After a number of SVI attempts, and wanting to include a FLF option, I have added my own take on a Wan 2.2 SVI workflow. This tries to keep things as "easy" and clean as possible while being as optimized for lower VRAM and Memory scenarios as possible.
I run this on 12 GB VRAM with 32 GB RAM - and I'm fairly confident it would run on an 8 GB VRAM card without any issues. The most important factor will come down to your RAM as your video card bottlenecks.
While this is created for GGUF, it can easily use any of the Wan 2.2 trained checkpoints as well - just change the UNET GGUF loader for a standard ComfyUI Load Checkpoint node. I do this most of the time as I prefer many of the trained checkpoints (FP8 version), due to fewer loras needed.
Included Modules in this workflow (install via the ComfyUI Manager - Custom Nodes Manager):
ComfyUI-KJNodes
rgthree-comfy
ComfyUI-Easy-Use
ComfyUI-Wan-SVI2Pro-FLF
ComfyUI-VideoHelperSuite
ComfyUI-Frame-Interpolation

Hi there,
First of all, thank you so much for creating and sharing this amazing workflow!
I am reaching out because I am unable to use the "first-to-last frame" setup in Scene 3. Besides not being very familiar with this method, I am running into installation issues with the required custom nodes. Due to some specific system security constraints on my end, I am restricted from installing certain nodes needed for this scene.
Would it be possible for you to modify Scene 3 to use the standard svi Image-to-Video (I2V) rendering process, exactly like how Scene 1 and Scene 2 are set up?
Thank you for the feedback!
The node issue is a security setup with ComfyUI for that node. If you lower the security, install that node, then reset your security it works ... but there is a reason it isn't authorized normally (the code looks ok, at least in my quick review - but that's still a lot of risk to take on).
For regular "non-first-to-last", you can simply delete "Scene 3" and copy "Scene 2" in entirety (nodes, and I like to keep the group frame when I do). I've done 6 scenes in a row with no FLF at all, and some longer ones with one. It is entirely how you want to set it up. Just make sure to put the outputs from your scenes into the new one - and check the instructions / notes at the top of the workflow.
I found the answer. It happened when I tried to install the nightly version, but it worked fine if I chose to install a different version.
