How to encode a movie with mostly still images?

First ... I'm a newbie to these things ... if me question should sound strange ;-)

In youtube you can find many "videos" that actually aren't videos at all.
In the sense that it is (for example) the audio from an old LP record,
and the video consists of nothing else but a still image of the cover art,
maybe with some blending at both ends and blending of the individual tracks.
Although there are new codecs used, the video information makes about 2/3.
For example
https://youtu.be/NJnRHc7tp10
56% (37 MB) only for 7s of blending and 10 track title frames (= less than 1 MB).
My question:
Why do the video codecs do so bad on that?
Is there a more clever way to combine audio and video in that cases?
Optimal would be to set times/ frames from where to show a still image
or a few frames...
Strange idea?
