Thanks for this guide !!

Pls. try to use fresh raw2dng (compiled today) and tell me if you still have issues with pink highlights.

Where can i find the fresh raw2dng? also, is it mac compatible? I used RAWmagic so far since the normal Raw2DNG didn't spit out cinema DNG's which are needed for Resolve.

This is great. Cheers dude!!

Your shot looks epic too!

Thanks, you can find the whole test movie where i used this shot in over here on Vimeo:

Hey guys, just wanted to share some info i found out when using Davinci Resolve.
I had some problem with pink highlights, especially when i wanted to sharpen my video.
After some trial and error i found a way to decrease the pink highlight and gain better sharpness without boosting the pinkyness.

RAW file with color space set to BMD Film for maximum Dynamic Range


CC'ed shot with sharpening applied


CC'ed shot with sharpening and pink removal


Basically what i did was to add a layer mixer node as very last step as you can see here:

The layer mixer node composite needs to be set to add in order to work for this removal.
Now the two nodes it created before the final layer mixer node are the ones where going to work in.
Set the top node to 0% saturation and pull down the Y gain on the bottom node like this:


Now what we did was separate the Chrominance from the luminance, this means that the top node contains the information of exposure and the bottom node contains the information about the color.
If we add a simple sharpening to the top node it only sharpens the black and white channels and doesn't touch the color noise meaning a cleaner/sharper image than you would have with normal sharpening.

Now we added some sharpening to the top node so we need to do the opposite thing to the bottom node.
So go ahead and open the sharpen/blur tab for the bottom node.

Make sure that you turn off the gang button (it's the tiny shackles on the top left in the picture above), this gives you access to adjust the levels individually.
Now these are the settings that worked for me in this picture, just try it on your picture because the settings could of course be a bit different.
If you pull up (meaning less color) the red channel radius you will see that the pink highlight is disappearing together with the red color noise if you shot at higher ISO's.
Now you can use the other 2 channels too to remove some more unwanted color noise, and this trick only removes the color from that color noise meaning more detail with noise reduction turned on instead of blurring the whole picture as the normal noise reduction does.

And there you have it, less noise, no pink highlights and a sharper picture WITHOUT losing detail!
Now i wouldn't say that this is the best or only way, it's just the only way i found out to do this.
Hopefully it could help some of you guys :)

P.s. sorry for my bad English, it's not my native language

Looks awesome. Great work. What were your export settings for YouTube?

H.264 .MOV file
Limit data rate to: 50.000 kbps (which is ridiculously high, i know but just wanted to see if i could upload it with fine details like the added grain, but it's not that visible too bad :( )
Maximum render quality and stuff like that

Ok, thanks, I'll try that. How many minutes can I record in FullHD raw with a 64GB card?

Until your card is full, so approximately around the 12 minutes to 15 minutes.

Nice shots! what lens did you use?

Thanks, i used three lenses in total but mostly the Samyang 24mm T1.5 lens, it has amazing color and contrast and holds up well on T1.5 (f 1.4)
THe other two where the 24-105mm f4L IS from Canon and a Sigma 8-16mm f4.5 / 5.6 but that's an APS-C lens so i could only use it on 16mm to get full coverage for the Sensor.

Will get back soon to the prison with a slider and a new lens, the Samyang 14mm T3.1, Yay!

I shot it all on 1920 width and about 817 height (2.35 aspect ratio), Full HD is not stable with the 128gb card, max is about 2:1 ratio.
I'd suggest looking for the 64gb 1000x card, it is faster according to most people and Komputerbay.

Went on a few photo shoots and decided to shoot a bit of video too.
Still learning Davinci Resolve, tried to create a 80's washed out look, no full colors and no complete black to white spectrum.
All files where converted to Cinema DNG and had to find out how to lose the pink highlight, after a few tries i found a way to filter out the chrominance and luminance separate so i could get rid of the pinkyness without too much loss of detail and color.


Most of the footage was shot on 1920 width (2.35) except the footage of the abandoned castle, it was shot on 1600 pixels width because i only got the Komputerbay 128gb 1000x for one week now, that shoot was 2 weeks ago.

Btw, Komputerbay themselve don't suggest using the 128gb 1000x cards for the ML hack, they suggest using the 64 or 32gb ones because of higher speeds.
Just some advice i got from them through mail

Lovely numbers, now if only our cards would reach up to those speeds then it would be a lot easier to copy files :p

If i'm not mistaken, USB 3.0 builds the dataflow up to the maximum speed while Thunderbolt is always at maximum data speed.
At least that's what they told me at the apple shop
