MLVProducer: [v3200]

[Thobias]

Is it possible to export to DNG files?

[AWPStar]

@Thobias

dng contains raw data. there is no reason to use this app, if you want to save your footage to raw. i can use mlv_bump to extract dng's, but what's the point?

[Thobias]

Point is to get nice feature of reducing pink dots and other graphic glitches and still be able to edit RAW files in Premiere or After Effects. I'm simply not able to export every scenes for final cut. I have to cuts scenes and then apply colour grading. But maybe I just have wrong workflow.

@AWPStar
A lot of ML users need raw first.
Every existent software for extract DNG from MLV has it's drawbacks and there is no ideal solution (at least on windows):
mlv_dump - wrong WB, no CDNG - no timecode, auto audio sync in Resolve and so on. Yes, and this is console application
MlRawViewer - same as mlv_dump regarding DNG export, have GUI, but abandoned
raw2cdng - abandoned, buggy, didn't extract all the metadata (lens info for example) but with correct WB
MLVFS - windows port abandoned
So, you have the chance to make the best tool

@AWPStar, i fully agree with mothaibaphoto.
In my latest workflow i often use MLrawviewer just to select couple of seconds out of a much longer footage, than i can delete original, huge MLV and still have raw (extracted DNGs). MLrawviewer is abandoned and unfortunatelly lacks of CDNG. Could you implement extracting MLV to CDNG with in/out points? This with your existing UI would be a killer feature for me.

Is it possible to open the next clip from the folder by just pressing a button?

[AWPStar]

@kgv5
Yes, but from the queue. Ctrl+PgUp/PgDown

Very impressive App ! But I one thing missing, Is to Export to Cdng's I thing this a must , That what keeps me from using it .
It really pointless to export to a FFmpeg ProRes 10 bit file (Specially 444) To much Clipping in the low & highs , unless you can
access the QT Codec Without FFmpeg. The Only Codec to date that can handle the full range of ML raw is ProRes 4444XQ which is a only MAC thing.
But since your app can run in OSX with some help , I would be nice to access the QT Library path and I think in PC if you got access to the QT Codec
"C:\Program Files (x86)\QuickTime\QTSystem" like the QuickTimeH264.qtx,etc.... then any QT codec installed e.g. SheerVideo Pro.qtx ,BlackmagicRGB.qtx which are installed on my PC & MAC
can be used. But I think it would easier to just export Cdng and transcode to .mov or .avi with standalone different Apps.

Just my thoughts on the matter 
What ever you do it still amazing App , keep up the great work !

[nikfreak]

I clicked on remove focus dots (add pixel) and then some squares came up and after that I clicked on the "+" for pattern shift and the app crashed wit a runtime error 
But looks goof so far. I am impressed. keep up the good work.

Ability to have access to the next clips from the folder without having to import them on the first place would be very nice. Like in MLrawviewer where you just selecting a folder from a browser and than press a button and the next (or previous) clip opens (of course its doing this indexing thing first). Could you implement some kind of browser with thumbnails? My workflow now is mostly to insert memory card and select clip fragments with in/out points instantly switching between files. So than I have "filtered" DNG sequences which saves me a lot of hdd space and i can still do everything with them. So thats why we need CDNGs to have ability to easy sync the sound in resolve but still have raw.Of course having option to render clips as proxy files with your app is great. I am still afraid of render movie clips even in good codec and delete raw. Keeping raw at least to the moment when the whole movie is ready is essential to me.

[DeafEyeJedi]

Agreed w @reddeercity regarding QT codec especially PR4444XQ to get the most out of ML Raw.

This app runs well on my Mac's under Wine and it definitely looks promising!

For now i probably can handle with uncompressed 16bit cdng.
But it will take more disk space than MLV-file as cdng doesn't support 14bit mode. Only 8,10,12,16.

[Danne]

Have you checked the compression of cdng files in mlrawviewer? Might be something useful regarding size.

[AWPStar]

@Danne
I began to understand the structure of DNG(tiff)-format.
And as i understand the MLRV code, it doen't use compression too.
I'll try to implement deflate or LZW compression.

Andrew Baldwin wrote something about the compression method he used for MLRawviewer here:

It would be great if you could implement 16 bit cdngs.

@kgv5 @DeafEyeJedi @reddeercity @Thobias @mothaibaphoto
You have convinced me. I will implement it. But it will take a long time.

Then you will have most powerful tool for RAW video enthusiastic creators! I made my day, dude=) Thanks!

[DeafEyeJedi]

It'll be worth the wait. No rush on this!

[AWPStar]

I just saved my first cdng. And opened with AE =)
If you know tiff/dng/cdng Tags that must be implemented - pls tell me.

[Danne]

That was fast work

From row 72-165
from row 700-754
Notice that dmilligan calculates the correct wb as well. MLV files contains kelvin and rgb info. I think he,s referring to ufraw calculations when getting wb.
Stretched files. Slowmo also gets the "default scale tag" which unstretched(regular) files won,t have.

@Danne

Also dng specification
http://www.adobe.com/content/dam/Adobe/en/products/photoshop/pdfs/dng_spec_1.4.0.0.pdf#page19

I don't want to implement all of DNG-tags. Most of them is useless because MLV doesn't contains some information.

Solved this problem.

[AWPStar]

That's what i got.
http://s1.postimg.org/vqsu14z2n/testwb2.jpg
i think it is pretty correct WB.


Another good news!
Deflate is working! 2766643 Bytes -> 898402 Bytes against 1747468 of MLRawViewer

[Danne]

Looks real nice. Is it adopting camera wb or are you using some kind of auto wb?

About dng tag spec. Feel free to adopt any tags you like. It, s your application .

[AWPStar]

@Danne
just fixed values.

[AWPStar]

Can anyone check this DNG in Davinci Resolve?
