CUDA out of memory, feature request

[nitinmukesh]

This looks really wonderful. Many thanks for sharing with the community. I gave up looking at the System requirement and Graphics card requirement but thought no harm in trying.

So I tested on Windows 11 + RTX 4060 8 GB VRAM + 16 GB RAM and it worked. The changes I did was to keep the frames inside motion to 20 frames and deleted remaining from all folders within motion. [EDIT] Tried with 40 motion frames and it worked without complaining. :)

1. requesting to add a feature of batch processing and the number of frames can be specified in configs/inference.yaml
2. Correct the system requirements to also include Windows. along with Ubuntu20.04

Here is the output https://github.com/fudan-generative-vision/champ/assets/2102186/b3fc3b93-a5cc-4ef7-94d3-22cd4e5ed9f3
