Why are the Velaryon subtitles so small on HotD compared to GoT

[Kellymarie86]

Is it just me or is anyone else struggling to read the subtitles when they are speaking Velaryon, I rewatched season 1 before season 2 started and I could read them fine, I'm also rewatching GoT and no problem but if I watch HotD season 2 on my sky glass the subtitles are that small I can bearly see them yet when I watch on my smaller tv in bed through sky stream puck the subtitles are bigger and readable

I think that's a design choice to show it's a translation of an in-show language.

There's also a known problem where a viewer is using 'real' (hard of hearing) subtitles and in-show translation subtitles overlay these, making both illegible, so the in-show text is rendered at a size and location to avoid this.

Incidentally the language is High Valyrian.

Velaryon is the noble house of Driftmark.
