Scene Detecting a Composition
--scene-detect [F] [fields] [apply-effects] Scene detect supplied composition.
  • [F] - FLOAT number - optional - sensitivity (default 0.7)
  • [fields] - STRING - optional - use if field-based material
  • [apply-effects] - STRING - optional - scene-detect after effects are applied (default is source)

The --scene-detect option will scene-detect (add cuts) to the supplied composition (inside specified project).

Command :
C:\> nucoda -p daylight -c comp1 --scene-detect 0.8 fields apply-effects
...

INFO Opening project "daylight" from "D:\Nucoda\2014_2\projects\daylight".
INFO Opening composition "comp1".

INFO background scene detect (completed) : "comp1" - rendering frame 90258. 0 remaining (100)

Parameters

All parameters are optional.

  • F - the sensitivity of the detection as a floating point value e.g. 0.6. The higher the number, the greater the sensitivity.
    Default : 0.7
  • fields - if given, we process the footage as field-based media.
    Default : Frame based footage is assumed.
  • apply-effects - if given, we scene-detect after any effects are applied.
    Default : We scene-detect source (i.e. before effects).

If the sensitivity is too large for the footage, the danger of false positives increases i.e. incorrect cuts added.
