Auto Cropping

In Crop tool, there is "Auto cropping" tab which does exactly what i want.
I just want to do that for every frame (cause result is different every frame).
Does anybody know expression for X, Y offset and X, Y size?

ASAP solution would be appreciated... Thank you

modify x and y with expression linked to the input size of your clip

right click on x and select expression
type the following
source.Input.Height / Width

replace source with the name of your node

modify x and y with expression linked to the input size of your clip

right click on x and select expression
type the following
source.Input.Height / Width

replace source with the name of your node

That won't crop the same as Auto Crop, which finds the first and last row and column with pixels that are not the same as the canvas color.

An easy way to do this is to use the AutoDomain tool, then read in the modified DataWindow table in the Crop tool:

Code: Select all

Inputs = {
   XOffset = Input {
     Expression = "Input.DataWindow[1]",
   },
   YOffset = Input {
     Expression = "Input.DataWindow[2]",
        },
   XSize = Input {
     Expression = "Input.DataWindow[3]-Input.DataWindow[1]",
   },
   YSize = Input {
          Expression = "Input.DataWindow[4]-Input.DataWindow[2]",
   },
     },

@chad
Is there a possibilty you make simple comp and paste code here?
Cause i'm not sure how to implement everything you wrote. Doing only what you described does... Well, nothing

thank you

I would like to know it too please

I wonder if it is possible with some script in the crop node to get the maximum values from the AutoDomain values. Then we could just play all the frames get those maximum numbers and set the values to the crop tool to get a fixed minimum crop needed for the clip.

Any ideas?

OK, now that I needed Auto Cropping I found out how to use the expressions.

Just copy and paste the code below in your Fusion flow. It'll add an "AutoDomain" node and a "Crop" node with the necessary expressions already in place.

Code: Select all

{
   Tools = ordered() {
      AutoDomain1 = AutoDomain {
         ViewInfo = OperatorInfo { Pos = { 715, 181.5 } },
      },
      Crop1 = Crop {
         Inputs = {
            XOffset = Input {
               Value = 896,
               Expression = "self.Input.DataWindow[1]",
            },
            YOffset = Input {
               Value = 829,
               Expression = "self.Input.DataWindow[2]",
            },
            XSize = Input {
               Value = 136,
               Expression = "self.Input.DataWindow[3]-self.Input.DataWindow[1]",
            },
            YSize = Input {
               Value = 140,
               Expression = "self.Input.DataWindow[4]-self.Input.DataWindow[2]",
            },
            Input = Input {
               SourceOp = "AutoDomain1",
               Source = "Output",
            },
         },
         ViewInfo = OperatorInfo { Pos = { 715, 214.5 } },
      }
   }
}

I hope this helps. Important note: There was a change in Fusion's expression syntax that requires to put "self." in front of the "Input.DataWindow". So the expression that was posted in 2015 no longer works.

Chad and Steffen, thank you so much, this very helpful!
