V2:

More optimized, a few more settings added, some pointless nodes removed, and overall a better workflow. Also added in optional Flux group if you want to use that instead of XL

Added in also some help with Teacache (play around with that for speed, but don't go crazy with the thresh..small increments upwards)

Anyhow, give this a shot, its actually pretty impressive. I am not expecting much difference between this vs whenever they come out with I2V natively...(hopefully theirs will be faster though, the depthflow step is a hangup)

Thanks to the person who tipped me 1k buzz btw. I am not 100% sure what to do with it, but that was cool!
Anyhow

(NOTE: I genuinely don't know what I am doing regarding the HunyuanFast vs Regular and Lora. I wrote don't use it, and that remains true if you leave it on the fast model..but use it if using the full model. Ask for others, don't take my word as gospel. consider me GPT2.0 making stuff up. all I know is that this process works great for a hacky image2video knockoff)

XL HunYuan Janky I2V DepthFlow: A Slightly Polished Janky Workflow

This is real Image-to-Video. It’s also a bit of sorcery. It’s DepthFlow warlock rituals combined with HunYuan magic to create something that looks like real motion (well, it is real motion..sort of). Whether it’s practical or just wildly entertaining, you decide.

Key Notes Before You Start

Denoising freedom. Crank that denoising up if you want sweeping motion and dynamic changes. It won’t slow things down, but it will alter the original image significantly at higher settings (0.80+). Keep that in mind. Even with 80+, it'll still be similar to the pic though.
Resolution matters. Keep the resolution (post XL generation) to 512 or lower in the descale step before it shoots over to DepthFlow for faster processing. Bigger resolutions = slower speeds = why did you do this to yourself?
Melty faces aren’t the problem. Higher denoising changes the face and other details. If you want to keep the exact face, turn on Reactor for face-swapping. Otherwise, turn it off, save some time, and embrace the chaos.
DepthFlow is the magic wand. The more steps you give DepthFlow, the longer the video becomes. Play with it—this is the key to unlocking wild, expressive movements.
Lora setup tips.
- Don’t touch the FastLoRA—it’s broken garbage and will turn your video into a grainy mess.
- Load any other LoRA, even if you’re not directly calling it. The models use the LoRA’s smoothness for better results.
- For HunYuan, I recommend Edge_Of_Reality LoRA or similar for realism.
XL LoRAs behave normally. If you’re working in the XL phase, treat it like any other workflow. Once it moves into HunYuan, it uses the LoRA as a secondary helper. Experiment here—use realism or stylistic LoRAs depending on your vision.

WARNING: REACTOR IS TURNED OFF IN WORKFLOW!
(turn on to lose sanity or leave off and save tons of time if you're not partial to the starting face)

How It Works

Generate your starting image.
- Be detailed with your prompt in the XL phase, or use an image2image process to refine an existing image.
- Want Flux enhancements? Go for it, but it’s optional. The denoising from the Hunyuan bit will probably alter most of the Flux magic anyhow, so I went with XL speed over Flux's clarity, but sure, give it a shot. enable the group, alter things, and its ready to go. really just a flip of a switch.
DepthFlow creates movement.
- Add exaggerated zooms, pans, and tilts in DepthFlow. This movement makes HunYuan interpret dynamic gestures, walking, and other actions.
- Don’t make it too spazzy unless chaos is your goal.
HunYuan processes it.
- This is where the magic happens. Noise, denoising, and movement interpretation turn DepthFlow output into a smooth, moving video.
- Subtle denoising (0.50 or lower) keeps things close to the original image. Higher denoising (0.80+) creates pronounced motion but deviates more from the original.
Reactor (optional).
- If you care about keeping the exact original face, Reactor will swap it back in, frame by frame.
- If you’re okay with slight face variations, turn Reactor off and save some time.
Upscale the final result.
- The final step upscales your video to 1024x1024 (or double your original resolution).

Why This Exists

Because waiting for HunYuan’s true image-to-video feature was taking too long, and I needed something to tinker with. This (less) janky process works, and it’s a blast to experiment with.

Second warning:
You're probably gonna be asked to download a bunch of nodes you don't have installed yet (DepthFlow, Reactor, and possibly some others). Just a heads up.

Final Thoughts

This workflow is far from perfect, but it gets the job done. If you have improvements, go wild—credit is appreciated but not required. I just want to inspire people to experiment with LoRAs and workflows.

And remember, this isn’t Hollywood-grade video generation. It’s creative sorcery for those of us stuck in the "almost but not quite" phase of technology. Have fun!
