               ColorSampler ColorSampler v1.0                

  

Tutorial/Overview video: https://vimeo.com/adrianpueyo/colorsampler

ColorSampler is a tool that calculates the average color of a target input (or the src image if there's no target input), weighted through the area input (or the whole frame if there's no area input). It can also calculate the maximum or minimum value over the area. Additionally, you can directly remove color flickering to an image, or apply it from a target.

You can think of ColorSampler as a live version of CurveTool with some additional features using the power of Blinkscript, where instead of being limited to a rectangle you can plug a roto to use for the sampling area... or a key... :)

Hi Adrian,

Very cool tool! :)

One thing I would like to mention is that the Export Flicker(src) isn't working like its supposed to. Even at the reference frame, the exported Grade has 'reverse' enabled and offset values at 1 which gives undesirable result. Maybe I am just doing something wrong.

Cheers mate

I get the same :/ but the node does the job.

[edit]

It seems to work but then it doesn't export any grades.

The button "create" results in error
Missing parentheses in call to 'print'. Did you mean print(l)? (, line 5).

For some reason, the gizmo that comes with Tony Lion's survival toolkit doesn't show errors right after loading, unlike the gizmo available for download here. So, starting with that version is recommended.

To get the CREATE button to work, you need to edit the gizmo file with a text editor. On line 22, add parentheses after the print command.
It currently reads: .... n.knob(\"linked \").value()\npr int l\nif...........
but it should be: ....... n.knob(\"linked \").value()\npr int (l)\nif ......

Thanks Adrian for sharing this amazing tool.
