That's an issue with tar. Tar is limited in it's design, probably
because of the physical medium it was designed for [0]. There are
other formats that can handle this type of problem, and problems
similar to this random access issue in a more efficient manner. I
don't think any animation would amount to this being an appreciable
problem though.
Animations are not so large that I would think this is a problem, and
to add a metadata file for the one use case of knowing the animation
duration doesn't seem suckless.
