Fast CinemaDNG Processor application allows to view DNG image series recorded with video and photo cameras.
The software can do standard image processing of RAW DNG and CinemaDNG files on NVIDIA GPU in realtime.
We currently support the following DNG (RAW) formats and compression options:
Uncompressed DNG.
DNG with lossless compression. It has zero loss of detail, but quite small compression, just around
35% file size reduction for very blurry / underexposed / overexposed images ranging to around 25%
file size reduction for well focused, well exposed, detailed images.
BMD RAW 3:1 compressed lossy DNG. Some image detail are lost, but not much. The compression is
usually rate controlled to 3:1, so recording capacities of media are very predictable.
BMD RAW 4:1 compressed lossy DNG. This is the same as 3:1, but with better compression. The
quality is still good, but not as good as 3:1.
The following 3 modes (three DNG formats) are currently offered with BlackMagic URSA:
Losslessly Compressed RAW
Visually Lossless 3:1 RAW (lossy)
Visually Lossless 4:1 RAW (lossy)
Very interesting App , Wins only looks like and in beta so free , Like Beer
It's basically a Grading app for dallies or what ever on Raw Cdng Uses Cuda
real time noise reduction !Very nice
you can grade your MLV Raw and export as Cdng's !!
DNG export tab contains parameter, used to render project into DNG. Currently only compression and crop are supported.
Supported compression algorythms are:program directory.
Use original. In this mode project files are simply copyed despite of crop settings
Lossless JPEG. In this mode raw data are compressed with losseless jpeg algorythm.
BMD RAW 3:1. In this mode raw data are compressed with lossy BMD RAW 3:1 algorythm, designed byBlackmagic Design.
BMD RAW 4:1. In this mode raw data are compressed with lossy BMD RAW 4:1 algorythm, designed byBlackmagic Design
BMD RAW 5:1. In this mode raw data are compressed with lossy BMD RAW 5:1 algorythm, designed byBlackmagic Design
I did a quick test with 12 bit mlv+audio from MLVFS quick mount with fuse . Seem to work OK and debayed correctly.
Lots of camera raw adjusts to work with , Does take a fairly beefy machine to run
Tested on my over clock FX8350 (4.9 ghz) on dual GTX 580 cards 3GB Vram with 8TB Raid "0" OS on SSD
It seems to labour a little thou my Vid card are really out dated , there recommend at least "GTX 980TI, 1080 or Tesla K40 GPU memory 4-12 GB"
You also have a option for Working Color Space , e.g. sRGB , Adobe , etc... lots of professional stuff
So it seems it's was intended for Blackmagic Camera up to 8K , I highly recommend trying this out even if it's to convert your ML Cdng's to BDM raw3:1 to save space
plus you can have a grade applied or just leave in film log space , exports with FFmpeg , Cdng's , Tiff . I Can see this app costing big $$$$ later down the road .
So don't loose out .
Edit:
I tested the compressed .dng export , original cdng from mlvfs was 1856x1044 3.75MB & the compressed dng is 1.29MB used the lossless jpeg compression
I can't tell the difference , here a link to each dng frame from my dropbox .
lossless_jpeg.dng original ml dng Also tried 3:1 which gave me a frame size of 133KB
The only thing I see there's no frame rate tag but all other tag are pass though ,
exiftool tell me the 3:1 is 12bit with jpeg compression and the lossless is 16bits with jpeg compression and there again no frame rate tag .
