Highly compressed videos?

[Sirvalion]

The scenes that are predetermined and are videos and not the engine of the game, I see pixelated, probably because they are too compressed or the resolution of them. For example, the intro of the game looks much worse than the intro that can be seen for example from YouTube.
Is there any way for this to not happen ?, and if not, I hope that in some update they put the videos in better quality, or at least give the option to download them in better quality for those who want them, since I think the quality is very low.
