Blender – Bake NLA animation

Software:
Blender 2.79

When you wish to bake your NLA animation mix into one Action,
The Bake option in the Animation tab will not work.
The way to do this is to:

  1. Select the object in Object Mode.
  2. Press Space and type ‘bake
  3. Choose Nla: Bake Action
  4. In the Bake dialog, select Pose, deselect Only Selected, and press OK.
  5. After the process, the Armature will have a new action that is the baked animation.

Premiere – ‘Composite in Linear Color’ breaks dissolve transitions?..

Software:
Premiere Pro CC 2018

I was baffled,
Not understanding why my dissolve transitions in a new Premiere project are not linear, and too lift too fast,
I validated this in the Lumetri Scopes window.
In an older project, at 50 percent transition duration, white color is at 50 percent intensity like you’d expect from a linear transition.
But in my new project, at 50 percent transition duration, white color is at about 75 + percent intensity as if it’s gamma corrected.

Solution:
After some web research in discussion groups, I found that the option that doe’s that is:
Sequence Settings > Composite in Linear Color
And unchecking it solves the problem.

It’s still weird to me that Composite in Linear Color breaks the linearity of the dissolve transition,
But at least there is a solution.

Clamp Colors in Photoshop 32 bit float Color Depth

Software:
Photoshop CC 2018

Photoshop CC 32 bit float linear workflow is developing nicely but it still lack some needed basic components, and one of them is a Clamp Color Adjustment, equivalent to a node you will find in any 32 bit float HDR capable compositing software.

Clamping the colors means limiting the britest values to set values, usually 1.0 – white and 0.0 – black, so that no pixels will have higher than white or lower than black (negative) values that can create unwanted results in further operations.

* Brighter than white (super-whites) and negative colors are a feature, and part of linear 32 bit float color processing.

* If there is such an option that I didn’t find please let me know..

In order to clamp the layers colors we convert it to a Smart Object, and convert its color depth to 16Bit internally, so the individual layer gets clamped but the main document remains 32Bit float unclamped (HDR).

To clamp the colors of a layer:

  1. Convert the layer or layers to a Smart Object.
  2. Enter the Smart Object for editing.
  3. From the Image > Mode  menu, choose 16Bits/Channel,
    And in the Conversion dialog that opens choose ‘Don’t Merge’, or choose Merge and then in the HDR Toning dialog choose Exposure And Gamma mode to keep the image unchanged.
    The conversion to 16Bit color depth without Merging or Merging using default Exposure and Gamma mode will clamp the colors.
  4. Save the Smart Object.
  5. Return to the main document, the layers colors are now clamped.
