An example I just found worked very well with fine-tuning: I wanted to extract any frame that contained a full-screen presentation slide from a various videos I've archived, only when it's full-screen, and also not capture videos, and some other constraints.

Naturally I reached for CLIP+ViT which got me a ~60% success rate out of the box. Then based on that, I created a tiny training script that read `dataset/{slide,no_slide}` and trained a new head based on that. After adding ~100 samples of each, the success rate landed at 95% which was good enough to call it done, and circle back to iterate once I have more data.

I ended up with a 2.2K large "head_weights.safetensors" that increased the accuracy by ~35% which felt really nice.
