Rendered text blurry only if it's blue

[Matyáš33500029ned3]

I have a weird issue. When I go and render my video with a text layer with a blue color, it appears blurry in the final video. But when I change the color to green, it looks completely sharp. I don't change the render settings, anything. How come this happens?

There's nothing wroing with your images. If at all, the chroma undersampling in MPEG compression formats can cause issues with blue colors since there is less information compared to the red and green channels, but that's nothing you can change.
