Post-processing Workflow / 3D Lut to ICC
« on: February 05, 2017, 11:47:25 PM »

I was wondering if you are familiar with 3d lut to ICC profile to view frames in other image viewers.

I would like to convert this LUT (K_TONE Vintage_KODACHROME.cube) to ICC and assign it to the image: (external link)

Is there a way to convert a 3D LUT to a ICC profile?

Those apps work great with nativa raw footage. What if I want to convert a CR2 file from a Canon Camera? It still is a Raw that I want to convert to a single cinemati DNG.

How would you go about that?


PS: I just want to try and post produce still images in Resolve by applying some log curve to it.

It depends on how you scan the negatives. You could just save the scans to cineon files or DPX. Saving as DNG could add bayer artifacts unless it's demosaiced DNG (basically a TIFF). Cinelog is based on Cineon which is a log encoding/representation of film print density but built for a linear digital negative source

The scanner I use can't either save to cineon nor dpx files. Its raw scans are linear, and I'm able to save them as tiff or dng files. So, all in all its a linear digital negative source. Could I ingest Resolve with these raw scans and apply a bmd-to-cinelog input lut?

I wonder if I can use this log profile in anyway with negative film (medium format) scanned. I would love to batain somethibng similar to cineon where the data is stored in log format, directly corresponding to density of the original negative. Because raw scan are linear I might be able to save them as tif or dng files and then apply the Cinelog profile. The color correction would take place in Resolve.

Why not just regular 16-bit no smoothing? It works great.

Could be that on some shoots the lens does not seem to be focused on infinity (moments before the tunnel)?

Do you think with a wide lens like that the DoF will stay almost the same no matter the aperture?

That means I might be better off NDing the lens to capitalize on its sweetest spot (around f/5.6) instead of stopping it down adn get diffraction.

VLC Player to play almost any video file.

How much would Resolve help here?

A lot. I would set Vision Log as a 3D input lut on Resolve and then color grade the DNGs. Also, transcoding into pr444 with a baked-in log curve is time consuming under MlRawViewer. Resolve is a piece of software defenitely worthwhile getting one's head around. I'd suggest using raw2cdng instead of MlRawViewer.

Come to think of it I can set TC to 00:00:00:00 on Resolve. Everything is ok now.

I would like the "start TC" to be always 00:00:00:00 instead of the date of the day (that's what I see on Resolve).

I would love the folder to be named M22-1852_DNG_000001 instead of M22-1852 and the files inside something like M22-1852_000001 instead of M22-1852000001

(first 2 clips generated by raw2cdng, last 2 clips generated by MlRawViewer)

After all, I like raw2cndg for its batchlist properties!


Do you move the glidecam closer/further to change the focus or you had some sort of follow focus?

I have just found out the beauty of working with offline h.264 proxy files. Mine are set to Keyframe every 1 frame and medium quality. How about yours?

I see this orange/teel look is still all the rage! Did you have a log input lut also?

Love how the contrast came out and the colors are beautiful... I think you made the right choice by decreasing the opacity of the M-31 LUT to 50-60% allowing the REC.709 to still be shown noticeable.

How can I low the opacity of a LUT?

I was wondering when it comes to those BMD Film to log luts, if I should use the Log Controls in Resolve instead fo the Primaries; based on the film timing approach, in that, to use a combination of exposure implemented as offset in Resolve and contrast to alter the color balance and overall level on the image. Can the Cinelog-C be compared to the standard Cineon type log curve?

I am asking this because I believe the Log Controls in Resolve may have been designed to be used with standard Cineon type log curves.

I think 16 hours for the converting process is a lot. Also, I don't see the use of DNxHD which renders everything to its own chosen template dimensions. Yet, if it is crucial sto stay on adobe there's no other workflow I can think of.

My view is you don't really cut the raw, you convert it to Pro Res or something that you can edit just fine, go back to the raw to color, then master. So, I'd import RAW to Resolve, create proxy for editing, edit proxy, send edit to resolve, grade RAW.

Raw Video / H264 from ML Raw for offline editing
« on: April 26, 2015, 07:07:16 PM »

   I am on Resolve under Win7 and am looking for the best workflow to get editable proxies from ML raw. Since I don't have ProRes 422 (proxy) on this platform I was wondering if H264 I-frame only could be decent to do the editing.

Here is how I would do the rendering to obtain editable h264 proxy files:

Render timeline as: individual source clips
Video Format: QuickTime
Codec: H.264
Comp Quality: Best
Data Rate: Automatic
Key Frames: Every 1 frames
Frame reordering: off
Field rendering: off
Render unique filenames: off
Force sizing to highest quality: yes
Force debayer resolution to highest quality: yes
Enable flat pass: off

I don't seem to find other formats and codes under Resolve except maybe for DNxHD which would take a lot of space though.

Any suggests?


What is the difference between MlRawViewer and raw2cdng when it comes to get DNG sequences?

So, how do you use the VisonLOG lut on Resolve? Do you use it as an input lut from BMD color space on DNG sequences or do you apply it as a 3D output lut to get a very flat high-dynamic-range look and then let Resolve output ProRes that can be sent to the editor.?

Also, when dealing with DNG sequences how do you set the "master settings" in "camera raw" on Resolve?

Mine are:

Decode quality: Use Project Settings (I see some set it to full res, why?)
Decode using: Clip
White bal: as shot
Color space and gamma: BMD Film
Highlight recovery

I've read about formatting the compact flash as exFat on the PC instead of fat32. This way files won't be broken into 4gb chunks.

I must admit I got a 16Gb 800x. Is it even slower? I am returnig this cf card and getting with a SanDisk instead. Now I see why the Sandisk 60 MB/s is twice as much the Lexar 800x other things being equal.

I got a Lexar 800x thinking it would outperform the SanDisk Extreme 60 MB/s. Yet, I am still stuck at 48 MB/s. Am I doing something wrong? The Lexar is supposed to go way faster then the SanDisk.


Once you have your DNG sequence:

- convert to video. Not only for editing but also to playback and catalog your clips.

Why not doing the editing from DNG sequences? Converting (transcoding) RAW to video for editing takes a lot of time and a log curve is to be choosen. Mlrawviewer can convert RAW footage (5 mins) into DNG sequences in a flash.

I am on Resolve and it can handle DNG sequences just fine. I assume other softwares can do that just as fine.

I don't see what makes ProRes 444 (S-log) better then DNG sequences for editing.

Also, is ISO 80 (equivalent iso 100, analog iso 100 and ML digital ISO -0.3 EV) for h264 only or for RAW also?

5D2 Dose 30p just Fine! , Just not Continuous Like 24p @ Max resolution

In Canon firmware I set Movie Rec. size to 1920x1080 25fps in liveview/movie funct tab. In ML I set 1600x680 at 2.35:1 and FPS override to 30 (optimize for exact FPS). Yet, the actual FPS is 27.173 how can I get it to 30fps?

Come to think of it, too bad I can's shoot at 30fps on the 5d2 (max is 27 or something)

   I want to set ISO to 160 in ML. Yet, canon analog iso only goes from 100 to 200 while the the canon digital iso does -0.3 EV (subtract). So, although I set 160, on the viewfinders it reads 200 ISO. What's the problem? I'm on the 5d2.
