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
Little UPDATE!
*The SVI node used in this workflow changed in the latest nightly build (commit 7140cd2). I'm still testing it, so if you're using latest commit (7140cd2), the workflow may produce different results. If you're on (712c82b) don't update it to (7140cd2) yet.

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
