Open Cine | apertus° - open source cinema

Open Cine

This software is under active development - it is not yet ready for end users. We are looking for software developers! Help us to push it further.


There are several free and open raw-image processing tools for still images like: ufraw, darktable, RawTherapee, digiKam and many more. While some of them offer batch processing capabilities none of these tools were designed for moving pictures. Processing DNG sequences is cumbersome and time consuming, CinemaDNG MXF files are not yet supported at all.

This is where Open Cine should come in. It will be a raw processing tool designed from the ground up for moving images instead of still images.

Feature Overview

  • Import Footage from Camera over network (FTP Transfer to backup location)
  • Import Footage from local drive
  • Preview Footage in real-time (GPU based raw debayering at full/reduced resolution [Reduced resolution equates to better playback performance])
  • View(all) / Edit(some) Metadata
  • Set IN/OUT points in footage
  • Apply color relevant RAW transformations (Whitebalance, Exposure, Curves, etc.)
  • Save/Load color transformation presets to/from File.
  • Adjustments are preserved in a XMP file that stays with the original unaltered footage.
  • Compare Color transformations (Presets A,B,C; split screen, etc.)
  • Live Histogram/Vectorscope
  • Batch Export RAW footage between IN/OUT to non destructive RAW conforming format
    (DNG, DPX, etc.)
  • Batch Export RAW footage between IN/OUT to destructive digital intermediate format
    (Quicktime Prores444, AVI DNxHD, Image Sequence, etc.)
  • Batch Export RAW footage between IN/OUT to destructive proxy format
    (Quicktime Prores422 (proxy), Quicktime/AVI MJPEG, etc.)

Typical Usages

Reviewing and Sorting Footage
  • Import DNG sequence that was shot with a raw camera (Apertus or other) into Open Cine
  • View footage in real-time
  • mark unneeded clips, rate good clips, write comments for each clip
  • later a filter can be used to hide all the bad/unneeded clips. Director could now review only the good ones and continue working with them.

Prepare Footage for Editing
  • Import DNG sequence that was shot with a raw camera (Apertus or other) into Open Cine
  • Sort through footage and select best clips (rating, marking), shorten to relevant parts in the clips by setting IN/OUT points
  • Apply color grading nodes to the raw footage (White-balance, Exposure correction, Tonal Curves, etc.)
  • Export Intermediate Clips in FullHD as Avid DNxHD or Apple ProRes for editing in another software

Prepare Footage for Finishing
  • An EDL/XML file of a complete edit contains the list of clips we need for finishing, import EDL/XML and link the clips to the raw footage (big win if we find a way to do this automatically)
  • Apply color grading nodes to the raw footage (White-balance, Exposure correction, Tonal Curves, etc.)
  • export required clips as *.DPX or *.EXR image sequence (with full bitdepth) for finishing suite

Moving Offices For the last two years the AXIOM headquarters has cohabited from the modest Amescon facilities in the 15th District of Vienna, Austria. This is where most of the electronics manufacturing for the AXIOM Betas has taken place. This spring we began the process of moving to a new, bigger and better shared office called Factory Hub Vienna - this was quite a challenge as the pick and place machine was built and assembled inside the old office and so it wasn’t clear whether or not the... » Read more
We are very proud to announce that apertus° has been accepted as a new mentoring organization for this year’s Google Summer of Code (GSoC) . As only a small number of new organizations are allowed to join each year and the majority already in the program have been participating for many years, this is especially exciting. For anyone not familiar, GSoC is a program where students are paid to contribute to selected open source projects between June and August. Project Overview apertus° GSoC... » Read more
