hi.. sometimes my footage does not play in MLRawViewer, the screen is fully black, I thought its a mistake and proceeded to convert the .raw to cdngs. The converter shows "0 FPS" and crashes. Is that footage a shooting mistake? i don't think so bcos other footage is good. Am I wrong at something? Why would that happen? (the take I okay-ed is unfortunately showing this error  :-[)

@chmee: Any news about the vertical banding (fixed pattern noise)? I've shot a lot 50p footage and the banding is pretty bad. So I have to convert MLV's to RAW's, then export dngs  with raw2dng and then have to edit the exif camera model with irfanview batch for ACR -- very slow and complicated process. It would help a lot if you'll have a time to implement FPN correction. 0:-)

..because i went to an x/y-view to the data (instead of simple array rewriting) theres a good chance to implement anti-banding and cs.

@chmee,

does the new fix in raw2dng have any effect on your raw2cdg app?

A1ex fixed a bug posted here;

can someone explain why in after effects is so slower playback of dng?
in davinci i got around 10-15 fps.
in adobe 0.5 i think i even can't scrub trough

apart from the fact that after effects in general is slower (its a compositing software, not a clip-based edit tool), dng is imported by a slow, but high-quality onTheFly-converter (acr).

please be patient, i'm gathering all experiences, fixing and optimizing raw2cdng. there was work as well (echo2014 award) https://www.flickr.com/photos/chmee/

@ted will have a look on it. i never saw this kind of artifacts..

regards chmee

Is there a way to get rid of vertical noise with this app? I dont get vertical noise in raw2dng but I do in raw2cdng

yeah I'm also having those vertical banding issues.

There's another app (mystic) which has a fix for it, just check the function and bang, problem solved. Perhaps something like it on raw2cdng?

Thanks chmee for the lovely job on this software!

i described it above. to solve vertical banding or deadpixels you have to look on it as a picture (x/y-pixels) not as an array of bytes. i'm on it, but i guarantee, the conversion will slow down. thus it will be an optional button..

(still recoding) regards chmee

by the way. we'll see what advantages the next CC-Version will bring (NAB2014) - maybe the whole work is not needed anymore :)

Still lot of people use CS6 and I think this is the Canon raw from C500, not ML. But we'll see :)

i do not count on the canonRAW-entry in the video, but on optimizing/opening the raw-module. thats all i want :) (but yes, i think about converting ml_raw to arriraw or canonraw, but these tests will come after the recode of raw2cdng). After that (middle of 2017) think i'll find the time to read the CC-sdk to write an native importer :D

The forthcoming release of Premiere Pro CC and Media Encoder CC will support *some* types of ML-generated CinemaDNG footage but not all, and they have to be real cDNG frames not just a folder of 'stills'. I can't give a detailed matrix yet as the code is still in flux, for example the build I'm testing now has problems with stuff from the 7D and won't read 14-bit files.

... by the way, if folks want me to run a test on a particular 'flavor' of cDNGs, upload them someplace and ping me a link. Don't need more than a second's worth of frames.

Hi DFM,
I use MlRawViewer to export cdng, it opens really good when i import to pp cc and use direct link to speedgrade. but when i import straight to speedgrade it has heavy green cast.
Does the new version has solution to this issue?

For Speedgrade you should build your own Matrix or LUT - i made a Matrix-example in raw2cdng 1.4.5. Use this one or tweak the Matrix, and write them into the file i provided. thats not a real issue.

btw. did @baldand solved the pink-highlight-problems?

Sg in the current version of CC expects slightly different things in footage; DNGs in the other apps previously went through Camera Raw but in the forthcoming version they import natively, and you don't get the ACR dialog if you open the cDNG footage's "source settings" - instead there's a Lumetri quick-adjust tool. That will impact on workflows that use the ACR engine to do heavy lifting (lens corrections, noise reduction, etc).

Here's the dialog being fed a 16-bit linear cDNG from chmee's app:

Thanks chmee i will look for your example, even when i fix the green cast it looks like there is no highlight information to work with.

Regard baldand MlrawViewer,  on pp cc only saw them once at high contrast areas.

Looks good. It's a start... i guess.

@DFM thanks for the insight - looks like the arriraw-settings window :)

@DavidSh you're welcome

@baldand had an issue entry on bitbucket about pink highlights. i emphasize his opinion, we have to wait for the next CC-Version. my actual fix is not the ideal solution.

Unfortunately not. I'm still hoping Adobe solve this in the next version of PP since it's clearly their issue.

Hi all , there a new update to premiere pro today at least to me. Version CC 7.2.2(33)
I guess with NAB 2014 now in full swing there was bound to be some updates .
Anyways I was trying some cdngs and at least to me it the closes I have seen yet.
I used raw2cdng Version 1.4.9 with 12bit party mode gamma1 it looks right.
With 16bit its still pink hi-lights, so looks like improvement for 12bit , if someone could verify
this the would be great . :)

With the forthcoming versions, 'party mode' isn't required anymore. The screenshot I posted earlier isn't of a 'party mode' file.
