%date:yyyy-MM-dd% works for save image, not for save video

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

Save Video node. filename_prefix
If I write:
05.video/%date:yyyy-MM-dd%/video_%width%x%height%
video is saved in the subfolders and with the following name:
05.video/2025-10-10/video_1024x1024_00001

### Actual Behavior

Save Video node. filename_prefix
If I write:
05.video/%date:yyyy-MM-dd%/video_%width%x%height%
I get an error once the video is generated.

### Steps to Reproduce

write %date:yyyy-MM-dd% in the save video node. It won't save the video.

### Other

Save Image node works fine. I can write for example:
01.txt2img/%date:yyyy-MM-dd%/txt2img_%width%x%height%
which will save images in
01.txt2img/2025-10-10/txt2img_1024x1024_00001

%width%x%height% works for save video.
%date:yyyy-MM-dd% doesn't work.

Could you please update this node to be sure that "complex" filenames work as well in the save video node as in the save image node?
Thanks.
