    MP3 is very high quality lossy compression because of the psychoacoustic modelling to know what our brains don’t process when hearing, and dropping only that. This includes frequencies outside of our hearing range and effects like masking where loud noises of a certain frequency mask adjacent frequencies. The compression only loses the parts no one hears.

    Your post, while not specific, was talking about video. Lossy video compression loses quality that we can perceive. Upscaling can help with some of it, but you can only interpolate so much.
