Raw CinemaDNG Compressor Slimraw Gets Firmware Update 1.8.2

Shooting raw today may not be as complex as in years past, but still requires a heavy investment in post-processing and storage. Shooting raw gets you maximum creative flexibility in post and the best possible image, but most times, it makes a lot of sense to somehow save some space, but still retain the benefits of shooting raw. This is where cool pieces of software like Slimraw come in really handy.

You may remember a while back, we posted about slimRaw – a really handy piece of raw compression software for those shooting with just about any form of raw whether it being a Blackmagic Design camera or a Magic Lantern variant for the Canon 5D Mark III for example.  Sony cameras such as the Sony FS5 when combined with the Odyssey7Q+ are also compatible, among many others (see a full list of supported cameras below).

For those, who may have missed this post slimRAW is a fast CinemaDNG compressor that converts uncompressed CinemaDNG raw video to lossless compressed CinemaDNG. The best part is that this conversion doesn’t affect the image quality of the initial files. Furthermore, the lossless compressed raw video output of slimRAW is exactly the same after decompression as the original uncompressed video.

slimRAW v1.8.2 Details:
  • Improved handling of corrupted compressed input.
  • OS X version: slimRAW now notifies the OS when processing is in progress to prevent the system from sleeping due to lack of user activity.

In previous firmware updates, Slimraw added the ability to downscale CinemaDNG raw to half its original resolution, allowing users to get a 2K CinemaDNG from 4K CinemaDNG, 2.3K from 4.6K (very handy for those who want to save hard disc space and shoot with the Blackmagic URSA Mini), etc.

For those willing to save even more space, but sacrifice a little bit of quality there is a 7:1 lossy CinemaDNG compression mode and now support for Magic Lantern in-camera lossless DNG stills.

Together with the previously available raw compression functionality, this allows huge data size reductions (up to 20:1 or more) and facilitates a Raw proxy workflow for high resolution CinemaDNG production.
