CineformRAW as Intermediate, Interchange and Archive Format for RAW (CinemaDNG) from BMCC

Saturday, March 22nd, 2014

Following on from where basically I discovered that

  • you need not only GoPro Studio Premium (which gets you the CineformRAW codec) but also a little front-end utility (that you use instead of Studio Premium) called RAW4Pro.  That utility gets you the correct colours and proper audio (‘Studio’ does not otherwise).

Using that solution, I obtained a 5.5 times reduction in file size, for a few-seconds test-clip where the color-chart was handheld against the landscape at the top of the hill.  The file looked good in Resolve where I was able to grade it ok and of course could have used it to encode MOV-H264.

Equally the CineformRAW imported fine to Sony Vegas Pro 12, where I could grade it and export to MP4-H264 or whatever.  Vegas did not recognize the original RAW (CinemaDNG) – I tried various ways, including Vegas’s Device Explorer, so CineformRAW is a useful workaround for this.

The CineformRAW generated by RAW4Pro in its [Fine] setting, according to its [?] button, produces 10-bit Log, which QuickTime player reports as as “Millions+”.  I wonder, is there a way to get it to produce 12-bit?

I expect I will use CineformRAW to replace my existing RAW footage where I want to maintain full 2.5K resolution, gradeability but don’t have chromakey-level demands on resolution around edges etc.  Not that I’ve yet tried such chromakeying, RAW or CineformRAW -based.  As yet…

RAW CinemaDNG (from BMCC) to CIneformRAW for DaVinci Resolve via RAW4Pro+CIneform

Saturday, March 22nd, 2014

Suppose you have some RAW footage, in CinemaDNG format (a number-sequenced set of [.dng] files), for example shot on a Blackmagic Cinema Camera (BMCC).  Compared to “visually lossless” say ProRes or DNxHD (let alone H264 etc.), CinemaDNG occupies an awful lot of disk space, primarily because it is mathematically lossless.  The GoPro-CineformRAW encoding format offers significant reductions in file size (and hence data rate) at the cost of a practically negligible loss of visual information (and a purchase price).  This codec can be purchased as part of the GoPro Studio Premium product.  A comparison-grid of the various GoPro Studio products is here.

CineformRAW is an attractive compression-format, but unless care is applied to some very technical-level encoding options/settings, compatibility problems can arise when importing to DaVinci Resolve.  The latter is in widespread use but is especially relevant to BMCC owners because it is supplied as free software with that camera.  I experienced such problems myself: one version of Resolve (v.10.0) interpreted CineformRAW clips as green-tinted, while another (v.10.1) just gave black frames.

Happily, a simple solution existed: RAW4Pro, which is essentially a front-end to CineformRAW (and also to DNxHD, useful e.g. if you want HD proxies).


  • Install
    • A product incorporating the GoPro-Cineform RAW codec.
    • The RAW4Pro utility
      • Essentially a front-end to generate CineformRAW and also to generate HD (e.g. as proxies) as DNxHD, in each case in either MOV or AVI container-formats.
  • Run RAW4Pro
    • Select (Browse-to) input-folder, output folder.
    • Select:
      • Sound: Audio-Merge
        • Initially, extract audio from source file to a WAV file, then merge this audio in with the generated file.  The WAV file remains, regardless.
        • The alternative (if not enabled) is no audio in the generated file (and no WAV file).
      • Processing: Convert-Only
      • Quality: Fine
        • Clicking the [?] button reveals that this creates 10-bit Log (colour-channel resolution).
      • Video Format:
        • Cineform RAW (encoding format)
        • MOV (container format)
        • LUT: NoneClick the [Process Clip] button.
  • Result:
    • A movie file with name prefixed by :R4P_” and suffixed by “_sound”, incorporating both video (10-bit Log) and audio tracks.
    • An audio WAV file, similarly prefixed,  generated as a “side effect”, may or may not be useful to you, can be deleted.


Cineform Free Codec for H264 Cameras (eg GoPro or DSLR)

Sunday, August 21st, 2011
    • David Newman of cineform just announced that cineform codec will be free for canon users.
    • Their 3d tool for the GoPro 3d system is getting re-released to be compatible with all cameras, from what I gather. It’s already free, though: — and for free, for any H.264 .mp4 footage, you can:
      • • Transcoding to GoPro CineForm codec
      • • Frame-rate adjust for slow motion
      • • Exposure
      • • Contrast
      • • Saturation
      • • Color Temperature
      • • Image flip rotation
      • • Frame Resize (Up-res/Down-res)
      • • Cropping and zoom
    • So if you take your 5d/7d/whatever footage and convert to .mp4 you can then convert to cineform using this free tool already.
    • Recently, it was announced that GoPro had acquired Cineform, and would be utilizing their tech in a 3D camera. We dropped by the Cineform booth at NAB 2011 to talk to David Newman about this change for Cineform, and how that affects their pro users.
    • (Video, interspersed with sponsor adverts: Interview with David Newman about GoPro/Cineform future plans and the free Cineform codec for GoPro that is also usable by Canon DSLR users)
    • The GoPro CineForm Studio is FREE to download.
    • Software is only available for Windows XP, Vista and 7 and Mac Snow Leopard 10.6.3 – 10.6.8. See complete list of System Requirements.
    • To use the 3D convergence features of this software, all imported files must be created with a GoPro camera.
    • The following features will work with any H.264 compressed .mp4 file created with most other cameras however GoPro does not guarantee compatibility:
      • Transcoding to GoPro CineForm codec
      • Frame-rate adjust for slow motion
      • Exposure
      • Contrast
      • Saturation
      • Color Temperature
      • Image flip rotation
      • Frame Resize (Up-res/Down-res)
      • Cropping and zoom
    • I successfully downloaded both Windows and Mac versions, in each case once I had entered my details.
