I am using this library to solve the problem that react-native-view-shot cannot capture video screen shot on IOS. And I encountered the qulaity problem, too. This is my solution and you can use patch-package to apply it.

I have used this create thumbnail to show on my social media app but the problem is that it degrade the image quality.
