I've read that Turing was trying hard to get the intuitive idea
of "effective procedure" right, by whatever means.

I also seem to remember reading that he tried to justify
how instructions for manipulating symbols could be
translated (like what a compiler program does for source code)
into a Turing machine table with conventions for entering
the data and reading the output.

So you could have Turing machines which take as input
a video/audio signal and give as output a file/data stream
compatible with one of the standards in
H.264/AVC/MPEG-4 Part 10 (Advanced Video Coding),
for Youtube etc. But it would take forever.
