Natron's ReadOIIO can read CinemaDNG. I see it uses OpenImageIO for that. So does it make sense to use Natron command line as the way to transcode CinemaDNG to a format suitable for offline editing? Or is Natron not really meant for that, and a different tool should be used? The Python bindings for OpenImageIO?
Hi,Did you succeed reading DNG sequence in Natron ? I'm asking because I didn't. The sequence we took with a Blackmagic URSA Mini appear all black. With a ReadOIIO node I can't see nothing. Only DaVinci Resolve could read it to transcode in another format. If you have any advice...
Yes its from Blackmagic Production 4K Camera. It plays fine in Natron.
Ok but how ? Can you be more specific? With the standart readOIIO you did? on wich plateform ?I'm using version 2.0.2 on Windows 7 64bitThancks for your help
Just standard ReadOIIO it works straight away. From various versions of Natron, including 2.0, 2.01, 2.02, 2.03. On OSX and on Linux.
Thank you nickcarroll.I tested with those test footages and it worked : http://video.blackmagicdesign.com/Shot_1.zipBut not with our own : https://we.tl/yg7MbmJmW8
Maybe there is a difference between them (in recording) that I don't understand
Blackmagic URSA support was added in libraw 0.18, we don't use that version yet.
Hey ramellij checkout the trial version of this utility: http://www.slimraw.com/faq.htmlProcess your footage with this and see if it can the appear in Natron.
Thanks nickcarroll I will try
You can use Dave Coffin's dcraw to convert the URSA DNG files to TIFF for Natron:dcraw -w -T *.dng
Libraw 0.18 is currently in beta(3) and will probably be included in the next Natron release (2.2).
LibRaw 0.18 supports:- BlackMagic Micro Cinema Camera, URSA Mini- BlackMagic URSA- BlackMagic Pocket Cinema Camera, Production Camera 4k
Hello,Do you have any news about that feature ?
Libraw 0.18 is now marked stable. I will test the new version this week and upgrade if nothing breaks. Then Natron will/should support:
Hi,Any news about the integration of the last stable Libraw 0.18 ?
libraw 0.18.1 will be in the next Natron patch release (2.2.6)I also added options to control a few libraw options (such as the demosaic algorithm)
If you're on macOS, you're lucky: you can try the latest snapshot.If not, you will have to wait until we upgrade libraw on other systems
