Stream: Short videos are blurry on mobile

So the original video is good, as in the one in the admin portal but when I stream from Cloudflare on a mobile device it is blurry.

I have uploaded the mobile screen grab and you can see the text is good but the video quality is very poor.

Have links for both but post said I can’ include links.

@zaid can I get some help on this please?

We are using this better_player for flutter on mobile. And short videos generally look like ■■■■ with is a big issue as we have a lot of them.
