I am a bit uncertain which of my two workflows are better in term of optimizing the picture quality and retain as much detail as possible.

Workflow 1

Using v.1.4.3 apply log-c and the 3D luts osiris M31-log32 export to cDNG
Import i Lr for complete color correction/grading.
Import in AE and apply osiris M31-Rec.709_32 (not 100% opacity but less)

Workflow 2

Using v.1.4.3 apply log-c export to cDNG
Import i Lr, apply visionlog and a full color correction/grading.
Import in AE and apply first osiris M31-log32 and then osiris M31-Rec.709_32 (not 100% opacity but less)

I've read that one cannot apply two logs after another (log-C and then visionlog). Is this true? If so does it imply that workflow 1 is the best approach?

Does MLRawViewer deteriorate quality after conversion?

For some reason I feel like that.

Conversion to what? Define "quality". Post examples. Describe your workflow. We care about facts not feelings.

Thanks for your response.

My work flow is MLV to Premiere.

By feeling I meant visual generation loss.

But today I felt much enhancement using MLVP to Camera Raw to Premiere.

Got this output https://www.youtube.com/watch?v=s8cYkzNSD3o

Because I have been fighting with pink frames and extended noise. Does it have to do anything with settings or just MLV could be the reason?

Also I felt much improvement in quality after using MLV 1.4.3 so is there any reality attached or facts to back up?
I don't know how to quantify pixellation in figures.

What is the standards workflow for the best visual treat or output or least drop so to say.

Thanks again.

@dratif I can't understand why you are using old outdate ( not to mention very time consuming) workflow .
The quickest and yet the most precise workflow has always been MLVFS (cdng on the fly convertor) http://www.magiclantern.fm/forum/index.php?topic=13152.0
Cross platform (PC & Mac) Just mount the MLV and import Cdng in to Premiere Pro or BM Resolve no need to waste time converting .
This is the Gold Standard for file extraction . A trusted professional workflow I can be working with ML raw file with correct audio sync in least then 2min in resolve.
Important to my workflow as I need quick turn around , I do mainly news/documentaries pieces.
Or the other amazing fast raw workflow in which you can fully grade your MLV or Raw ver. 1.0  files and export as a ProRes , DNxHD , Tiff , Png's , H264  and of course Cdng's  then try out
MLVProducer http://www.magiclantern.fm/forum/index.php?topic=15271.0  Originally it's a PC app but will run under Wine in Mac OSX
This post explains how get MLVProducer working with Wine in OSX  http://www.magiclantern.fm/forum/index.php?topic=15271.msg151403#msg151403

And from my understanding MLRawViewer exports lossless JPEG Compressed DNG's read the following posts

Indeed I used MLVFS for the above video.

I will study and will bother you again in case I am lost.

Thanks a bunch.

(The log grows very quickly; it seems that division by zero error occurs when trying to decode every frame.)

1.4.3 looks pretty much the same. It does show a right thumbnail image after launching, but then falls into black screen again with similar log records:

My issue has been fixed spontaneously after updating video drivers (nVidia K2000D).

I want convert over 100 RAW files to MOV with Log-C. Is it possible to do it in bulk or I have to do it separately? Thanks.

Place .MLV files you want to convert in a separate folder named by exemple "batch"

Choose this folder in MLRAWviewer, make your settings and destination folder, and press C for a batch processing.

Hi,

I'm having a problem where MLRAW Viewer repeatedly crashes on me while exporting. I've tried all the versions and they keep crashing. My laptop hardware is more than enough to handle. I'm on Windows 10 and have a ASUS ROG GL752:

Someone please help me!

Does anybody know how can I apply the exact same look MlRawViewer S-Log2 curve has to ML raw CDNG files imported in Premiere Pro?
I tried downloading .cube files from MlRawViewer but it produces a washed out white image, nothing similar to image I see when I play the video in MlRawViewer.

Roberto Mena

zonapg3, I had kind of a similar issue, what worked for me was to move or copy my RAW (MLV) files from my CF card to my hard drive and export from there using mlviewer and for some reason that worked.

zonapg3

Hey Roberto,

I'm exporting from an external hard drive. I've tried moving the files to my laptop drive and exporting and still experiences the same problem. I've tried multiple builds and they all have this crashing issue. Is this something that struggles with windows 10 or maybe this specific laptop. My computer has more than enough firepower to handle these files so I'm baffled.

This is old and unfortunately unmaintained.

Did you try MLVFS already? It's on active development: http://www.magiclantern.fm/forum/index.php?topic=13152.0

Steve_Brule

I click on the app, it blinks and asks me to select an MLV file, which I do ... and then nothing happens. I see the process in task manager ( windows 10), and it's chugging away, but nothing ever shows up on screen.  Is there a trick?


-Rogue5-

Pushing Shift+3 to unload the current LUT doesn't seem to be working...  Is there another way to remove loaded LUTs?


Conversely, would it also be possible to increase the number of LUT slots to 12 or something more than 2?

You should really think about using either MLVFS, Raw2CDNG or MLVProducer which are all very good options.

Mlvfs is great for going into resolve but this would still be cool to have working in 10 bit 12 bit for quick playback without having to render..
