel Mapping function in the camera's Set-Up menu. Pixel mapping is described in your camera manual on page 311. In some cases, such as during movie recording, when the sensor heats up, pixels may become temporarily "hot" and then return to normal when the sensor cools down."
