That’s what many have been doing already. You can stop at this stage and just use the resulting DNG sequences. Everything is either left unchecked or set to None.
DNG Converter will recursively process any subfolders and compress sequences.Īdobe DNG Converter Preferences for losslessly compressing DNG video. You specify a source folder containing the DNG footage and a destination folder for output make sure that on the Preferences screen “JPEG Preview” is set to None and “Use Lossy Compression” is unchecked then press Convert. Adobe DNG Converter is straightforward to use for processing DNG video sequences. Since Adobe spec’d the DNG standard, it isn’t surprising they provide an application that can compress DNG images.
Both are free to use and available for Windows and Mac OS X. There are a couple of applications involved in the process. So you start with uncompressed raw DNG/CinemaDNG sequences and end up with losslessly compressed raw DNG sequences. Both Adobe Camera Raw and Blackmagic Design DaVinci Resolve 10+ support losslessly compressed DNG images. In fact, that is exactly the compression format used in compressed DNG video produced by the Blackmagic Design Pocket Cinema Camera. Key here is that the DNG standard provides for losslessly compressed DNG frames. Lossless means truly lossless: pixels are exactly the same as in the uncompressed file. Note that by lossless I don’t mean visually lossless. All of these would benefit from some kind of (lossless) compression.
Update April 2015: I now have a much better solution for CinemaDNG/DNG lossless compression, which solves all the issues mentioned here.Ĭurrently there are a quite a lot of cameras that shoot uncompressed raw DNG/CinemaDNG video, or processes which end up with DNG video sequences: Blackmagic Design Cinema Camera, Digital Bolex, Ikonoskop A-Cam DII, Kinefinity first generation cameras, Canon Magic Lantern raw video, Sony FS700 + Convergent Design Odyssey 7Q, etc. Lossless DNG compression allows a reduction in video file size while preserving all the benefits of a raw post workflow. This article describes an alternative simple workflow for lossless compression of DNG/CinemaDNG video footage, and also introduces DNGStrip – an utility that’s used to optimize file size. The downside of this approach is that a bit of image integrity and re-processing options are ultimately sacrificed in lossy compression, which is not exactly the goal of optimal archiving and image quality. One way of handling the size problem in post-production is to do some initial adjustments on the raw video, then bake to a lossily compressed format like ProRes, DNxHD or Cineform and only keep the compressed video for further post and/or archiving of the source material. Uncompressed raw video can quickly add up and fill storage.
I can't be without my editing software as I need it for some work files.There are a lot of good things about raw video but data size is not amongst them. I though for the time being I could use the DNG converter, but as far as I can see, this needs Mac OS 10.11 or later so if I do that my PSE13 won't work. I've considered Elements 2018, and this needs Mac OS to be 10.11-10.13.
If I upgrade my operating system, PSE13 won't work. There is an upgrade available to OS High Sierra 10.13.3.Įverything was working just fine until I bought the OM-D EM1 II, but I can't import the raw files due to them not being compatible with PSE13. I'm using PS Elements 13 - this is only compatible upto camera raw Ver 9.0 and needs MAC OS V10.8 through 10.10. Olympus OM-D E-M1 Mark II - needs camera raw minimum of 9.9 Olympus OM-D E-M5 Mark II - needs camera raw minimum of 9.0 I'm hoping someone can help me as I can't get my head around what I need to do re getting all my software and files to be compatible with one another.Ĭanon EOS 70D - Needs camera raw minimum of 8.2
