Still can't make sprite sheets :(

>"Still can't make sprite sheets :("

The key is making them one frame at a time, rather than asking for the whole sheet. Adherence frame-to-frame with a reference image is really good, so just prompt with the previous + direction. I finally got Nano Banana to make fairly decent fluid animations that way.

The "composite party photo", while impressive, shows that still the miniscule details are being lost, like the teeth structure of the guy in the middle or the fact that the guy on the left is holding the cup with three fingers. Wondering why they chose this edit for the showcase.

The dog is even more on the nose. The shadow shape is almost the same despite the dog getting quite a lot of volume around it's original body parts.

You can get semi-decent sprite work out of GenAI models, but you still have to put in some manual work (scale normalization, palette reduction, grid alignments, etc). It's definitely not "out-of-the-box" yet. https://mordenstar.com/other/hobbes-animation

Really nice share. I bet you could automate the manual work with today's models

The sheer waste that accompanies image and video genAI is actually terrifying. I challenge OpenAI to put a "your carbon footprint" field next to each generation. If you have nothing to hide, more information is surely better, right?

You can generate images on 5060ti, it'd take less than minute per image. Trivial environmental footprint.

I wish I could do it better. There seems to be a lot of variability. This episode of radiolab on the topic is fascinating: https://radiolab.org/podcast/aphantasia/transcript?utm_sourc...

Wow I haven’t thought about HI in years!

Omg, I love how the first examples just show how easy you can fake things. Fake being at a party with your friends. Didn't make your bed, no problem, just fake it. The sad part is my mother would love "remixing" my old child photos of me.

Yeah, the "3 lonely selfies -> fake 2006 party photo" is the most 2020s thing I've ever seen in my life.

I think @conradludgate was alluding to that we have so much of AI slop these days. But I see your point too. I too like to generate cute and funny images and share it with my friends and family. But this being done at scale can lead to overall degradation of the online experience.

plus the energy cost - https://www.technologyreview.com/2023/12/01/1084189/making-a... >Generating 1,000 images with a powerful AI model, such as Stable Diffusion XL, is responsible for roughly as much carbon dioxide as driving the equivalent of 4.1 miles in an average gasoline-powered car. In contrast, the least carbon-intensive text generation model they examined was responsible for as much CO2 as driving 0.0006 mi…

That study is from 2023 when the cost to produce 1000 images was 2.91 Wh per image. More recent numbers for Stable Diffusion's 2025 models that puts it at 1.3 Wh per image and that number continues to decrease.

For context that means a days worth of image generation emits about the same amount of carbon dioxide as a single transatlantic flight (New York to London). There are approximately 1500 transatlantic flights per day.

Okay, but firstly golf is probably the most useless sport ever and secondly there is more than one AI datacenter. Yes, some people have fun, but most of the "fun" nowadays is just endless mindless consumption.

How people derive fun is different from person to person.

The fun of some is the horror of others.

Every SDXL image uses something like 0.5 Watt-hour. That means that 2000 sdxl images uses about 30 cents of electricity. If we multiply that by 30x for video (a fair assumption for models like minimax H3, which take that much longer to make video), that means you get almost 700 5-second videos for a dollar of electricity, which is about a kilo of carbon dioxide. More or less depending on where your electricity comes from.
