OCTOPUS RAW Player is a RAW colour science processing video player for reviewing RAW video footage from professional cameras. Currently the player supports CinemaDNG RAW .dng sequences.

Features

  • Modern minimal interface
  • Efficient real-time CinemaDNG playback for 8,12,14-bit bayer or monochrome, uncompressed or lossless compressed .dng sequences.
  • Professional RAW controls (White balance, exposure)
  • Advanced colour science control (Highlight recovery/roll-off, SDR Tone-Mapping)
  • Timecode and metadata display
  • Support for real-time 8K playback


Tested Cameras

  • Sigma Fp
  • DJI Xenmuse X5,X5R,X7
  • Blackmagic Cinema Camera 2.5K
  • Blackmagic Pocket Cinema Camera (Original)
  • Blackmagic Micro Cinema Camera
  • Blackmagic Ursa Mini 4K
  • OCTOPUSCAMERA 8K/4K/MONO

User Guide

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

When a sequence is loaded, the floating playback interface provides controls for standard play/pause/seek and additionally fast and fast-rewind playback speeds. The interface includes the current frame timecode and the clip duration. The timecode can also indicate missing frames (in red) and skipped frames (in orange).

RAW Controls

When working with CinemaDNG or any raw format, the image needs developing to look normal. Tools for working with RAW can expose control over the developing process. These controls typically include white balance/tint and exposure but can also feature more advanced and creative options. OCTOPUS RAW Player exposes several advanced controls while remaining straight forward to use.

Advanced Colour Science Controls


HIGHLIGHT RECOVERY Toggle this option to choose between simple highlight handling and intelligent estimation/recreation of partially clipped highlight values.

HIGHLIGHT ROLLOFF Rolloff allows for fine tuning the saturation curve applied to near clipping values. More rolloff creates a smoother transition from highlights to clipping.

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

REC.709 GAMUT COMPRESSION Similar to Rec.709 tone mapping, gamut compression brings extreme colours outside of the Rec.709 gamut inside by applying non-linear compression.

Roadmap

2022

  • Wider CinemaDNG / DNG support
  • Additional RAW formats
  • Audio playback

2023

  • Performance improvements
  • Proof quality debayer
  • Export to Apple ProRes / GoPro® CineForm
