SVI extend video

Added v2.0

Updated the workflow to support the latest nightly build of the Wan22FMLF node (commit 7140cd2). In my testing, the node now improves the momentum carried over from the previous latent, resulting in much smoother transitions now. You should update the node to use v2 workflow.

Added v1.0.1

• Display stitched result on each segment.

Added single extend version,

• It lets you extend the video infinitely (one segment at a time) by feeding the last output back in. Max 81 frames or 5 seconds extend

I’ve been using Stable Video Infinity (SVI) to extend existing videos for couple of days, and honestly it’s pretty impressive for what it’s trying to do. Instead of generating a whole video from scratch, my workflow approach focuses on taking an already existing clip and continuing it forward in a more coherent way and It can be used with loras and different prompt on each segment. All download links for required Models is on the workflow.

1. Load your video you want to extend

2. Input the steps (minimum 4 steps using lightx2v speed loras) and resolution

3. Input the length (max 81 frames)

4. Input the prompt and loras

5. Profit

Use CFG > 1 and 20 steps if you are not using speed loras,

Euler Simple is fine most of the time

Required Custom Nodes for the workflow, you can install through Comfyui Manager :
