Optional post-processing: RTX Video Super Resolution

https://pypi.org/project/nvidia-vfx/

The ``rtx-postprocess`` extra installs NVIDIA's proprietary Python bindings
for RTX Video Super Resolution and deblur. It is optional, dynamically loaded
only when an RTX preset is selected, and is not redistributed as source in
this repository.

Post-processing presets
-----------------------

Post-processing presets run on decoded RGB frames from a video runner. Select
one with ``--postprocess.preset``:

.. code-block:: bash

uv run flashdreams-run wan21-t2v-1.3b-480p \
--postprocess.preset rtx-super-resolution

The ``rtx-super-resolution`` preset wraps NVIDIA VFX Python bindings for RTX
Video Super Resolution. Install the optional dependency with
``uv pip install 'flashdreams[rtx-postprocess]'`` and run on a supported RTX GPU
before selecting this preset.
