Qwen edit can take an image as a sample, and work with that. “The character in a victorious pose” would get whatever character you have, and reproduce it in a victorious pose. Couple of examples:

And a little janky because it IS generative AI after all…

Edit: and a bonus screenshot showing how little effort I had to put into this lol

    As far as I know, one way to do it is to use an image2image model / image editing model. You'd need to generate one reference image of your character. And then feed the reference image into it and tell it to draw that character in a different scenario. I haven't done it in a while, not sure what people use these days to do it locally.

    My limited experience is that stable characters across a number of images are a weakness today, and I wouldn't be confident that genAI is a great way to go about it. If you want to try it, here's what I'd go with:

    • If you can get images with consistent outlines via some other route, you can try using ControlNet to do the rest of the image.

    • If you just need slight variations on a particular image, you can use inpainting to regenerate the relevant portions (e.g. an image with a series of different expressions).

    • If you want to work from a prompt, try picking a real-life person or character as a starting point, that may help, as models have been trained on them. Best is if you can get them at once point in time (e.g. "actor in popularmovie"). If you have a character description that you're slapping into each prompt, only describe elements that are actually visible in a given image.

    I've found that a consistent theme is something that is much more achievable, in that you can add "by " to your prompt terms for any artist that the model has been trained on a number of images from. If you're using a model that supports prompt term weighting (e.g. Stable Diffusion), you can increase the weight here to increase the strength of the effect. Flux doesn't support prompt term weighting (though it's really aimed at photographic images anyway). It's possible to blend multiple artists or genres as prompt terms.

    Honestly, this refinement seems like it's gaming the metric a bit. I have no doubt there's innovation here, don't get me wrong, but the first two examples are not just retaining the character, they seem like overfitting.

    The model in many of the images reproduces the exact same armor angle, shield angle, head/helmet angle, etc, without any modification - i.e., it isn't learning how to reproduce a persistent character in multiple angles, scenes, etc, just the exact illustration fed into it, while changing the setting and positioning.

    I think that there's maybe a need for something like this, but if it's not just going to be a one-off research project


    which maybe this is, which is okay


    I'd very visibly version the testset and its results from the get-go. You're going to want to add more tests to it over time, and it'll affect change test results, and you're going to want to be able to reproduce results.

  • That's pretty impressive that they show it from the 2nd grader blob sketches to the finished animation.

    This really does look like a signal to where the future workflows will be, because careful key-framing addresses a lot of artificiality inherent in AI video.

    Yes but not everyone has something that can run a local model. We also specify exact versions of the local models we run so people can replicate locally if they want. Still don't see why your approach dismisses the whole extension.
