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 sequences can be opened explicitly under the "File…Open CinemaDNG Sequence…" 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 also indicates missing or skipped frames by using a red or orange typeface respectively.
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. All RAW controls are located under the "Clip..." menu which is enabled when a sequence is loaded.
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 ROLL-OFF Roll-off allows for fine tuning the saturation curve applied to near clipping values. More roll-off 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.
