I was export test for a client who works on AE CS3. I have exported 8bit TIFF, 16bit TIFF, ProRes, 10bit Uncompressed and 8 bit TGA and all clip seem the have the same artifacts. I get blue, red and aqua dots in the dark areas of the shots. They are not on the original clips.

REDCINE 3.1.8
Mac OS 10.5.6
MacPro 8x3GHz

Any idea on how to get rid of those? And how it could happen?

Thanks a lot
 
That is weird. I don't know much about Red bugs, but I didn't know you could get this sort of thing. I though this sort of problem was limited to clipping out on the opposite end... never heard of "cold pixels" ??

I would like to hear an explanation or get a link to a thread on the subject.

The good thing is that their color is just like blue screen, and not something you'd come across in your shots. Also they would all be the same exact value... Also, it seems they are all supposed to be black pixels. Fixing it should be simple. Something like a color replacement or chroma keying would be easy and straight forward.

Well, actually, there is one pixel on the person's hair that isn't the same value of blue... but it should still work well.
 
And a little bit of purple... weird. What build are you using on the camera? I think there was a thread about something like this way back.

I am not going to be able to help, just to clarify. But I think I am quite sure that if you searched for a while you'd find that thread... and you can always call the Red Support team. They would love to help you I am sure.

I don't know the direct number, but I bet you'll be directed to the right department if you call their main line. Phone: +1-949-206-7900
 
Check your OLPF sharpening settings. Set to zero first and see if they disappear (which they should). Then adjust until image is sharp but not so sharp that you get the edging artifacts.

Are you processing at full or standard in RED cine? What color temperature?
We saw pronounced blue dots it Tungsten-balanced footage using standard processing. Flip it into Full and they went away. Just took a bit longer to render.
 
A 'bit' longer is quite an understatement, but, yes, I've had the same experience.
