Hey y'all, been traveling so pretty busy!

I've mostly figured out that the base H3 model with good keyframes can more or less do very good character swaps. No Lora needed!

I'm still looking into various ways to make this use only open source models. Right now it uses GPT Imagegen 2.5 to create the frames which is less ideal.

I also still need to test the new Viggle model and H3 ripple edit lora 😅

Introducing OpenCast Studio!

A free and open source character generation tool with both character swap and motion transfer built in!

A custom Krea 2 lora lets you generate funny characters, then Flux 3 generates an anchor, finally the new Pika H3 Flex model performs the swap or motion transfer.

It's composed of ComfyUI workflows under the hood and only uses open source models.

This is my submission for the #OpenSourceHiggsfield competition!

Hi friends I'm back, now in Tokyo!

Testing out the new Pika H3 Flex model, it's very good!

Basically character swapping and motion transfer working out of the box with no lora needed!

Will be sharing workflows/details for this soon

Awesome demo!

Made with the char swap 1.5 lora by @akatz_ai

Very good for most situations, needs good input footage, some minor tweaks needed my mouse-eared characters, but overall amazing.
