@Ben Bredl we actually do the style sheets now mostly with GPT.2 at medium or high res. It looks ugly, but when it goes through Seedance it loses the ugliness. Then you combine this with the 1k base still and works very smooth. Now, if you are making a wide shot with people, sometimes you need to test if the 1k image is working better or not than the 2k. It's not a 100 but maybe 85% science. This tip you are saying looks cool, is doing similar to what we say. We properly tag the images references on the prompt and it works good already though. About upscalers: For Image we only use them when need to deliver high res print quality. Then the process varies depending what we have. Usually mix Magnific at different settings, Topaz AI Image (sometimes at different settings too), Photoshop the best parts of every upscaler and if needed Topaz Gigapixel :) Used to work very good using Seedream 4 4K as upscaler, but it always changes a little bit the image and can be annoying. It's skin texture though is probably the best. For video definitely only to be used from Full HD to 4K, and never to improve detail, just resolution. Otherwise they look very ugly.
