In fact, 'not that hard' would be:
  git clone https://aur.archlinux.org/cinelerrag-gg.git
  cd cinelerra-gg
  makepkg -LCcf

With build you mean source tarball, right?

Where does the PKGBUILD come from? Where is it maintained? After all, it
is not the same as the one in the source tarball (see my note about
confusing sources and structures).
Why is the --disable-static-build option to configure not documented,
the various --disable-option possibilities are though?

You will want to use devtools for that to achieve reproducibility.
Also, there's no reason to use sudo here. Additionally, makepkg has a
builtin log feature ( -L ), so there is no need for piping to tee
manually.

That is not what pkgrel [1] is for (hence my quote on versioning)!
What you want is a consistent versioning, reflected in pkgver [2].

For me this ends right at configure in:

  checking whether X_HAVE_UTF8_STRING is declared... no
  configure: error: Cinelerra requires utf8 support in X Windows.

which is strange, as I have not run into this before!

There are `--without-firewire --without-dv --without-dvb
--without-video4linux2`, but the package dependencies are still pulled
in in depends (also, that array should be named lower-case, not all
upper case letters).

To get clarification about the dependencies, as this really doesn't jump
at me: It seems to be okay to disable libzmpeg and commercial, but what
is the latter actually pulling in/providing?
I assume, that people would want something like lv2 integration. What is
the rationale behind it being disabled?

Another thing I found out is, that for ladspa integration, there's
always the local version used, even if I provide `--disable-ladspa`, it
is set to "forced".

What one really should to do is to run namcap [1] on that package,
instead of installing it!
This would also help in decimating the huge amount of unneeded
dependencies, this package pulls in (some of which should at best be
optdepends, but many are already provided by pulling in one of the
others)!

Best,
David
