OCTOPUS RAW Player – A lightweight and free cross-platform RAW video player

OCTOPUS RAW Player is a RAW video player for viewing RAW video footage from professional cameras. Currently, the player only supports CinemaDNG RAW .dng footage.

Although it’s a bit limited, it’s freeware and if you have some of the older cameras like a Blackmagic Cinema Camera 2.5K or a Sigms fp, it’s worth downloading.

Main characteristics

  • Modern minimal interface
  • Efficient real-time CinemaDNG playback for 8,12,14-bit bayer or monochrome, uncompressed or lossless compressed footage.
  • Professional RAW controls (white balance, exposure)
  • Advanced color science control (highlight recovery/dimming, SDR tone mapping)
  • Viewing timecode and metadata
  • Real-time 8K playback support


Currently, OCTOPUS RAW Player supports playback of CinemaDNG (.dng) sequences. To open a sequence, drag the folder containing .dng files or a single .dng image file into the player window. Alternatively, .dng sequences can be opened explicitly from the “File… Open CinemaDNG Sequence…” menu and selecting the folder containing the .dng files.

When a sequence is loaded, the floating playback interface provides controls for standard play/pause/seek as well as fast and fast playback speeds. The interface includes the timecode of the current frame and the duration of the clip. The timecode also indicates missing or skipped frames using a red or orange font respectively.


When working with CinemaDNG or any raw format, the image should be developed to look normal. Tools for working with RAW can expose control over the development process. These controls typically include white balance/tint and exposure, but can also offer more advanced and creative options. OCTOPUS RAW Player exposes several advanced commands while remaining simple to use. All RAW controls are located under the “Clip…” menu which is activated when a sequence is loaded.

Highlight recovery enabled (left). Highlight recovery disabled (right)
HIGHLIGHTS RECOVERY Enable this option to choose between simple highlight management and intelligent estimation/recreation of partially clipped highlight values.

HIGHLIGHTS ROLL-OFF refines the saturation curve applied to values ​​close to clipping. More roll-off creates a smoother transition from highlights to clipping.

REC. 709 TONE MAPPING The Rec. The 709 gamma curve limits images to a fairly narrow dynamic range of up to 6/7 stops. The application of tone mapping preserves greater dynamic range by compressing all exposure values ​​non-linearly in the Rec. 709 range.

REC. 709 COMPRESSION RANGE Similar to Rec. 709 tone mapping, gamut compression brings extreme colors out of the Rec. 709 inside by applying nonlinear compression.

OCTOPUS has tested RAW Player with the following cameras:

  • Sigma Fp
  • DJI Xenmuse X5, X5R, X7
  • Blackmagic 2.5K Cinema Camera
  • Blackmagic Pocket Cinema Camera (Original)
  • Blackmagic Micro Cinema Camera
  • Blackmagic Ursa Mini 4K
