Four year later and AE still does not support a very common typically STmap workflow for professionals.

Here is a very basic approached this kind person “Liz” helped try to sort out. God bless you. Great job, For any AE compositors that has stumbled on this thread trying to find answers. Although this is still plagued with issues I wanted to share a one size fits all approach you can try. That is until years from now they bring back proper support for this workflow.

This did work for me. Thank you for the suggestion. Curious if other folks do something different. Do you ever monitor skin tones this way?

[Antony Dupsta]

Thanks so much for your reply and help.

I need a hand with monitoring the final output of the isolated skin tones when I highlight a small area to check skin tones. When I isolate that area with a small mask and then click on the highlight, the vectorscope is now seeing the log skin tone and not helping me determine what adjustments to make to balance them.

I simply want to learn to isolate, or mask a part of the skin and have my vectorscope tell me where just those values falls in rec709 color space. Not the entire scene.

For example, import a LOG clip into your project. My color science is a DWG working color space. My color management is node based.

I have an input Color transform from the camera system Log to DWG. All my color decisions are completed in this DWG working space then the last node is a CST rec709.

So if you have a skin tone serial node upstream from your rec 709 CST. You place a small mask over the cheeks and highlight this area to isolate the skin tone from the rest of the shot, the vector scope shows me a small almost invisible dot in the center of the vector scope as it is reading a flat unnormalized Log clip. As I have the highlight function on so the vectorscope is only seeing the skin. If I turn off the highlight function then the vectorscope sees the entire scene.

Is there a way for me to mask and isolate my skin tones so I can see just skin tones, on my vectorscope, not the entire scene? But see them in rec709 not log.

Or can you help give me an alternative solution, I do not see anyone else asking about this so I am clearly missing something, feel free to point out the obvious if this is right under my nose here.

Wanted to check in with the world, see if AE has figured out how to resolve reading frame numbers with EXRs.

Thousands of images sequence later, non of these seqs starting on frame 0. Yet every comp by default is set to frame 0 rather than reading the meda data. However, DPX works, jpg, png, you can bring them in and the comp is set to those frame frames. 780-980. However, still in 2023 AE by default sets EXR seq to frame 0 no matter what the frame range starts with.

import EXR seq 1001-1200

drag into comp

comp auto populates duration 0-199

Gotta be a fix to this a decade later.

Dan, you are a wizard.

Can I say how much I appreciate your time helping me and I know others who have inquired about this, helping them too as they read this thread.

Can I pay you or buy something from you?

A Monetary Expression for AE expressions!

Thank you so much. You are brilliant.

Have a great week!

[Antony Dupsta]

Dan, this worked perfect,

You are so amazing, thanks you so much.

I feel terrible to ask you to help modify this wonderful expression to be even more specific. If Possible?

In your expression you identify marker 01 and marker 02.

This is perfect I can make this work. But I was going to get greedy here?

Instead of d + m.key (2) .time Is there anyway to instead of saying (2)

You are able to code it to say “last marker” so if we have markers for the handle in edit in, edit out handle out, I was curious if there are 3 markers or 2 or 4 or 5, I can simply know that the last marker will alway be the end of the duration regardless of the other markers in-between?

Man I feel like I should just be quite as I wear out my welcome here, but if you are able to help identify the “last marker” as the end of the duration, we are golden. If not, I can make sure there is only ever two for sake of uniformity. Thanks again.

[Antony Dupsta]

Hi Dan, thanks for your help.

So this second one is soo close, it is able to display the frame range marker 01 – marker 02 as a window burn as hopped. Yea.

However, it overrides what the composition’s start frame is. For example if Comp B start frame is 900 -1200. The frame range that is displayed with this expression is 0-300. It sees the markers display is based on AE’s default 0 frame start rather than what comp B’s frame is set to.

so close.

To take a step back, I am needing an automated way to display a window burn that displays the range of the markers, or maybe a guide layer. So you can read the frame range of the seq as an overlay, not the current frame, the frame range. For example 900-1200. This will hopefully be automated with an expression so we are not typing in the frame range for each seq. We are not able to use the frame range of the comp though, as that stays as a large fixed duration and the work area is set inside the fixed comp length to create the sub duration. 900-1200

If you have any other insight to help that would be much appreciated.

Thanks so much.

[Antony Dupsta]

What if I set a marker for in and a marker for out. Could and expression determine the frame range between two points?

Or a solid that is a duration, I can drag the solid or Null and the frame range will update to how long this guide layer is and update the window burn. This may be easier than clicking into the text later and manually changing it.

[Antony Dupsta]

That worked perfect. Thanks for helping me with this expression. Much appreciated.
