Would it be at all possible to have a script like BATCHelor (http://www.magiclantern.fm/forum/index.php?topic=5645.0) create its cineform proxies using this preset? This way we'd be able to jump the timeconsuming AE render, there might be stuff you'd still tweak by using the DNGs but otherwise you could render usable cineform right out of the .RAW files saving tons of time and space...

I'm not sure if it would be possible. Ill definitely look into it and see what I can uncover because, yes, I agree - if one could skip the AE render, - things would be much smoother and easier.

Ill look into it.

When using the preset, is it made for using a correct exposure or with a ETTR-exposure?

It was built with exposing to the right. It has not be tested with Duel ISO video however. Just FYI.

I really like the dynamic range and image quality of Duel ISO. Man, I really wish this was possible for video on the 50D.



Not the prettiest of photos, but it really shows off the nice range between highlights and shadows.

Flatz Updated to v2.3. Flicker issue solved!

http://www.dlwatson.net/flatz-preset.html

Different cameras have different isos... 128K I don't think anything has native, maybe 5d3 or 1dc/x.

That makes sense. Thanks for the clarification.

Dual iso works with "analog" ISO only. 12800 is definitely digital

Then why is it even an option in the Duel ISO settings?

Hi. What ISOs and converters did you use for this shot? I've just checked with latest tragic lanter build and latest cr2hdr (for windows) from first post here and still get greenish shadows.

I used ISO 100 and 1600 with the latest cr2hdr for Windows. They converted beautifully for me.

Attended a wedding and tested the duel iso for my 50D. Some beautiful dynamic range.



When nighttime hit, I tried to see if I could do something like 800/12800 but even though it was selected, it still defaulted back to 800/1600. Maybe a bug? (I know it would be incredi-noise, but I just wanted to see how bad it would be).

Thanks. Ill take a look and see what I can do.

Could someone supply me with a set of DNGs that experience the flickering for troubleshooting purposes?

My dropbox folder to add https://www.dropbox.com/sh/os0i5blap1vnqpl/1uSFKQPj9M

Thanks

also i dont ask shit people for their step by step color grading
i ask from the master of art like D.I.Watson

I'm no master at anything.

In regards to your mannerism, there is no reason why anyone should say something is stupid. You might think it's stupid, but have the common courtesy and respect for your fellow filmmakers and give constructive & encouraging feedback. Or don't leave feedback at all.

The Flatz Preset is built using the Parametric and Point curves. The only slider which is used is contrast. I have yet to experience any flicker issues using the preset even just now in a basic test.

Another way to apply the Flatz Preset is to open your DNG's in Bridge as a sequence, apply the preset to a frame and synchronize to the other DNG's.

Yea! Get well DL.

Derrick

DLW, get well soon! All MLers pray for your speedy recovery.

Thanks guys! I appreciate the kind wishes. I'm much better now.

Darn, it looks like a great profile, but I get flicker with this profile. 

I haven't experienced flicker yet - I will look into how to troubleshoot and solve this issue.

Anyone to confirm what goldenchild9to5 has tested?

Here, I did a 50D ISO test. Click on the image to see in full-res.


ISO test with RAW set to normal exposure.


ISO test with RAW Exposure set to 5+

Looks like ISO 100 and 200 are very close. Hope this helps!

D.L. Watson I want to say thank you for making this workflow. It does save a lot of space. I have a question though. Could you do a comparison between using the Flatz ACR preset with post sharpneing and contrast on versus Tenchnicolor picture style with post sharpening and contrast on regular H.264 footage?

Sure. I can do that. Right now I'm pretty sick but Ill try and do that in the next couple days.

@DL Watson    Apology for missing it somewhere, but which 50mm lens are you using?  I have the 50mm EF 1.8 and 50mm fd 1.4

The cheap $125 EF 50mm f/1.8 II.

Playing around with RAW again. This time using the insanely sharp and quite affordable nifty fifty lens.

Workflow:

RAW > ACR > Apply Flatz Preset > Render to DNxHD > Edit & Color Correct/Grade in Premiere

so exposing to the right, is exposing for the highlights to be correctly exposed?
I always thought that exposing to the right, meant for everything on the histogram to be further right which would in turn make the shadows brighter, as opposed to the highlight darker. Someone correct me if I'm wrong.

Exposing to the right is to push the highlights to as far as they can be recovered, thereby introducing more shadow detail without introducing more noise by bumping up ISO. Which because the background is at a higher exposure then the foreground, the histogram is exposed at -1.7 (at ISO 200) - the most I could expose to without clipping highlights on the car and in the far building.

If you clip your highlights, there is no recovering them. According to the ETTR function in Magic Lantern, they recommend -.05 or -1.0 when exposing to the right. 

Your Flatz is interesting but how does it differ or perhaps what are the advantages of using it instead of Technicolor Cinestyle?
Have you reinvented the wheel or am I missing something?

I've gotten pleasing results using the free Cinestyle which loads as a picture style into the Canon cameras and then using Davinci Resolve.  Have you done any comparisons?  I will give Flatz try and I appreciate your efforts at improving raw workflow results.

Unless I'm mistaken, Picture Styles in camera do nothing to the RAW video because it's RAW and White Balance, Contrast and other related metadata is not baked.

My preset is a Adobe Camera RAW preset which captures the full range of dynamic range into whatever format you choose to render into.

Cinestyle is restricted by the H.264 codec, the 8bit space, and the fact that you only get about 9 stops of dynamic range.

D.L.Watson  - thanks a lot for making this preset! I´m just wonderin how you retain the highlights with the highligts slider in ACR in the middle - so there´s still room to pack more dynamic range into the preset, right?

With my initial tests I was not able to re-grade (in After Effects) the look that I would do straight away out of ACR "as the eye saw it". Your preset comes close to a LOG-look (like ProRes 10bit log) but of course a normal cineon-converter effect in AFX brings out some funky highlights since it´s not really log - could you provide some presets/nodes (After Effects, maybe Premiere with its fast-filters, Resolve) on what your way would be to grade the footage "normally"? Starting from there one can still make us of the dynamic range in the file to make on changes.

Thanks a lot!!

Hey there SteveScout. Highlights and shadow details are retained by using a tone curve in Adobe Camera RAW. The sliders are left default at zero for individual customization - but in my own use, I have not needed to touch them.

I wouldn't recommend a Cineon Converter - but that's also because I've never used it before. If I were to color in After Effects, I would use Colorista II or just simply a Levels Adjustment and boost saturation.


RAW at the default settings. Exposed to the right.


After applying the preset in Adobe Camera RAW


Adding some contrast and saturation.

hey can u explane this thing? im interested
what is flatz preset? is it just to make flat unsaturared picture for color grading?
i know u apply it in adobe camera raw in after effects import of dng files
but do you need to apply it to every frame or to sequence?

and why my after effects doesn't have output formats such ad DNxHD
maybe i have to update it?

and what is it unique about da vinci and why use it?
i mean can u suggest after effects plug in alternative to work with your flatz preset

also i cant even export to prores 4444 or anything...

my adobe cs6 is kinda empty...

this is what ive got after using your preset
btw this i did on 640 by 240 resolution raw on canon 50d on iso 1600 or so...
coz i wanted to test raw video on old compact flash card from kingston
it is speed around 6 mb/sec  24fps
compared to my other card which is lexar x1000 55 mb/sec
that can record something around 1585 by 900 or more



not so bad for 6 mb/sec 24fps raw recording isnt it?

Hey there Silkway.

I'm not sure why your image is cast green - there must be a white balance issue. The preset does not affect your white balance - that you must set yourself using the eye drop tool in ACR.

The flatz preset does not manipulate saturation - it uses tonemapping to get as much detail out of your shadows and highlights to be able to render to a more manageable file format for grading. You apply it to a sequence, but you can also use Bridge to apply it to all of your DNG's at once if you prefer.

To get the DNxHD file formats, you need to download them from AVID here: http://avid.force.com/pkb/articles/en_US/Compatibility/en350875

Davinci is a powerful industry standard color correction software. Naturally, I prefer it for professional work. Unlike Adobe AE, it provides you with a RGB Parade to see if your grades/colors are broadcast legal.

Here is a workflow video I did quickly covering the basics of this preset:

So, I'm loving the Tragic Build. Great work there guys.

Also, pulled out that cheap nifty fifty to check it's sharpness at 3x crop mode. Absolutely sharp. What a great lens! This is a still from 2K footage at 3x crop. Of course, I used my Flatz Preset to render out a DNxHD and grade in resolve. No post sharpening added. You can download that here: www.dlwatson.net/flatz-preset.html

Updated the Preset to V2.2.

* Fixed a bug where image would invert if exposed to the right (which you should do)

Download it here: http://www.dlwatson.net/flatz-preset.html

Also, please, if you download the preset, let me know how its working for you. I'm open to your thoughts, criticisms, and suggestions. Thanks!

I guessed which was which correctly. The reason being, the flatz profile looked... flatter.
I believe a little contrast added would have not allowed me to notice the difference.

Exactly. I had forgotten that I had turned off my contrast and sharpness node in resolve until nearly finished with the video. I still believe it illustrates that you still have all the same amount of dynamic freedom to grade the image and save space. But to each his/her own.

DL did you not add sharpness in Resolve and/or do you simply prefer the flatter look?

Yeah, I forgot turn back on my contrast and sharpness node. And personally, I do like a contrasty image, but without sacrificing highlights and shadow detail.
