My comment is quite correct and on-point. If the artifacts _can_ be shown in 
a single frame or a short clip there's no reason to _not_ to provide those, 
and that doesn't preclude _also_ making larger files available (inclusive 
OR, not exclusive OR).

Having smaller samples available actually widens the group of people willing 
look at them; not everyone has gigabit Ethernet to their home or office, 
some of us have considerably slower 'net connections and we're not as likely 
to download a large file but will look at the frames and shorter clips. 
(Please do me the courtesy of not disagreeing with that as it directly 
states my position and that of some fellow engineers.)

We do, well, I do, although large samples are not always necessary, or even 
desirable (if 5MB shows the problem, why include 200MB?). Log files need the 
same handling- make the full log available but also excerpt the relevant 
parts so people don't need to wade through thousands of lines looking for 
the two that are useful. If some folks don't want to look at the excepts, 
they don't have to, but some of us will.
