 ### Whats New
 **14.0.0**
 - 🎉 video generation using [Stable Video Diffusion](https://github.com/Stability-AI/generative-models)
- - add `--videogen` to any image generation to create a short video from the generated image
- - or use `aimg videogen` to generate a video from an image
+  - add `--videogen` to any image generation to create a short video from the generated image
+  - or use `aimg videogen` to generate a video from an image
 - 🎉 imaginairy is now backed by the [refiners library](https://github.com/finegrain-ai/refiners)
   - This was a huge rewrite which is why some features are not yet supported.  On the plus side, refiners supports
 cutting edge features (SDXL, image prompts, etc) which will be added to imaginairy soon.
   - [self-attention guidance](https://github.com/SusungHong/Self-Attention-Guidance) which makes details of images more accurate
+- feature: added `--size` parameter for more intuitive sizing (e.g. 512, 256x256, 4k, uhd, FHD, VGA, etc)
 - feature: better logging output: color, error handling
 - feature: support for pytorch 2.0
 - deprecated: support for python 3.8, 3.9

  - add --size parameter that accepts strings (e.g. 256x256, 4k, uhd, 8k, etc)
  - detect if cuda torch missing and give better error message
  - add method to install correct torch version
- - add composition cutoff parameter
  - allow selection of output video format
  - chain multiple operations together imggen => videogen
  - make sure terminal output on windows doesn't suck
  - add karras schedule to refiners
+ - add method to show cache size
+ - add method to clear model cache
+ - add method to clear cached items not recently used (does diffusers have one?)
