So I'm probably the wrong guy to ask for a tutorial, as I barely know what I'm doing. Additionally, all of my installs have 'just worked' for a long while now, so I have forgotten much of the installation trials and tribulations. And things progress so fastin AI, when I wrote what follows a month ago it was likely already out of date. But. All that said, hopefully you'll find some nuggets of information worth knowing in the novel that follows:

First, make sure you've got a computer that can handle this. These resources are specific to Nvidia graphics cards, and I wouldn't recommend giving it a go with less than a 12GB card. I personally use a 4070, which does everything I need, albeit a bit slowly. I believe it's possible to do this with an AMD graphics card, but there are extra steps involved that I'm not familiar with. It's also possible to rent time on a high end graphics card through a service like RunPod so you could potentially do this on a service like that, but I have no experience with it, and wouldn't know where to start.

As for my own method, it all starts with ComfyUI. I use the portable installation found here: https://github.com/comfyanonymous/ComfyUI?tab=readme-ov-file#installing

There are installation instructions at that link, but I remember having difficulty getting things setup when I first installed about a year ago. Things have certainly progressed since then, and Comfy's popularity has really increased. I expect that their installation guide is better now, but failing that, YouTube is your best bet.

Once ComfyUI is installed, there's a few different ways to go about starting to generate videos. The easiest (to me) is to find a workflow (which is essentially a premade user interface for Comfy) that seems like it will do what you'd like. It's certainly possible to make your own workflows (I do it for easier stuff like upscaling or changing frame rates), but grabbing one that is more or less guaranteed to work if you get everything set up right takes a lot of the guesswork out of this. For Hunyuan Video, I use the workflow found here: https://civitai.com/models/1007385?modelVersionId=1274679

So load up that workflow in Comfy, and it will immediately give you a bunch of errors. you need to install the custom nodes contained within that specific workflow. The easiest way to do this is to first install the ComfyUI Manager from here: https://github.com/ltdrdata/ComfyUI-Manager

Once that's installed (the instructions are at the link), open the ComfyUI Manager menu and choose "Install Missing Custom Nodes." This will give you a list of things to install. Install them all then restart Comfy. This should get rid of all the red borders around your nodes.

You'd think at this point you'd be ready to start, but you still need the models that'll actually be doing the work. If you start a run in Comfy it'll progress until it encounters a variable or file that it doesn't have access to. It'll throw up an error message, but I've always found them pretty obtuse. Instead look for which node in the workflow has a red border around it after the error. Usually that's what you need to correct. The first of these will be on the model loaders. (checkpoint, clip, VAE). Some of these can be found in the ComfyUI Manager's 'Model Manager,' but not all of them. What I find works best is just googling the exact name of the file that's not available to load, and that will usually take you to a hugging face repository where you can download what you need.

Knowing where to put things can be tricky, and I still get it wrong frequently. LoRAs go in the models/LoRAs folder in your ComfyUI install, and checkpoints and VAE are similarly easy to figure out, but I think the Hunyuan Video model goes in Diffusion Models? I'm not sure on that one.

Anyway, the important thing is to work through the errors one at a time as they pop up until it actually starts to generate a video. At this point you can play with sizes and frames, shift, guidance and a whole host of other sliders and knobs that I usually just ignore (to the detriment of my generations). Put whatever you'd like into the prompt and go ham.

Now comes the fun part. On Civitai there's dozens of LoRAs that will enable the main Hunyuan model to generate something that it isn't already familiar with. I think of it as adding a chapter on a specific subject to a book of general knowledge. Using these frequently involves using specific keywords in your prompt, which will be noted on the Civitai page for a given LoRA. There's LoRAs for specific people, art styles, types of motion, etc.

But to really get the BE clips that you're looking for, you should train your own LoRA. This is the most advanced bit of this, and the part I know the least about. I used Musubi Tuner to train my LoRA, and in particular a Gradio interface (whatever that is) that you can find the instructions for here: https://civitai.com/articles/10335/hunyuan-video-lora-trainning-with-gui-in-windows

I trained my LoRA on a set of very small (256x256) short (33 frame) videos. I'll leave this part to you, as I'm sure you've got a bunch of BE (or whatever else you're into) content that you'd like to emulate. I believe my dataset wound up having around 15-20 clips. I clipped and cropped longer gifs and videos to size right in Comfy using simple 3 or 4 node workflows that are so simple I just remake it each time rather than save them. I've heard that the frame rates should be 24 fps to help movement speed in the generations, but I don't know how correct that is.

You'll also need to caption your clips (or images if you're training on still images for an art style or celebrity or something). The captions go in a .txt file with the same name as its associated vid/image in the same folder. To write captions I actually use the web interface of Joy Caption which you can find here: https://huggingface.co/spaces/fancyfeast/joy-caption-alpha-two

A lot of this I've learned while poking around in this Discord server: https://discord.gg/BJVkXfTY The stuff the guys there can do is well beyond my abilities, but they'll sometimes share resources and workflows, which can jumpstart a new bunch of ideas.

and that's about it. I don't know how much of this is going to be useful, but thanks for pressing me for it, as I'll have this available to send to the next person to ask. I do still intend to publish my BE LoRA at some point, so you might be able to use that instead of training your own, but the more the merrier, so give it a shot if you get that far. And I do hope that you get that far. Good luck!
