Here is a video I did with one of the 6 K-5 I had to get back...
But I've found workaround to the Video HotPixels issue ... so here I give you the trick, translated by google from Spanish.
This is the post where I was discussing the problem with other users, I hope it could help !

----------------------
Well, I wanted to share this "discovery" with those who suffer this problem and hope to relieve headaches (mine sure) ...
I don't know if this method was described somewhere, but after searching everywhere I have not seen anything like explaining and solving this problem. but I'm really excited about this method and hope that it'll be fixed with a Pentax firmware.
After many tests, I found a / (the ?) solution, I smiled back and finally this allowed me to stay with my K-5 (which has not just one, but several hot pixels).
THE TRICK (not sloppy or messy):
1 • ... is, to NOT DIRECTLY BOOT with VIDEO MODE and shoot VIDEO!
2 • I mean, if you start up in VIDEO MODE choose a PHOTO MODE nearby on the dial, USER or Automatic (just for ease)
and ... VERY IMPORTANT! PRESS [LV] - Live View, to turn the LCD on. (No need to take pictures or anything else ..)
3 • Finally, with the dial, set up back to VIDEO MODE ... that's it !!! ... and record as long as you want, freely .. even in very low light ... the result is PERFECT! (In my case it is)
I think this activate the internal map of dead pixels (or hotpixels) as PHOTO, but in VIDEO MODE, really what the K-5 is supposed to do automatically in VIDEO. I guess Pentax will solve it by a firmware as it will be done soon by Nikon.
Why are there spots in the video I shoot with the D7000?
I hope this method can be useful to others and enables them to record videos with the K-5 without hot pixels.
I'm interested to know about your tests.
