Backwards compatibility is fine and all, but sometimes we can do better
by observing that the world has moved on. In particular:
-* It's 2015, so people want to edit HD video.
-* It's 2015, so everybody has a GPU.
-* It's 2015, so everybody has a working C++ compiler.

limited support for working with interlaced video; it has a deinterlacer,
but cannot currently process video in interlaced form.
Exactly what speeds you can expect is of course highly dependent on
your GPU and the exact filter chain you are running. As a rule of thumb,
you can run a reasonable filter chain (a lift/gamma/gain operation,
