Two faces , difficult to know where the skins are on the waveform or the rgb
parade
SUMMARY
Hi Kdenlive team,
first of all, thank you for the continuous work on Kdenlive.
It has become a very solid editor, and the recent improvements in color
handling and scopes are greatly appreciated.
I would like to propose a feature related to color analysis and scopes that
would significantly improve precision when doing basic color correction,
especially for skin tones.
### Current situation
At the moment, scopes (waveform, RGB parade, vectorscope) analyze the entire
frame globally.
When working with real footage, it is often difficult to understand where
specific elements (for example, skin tones) fall on the waveform or parade,
because they are mixed with background, highlights, and other objects.
A common workaround is to:
- duplicate the clip,
- apply a Transform or Crop effect,
- zoom into the face area,
- read the scopes,
- then remove the effect.
While this works, it is quite cumbersome and breaks the grading flow.
### Feature request
It would be extremely useful to have one of the following (or a combination):
1. A **Pixel Inspector / Color Picker** in the Program Monitor
- Clicking on the image would show RGB / luma values of the selected pixel
or small area.
2. **Region-based scopes**
- Ability to limit scope analysis to a selected region (for example via a
simple rectangle or mask).
- This would allow precise reading of skin tones, highlights, or shadows
without affecting the clip.
3. Optional display modes for scopes
- IRE scale (0–100) or higher bit-depth scale, even if internally
normalized.
### Use case
This would greatly help for:
- skin tone exposure evaluation,
- broadcast-safe adjustments,
- educational use (teaching color correction),
- professional workflows where precision matters but full grading tools (like
Resolve) are not required.
I understand this may involve deeper changes in how scopes access frame data,
so this is meant as a long-term feature request rather than an immediate
expectation.
Additionally, I use Kdenlive both professionally and in an audiovisual
education context (image and sound school), so this kind of feature would also
be very valuable for teaching color correction concepts to students, helping
them understand exposure and skin tones more clearly.
Thank you for considering it, and thank you again for your work on Kdenlive.
