Apache 2.0v3.0 update!
When opening the workflow, set your start image and video first!
New features include:
- Removed clutter
- Eliminated all custom nodes dependency besides the most essential three:
ComfyUI-KJNodes
ComfyUI-Easy-Use
rgthree-comfy
And ComfyUI-Lora-Manager for the LoRA stackers
A simple workflow for "infinite length" video extension provided by SVI v2.0 where you can give infinite prompts - separated by new lines - and define each scene's length - separated by ",".
Put simply, you load your models, set your image size, write your prompts separated by enter and length for each prompt separated by commas, then hit run.
Detailed instructions per node.
Load video
If you want to extend an existing video, load it here. By default your video generation will use the same size (rounded to 16) as the original video. You can override this at the Sampler node.
Selective LoRA stackers
Copy-pastable if you need more stacks - just make sure you chain-connect these nodes! These were a little tricky to implement, but now you can use different LoRA stacks for different loops. For example, if you want to use a "WAN jump" LoRA only at the 2nd and 4th loop, you set "Use at part" parameter to 2, 4. Make sure you separate them using commas. By default I included two sets of LoRA stacks. You can overlapping stacks no problem. Toggling them off or setting "Use at part" to 0 - or a number higher than the prompts you're giving it - is the same as not using them.
Load models
Load your High and Low noise models, SVI LoRAs, Light LoRAs here as well as CLIP and VAE.
Settings
Set your anchor image, generation width / height.
Give your prompts here - each new line (enter, linebreak) is a prompt.
Then finally give the length you want for each prompt. Separate them by ",".
Sampler
Sampling settings (steps for high/low, seed, cfg).
"Use source video" - enable it, if you want to extend existing videos.
"Override video size" - if you enable it, the video will be the width and height specified in the Settings node.
"Override anchor image" - it will use the image you loaded in Settings even if you're extending video - useful when trying to avoid quality degradation or having a bad anchor for the video's last frame.
