Colors not matching after exporting

[David_Rodriguez]

I want to share something I’ve noticed happening with my Speed ​​Paint projects. The color of the drawing in Speed ​​Paint changes slightly from the original.
It’s not a complaint; it’s not until you put them side by side that you really realize the differences. Oh, does this happen to you too? The one on the left is the original drawing, and the one on the right is Seed Paint.

Spanish:

Les quiero compartir esto que he notado que me pasa en mis speedpaint. El color del dibujo en el speed paint cambia un poco con respecto al dibujo original.
no es una queja hasta que no los pones lado a lado es que te dascuentas realmente de la diferensias.
ah ustedesde tambien les pasa? el de la izquierda es el dibujo original y el de la derecha es seedpaint

The one on the left is the original drawing, and the one on the right is Seed Paint.

Either both pictures are speed paints or non of them are, can’t be both, unless you painted them separately.

Have you checked that both use the same color model and profile? Because if not, that’s usually the culprit when colors mismatch.

To be honest, I don’t know if Krita can configure the color model in Speed ​​Paint. I only export it when I’m finished.

But in drawing, I use the RGB/Alpha model.

I get the feeling you are actually talking about a time lapse, do you? Like when you use the recorder docker? A speed painting is just a painting you painted as quickly as you can.

The color model of the rendered recording might be depended on the codec that is used but I don’t really know.

@David_Rodriguez

RGB/Alpha model.

what exact profile?

When I export as MPEG-4 the colors are darker than they were before

As far as I know, It’s not a color workflow issue on your side (thank you for sharing all your screenshots). Video color spaces are really different, so it’s not a particular surprise if you have color shifted in the translation. MP4/h264 is − as far as I know − Y’CbCr color space based under the hood. Check this picture to see the difference with an RGB. For a summary: it’s a grayscale image recolored with two channels. So a rather heavy conversion. Krita probably relies on FFmpeg settings …

im now using sRGB-elle-V2-srgbtrc.icc, the colors aare the same Edit: I tried exporting the same color on Pencil2D and it exported the same, as well as other devices

[David_Rodriguez]

Hi, sorry for the delay. This is the type of color profile I use; I don’t usually change it, even when exporting the video.

The most I usually change is the RGB/Alpha model to grayscale.

Looks good to me, the default color space is pretty good for most stuff. My guess it is really because of the codec, as Deevad mentioned in the topic I linked, video color spaces act a bit different so that could be the case. I don’t know if there is something that can be done about it, unfortunately. Perhaps someone else knows. You could try different video formats to see if it makes it better or worse.
