Exciting enhancement! I've developed a custom node https://github.com/EnragedAntelope/ComfyUI-ConstrainResolution and included it in this workflow with Cosmos-specific constraints.
This will automatically make the Cosmos output as close as mathematically possible to your input image's Aspect Ratio, resulting in less loss and greater fidelity to your source.

What does this workflow do?
This will take your input image, crop/resize if needed to the ideal Cosmos render size, then automatically create an appropriate prompt for Cosmos to work its magic! The result will be a hopefully-amazing video that your family can cherish for generations.
This process is dependent on both Florence (for automatically describing the image) and an LLM (for creating a video prompt from the image description).
Further instructions and links are included in the workflow.
Extremely simple operation after initial setup (model load/LLM configuration):
1. Load an input image.
2. Queue prompt. Really, that's it. Every other setting should be good to go.
Have fun, and I look forward to seeing your creations!
Expectations setting: This model is HEAVY. Using the 7B model, with the included (optional) optimizations, I am running at about 15 minutes and 20GB VRAM usage on a 4090 to generate a 121 frame video at 1280x704.
