Research direction

Use the save video node with the reported filename pattern as the reproduction case, then compare its handling with the save image node. Done means the date pattern is converted instead of written literally, with the behavior verified on the reported example.

Written by the indexing model from the issue text.

Description

When using the save video node with an output filename such as video/%date:yy-MM-dd_hh-mm-ss%, the file gets named literally instead of the formatting information getting converted like with the save image node.

I am running ComfyUI from Debian 13 using pyenv Python 3.12.3 and venv in case that is a relevant factor.
