Baldand, as requested I PMed you links to some sample RAW footage with pink dots from my 650D. Please let me know once you've dl/ed them so I can clear up some space on my Dropbox acct.
Thanks,
Dave

Yes, it supports .RAW files also. They would also be useful for me.

A small request to people using camera with Pink Dots...
MlRawViewer 1.1.6 introduced a new GPU-based bayer pre-processing option that tries to identify any "bad pixels". This is mainly for dead or hot pixels, but I have also been testing with a little material I have from PinkDot cameras, and I believe it can also detect and suppress many of those with a minimum of impact to the rest of the scene.
The feature is still in development, and would need some more tuning to be totally effective in the pink dot case. In particular I probably need to change the work flow so you can "train it" on a certain resolution, and then re-use that training data in other shots.
If anyone is working with raw on those cameras, and would be interested to help me develop this further, please try out the current code and let me know how it goes. I would also appreciate being sent more such MLVs to test it against.
Thanks!

Pink dots in RAW is a well known bug, you can fix that by using PinkDotRemover. You're welcome.

Please, can you upload somewhere a very short RAW or MLV file with your problem?
The cold pixel fix fixes only true cold pixels (sensor defects). It make no differece, whether the cold pixels are located in dark or bright areas, they are fixed with the median of their neighbours

Glad I could help! If you have a mac nearby, the best tool i've found so far is PDR interp by rewind. It's written in java so i'd assume it would run on a PC as well? It's very robust and produces superior results (imo). It certianly can be difficult to find though, as its buried in a PDR topic somewhere on the forum. I can re-up it if its beneficial, or someone can reply to this with a forum link if they find it.
Sidenote, if you're affiliated (even remotely) with an educational institution, you can get Adobe CC for $19/mo if cost is an issue with adobe's suite of stuff. I'm not particularly a fan of leasing software... but its an option.

Dave, I was able to replicate the issue after poking through frame by frame. After some testing and mucking around, i'm leaning toward a cs2x2 issue. AE doesn't show the dots because whenever you're working with DNGs it will automaticially run dot remover behind the scenes, thus a clean image. Actually, all adobe tools do this when working with raw/dng. I baked in the black dots using Davinci to export into a prores sequence and took that into AE and that made them visable.
My best suggestion would be to take the source footage and without using cs2x2, or any PDR for that matter, check the frames. Sure it'll have pink dots but it will identify the issue: either Davinci's raw engine is wonky (not that likely) or its cs2x2 (more likely).

Hey Dave,
I tried it on my mac using davinci 10.1, didnt' see any noticable difference between DR and AE or even lightroom (for raw/dng viewing). Can you post a screenshot?

Can you update PinkDotRemover to remove dots from (2.20:1) 1344x610 .RAW file (recorded with mlv_rec)?
Or is there more programs made for remove pink dots?

Why would you use such an outdated version? There's no reason not to update

Hi Alex,
I'm was having an issue with green dots in overexposed areas from my 650d... i used your raw2dng whitefix version and it got rid of the green dots except left some black/grey dots in the overexposed regions during playback in Resolve 10 lite. I went to inspect the dngs with windows picture viewer and these dots couldn't be found! What could your program be doing to cause Resolve to interpret these pixels as dark grey?
Thanks!

Hi Dave, I asked the same question a while back and received no real solid answer. So I went ahead and downloaded the latest build and 1280x720 is 99% red dot free with PDR tool 7 or 8. 1472x626 however is loaded with dots. There is a cool tool a1ex made called " raw2dng-cs2x2...hdlike_noise.exe" which cleans up the 1472x626 pretty much. Just Google that tool name and you should find the threads with download links. Also, I have found that adobe camera raw (ACR) used with most adobe software like After Effects helps with properly displaying the tool converted DNG files. I'm not sure why but that's what I'm having to use after PDR is applied. Yes...it is a mind bender and a bummer at times but just imagine what the devs go through...upmost respect for those guys!
