Haha, I didn't even think about video.

I guess video's more complex because you have to factor in how many dots are used (e.g. 720x480), while for audio, we all pretty much agree on 44100 dots per second (and for some reason, lossy codecs aren't used for the few high-resolution things like 24bit/96khz). Are there standard recommended settings for video encoders, same as audio encoders, that'll generally give "transparency"?
