I upload short videos to my Facebook Page, and they look sharp on my phone before posting. Once they’re live, though, the image can look softer or more compressed, especially when there’s text on screen. The original file looks fine on other platforms.
Is this usually caused by Facebook video upload quality settings, the export format, or the way the app processes a video after it’s posted? I’d also like to know whether the result looks different to viewers on slower connections or smaller screens.
