When it comes to video, it's the same thing. Compression does introduce image quality loss. At what level is the the quality loss acceptable, is what sets the standard.

That's absolutely not true from a technical perspective. ZIP files are a great example of lossless compression, as is PNG for images.
For video here is a list of lossless video codecs: https://en.wikipedia.org/wiki/List_o...ss_compression
It is completely technically possible to compress without loss, and this is done all the time.
