Baking sRGB display view?

Discussions - Using ACES
1

Howdy all, wanted to check in to make sure I’m doing this right. I’m looking to bake sRGB Display view into an image file. I found a convo here on the topic and this is what I’ve come up with. Images produced this way look right, but looks can be deceiving. Just want to make sure this approach isn’t messing up any math that might cause problems later. This is basically just the official “CG” config with a few small changes. The baking transform is at the bottom. Thank you!

displays:
ACES:
- ! {name: sRGB, view_transform: ACES 1.0 - SDR Video, display_colorspace: sRGB - Display}

view_transforms:

  • !

I think your code is getting cut off when you post it here. You need to use the “pre format text “ option. Here’s what that last part should be, using a Display View Transform


  - !<ColorSpace>
    name: ACES 1.0 SDR-video (sRGB - Display)
    family: Baked View Output
    isdata: false
    encoding: sdr-video
    from_reference: !<GroupTransform>
      children:
        - !<DisplayViewTransform> {src: ACES2065-1, display: "sRGB - Display", view: "ACES 1.0 - SDR-video"}
        - !<RangeTransform> {min_in_value: 0., min_out_value: 0., max_in_value: 1., max_out_value: 1.}

Oops, it did cut out a bunch of stuff. Thanks for the code, that matches what I had so I should be all set!
