SVI2Pro+FLFVideoExtension
Allows you to extend existing videos using keyframes.
SVI2PRO FLF V1.1
Added a switch to enable/disable end_samples (Last Frame) directly, without manually connecting/disconnecting inputs. This toggles the First/Last Frame functionality: if disabled, the node reverts to the base SVI 2 PRO behavior. (Requires updating the Wan-SVI2Pro-FLF nodes to the latest version)
Added contrast adjustment widget, useful if your output looks washed out.
SVI2PRO FLF V1
Workflow for ComfyUI that combines SVI 2 Pro motion continuity with Wan 2.2 First/Last Frame (FLF) style control over the end of a clip, enabling smooth video generation from a sequence of frames.
SVI2PRO VideoExtension
This workflow uses SVI 2 PRO to extend existing videos: just load your video, add a prompt, and watch it seamlessly generate the continuation.
3-Stage Loop Automation
Experimental: 3-Part Loop Mode
Uses 3 images (Start / Loop / End) and 3 prompts to automate sequences:
Start → Loop entry
Repeating loop action (varies per cycle if increment is enabled)
Loop exit → Final frame
Ensure prompts match their corresponding image transitions.

any reason why the prompt is not available? https://imgur.com/a/ihBJmNS
My guess is that ComfyUI changed how it handles subgraphs across versions. The prompt is easy to reconnect though:
- Right-click the subgraph
- Select "Edit Subgraph Widgets" from the menu
- Type "positive" in the search field
- Find "CLIP Text Encode (Positive Prompt)" and click the crossed-out eye icon next to it
@WhateverName tried that but didn't work, looks to me like the latest update messed with something.
@skyrimer3d I've updated ComfyUI to see what they've broken this time. My previous instruction indeed isn't working anymore, but I found another solution.
Inside the subgraph, expand the Positive Prompt node (the green one) by clicking the grey dot on its left side. Type something into it, and the prompt input will appear on the subgraph.
FLF V1.1 right now is extremely washed-out to the point of simple contrast change wont fix it, even the first frame looks nothing like it, I add 1.2 contrast + color match node and still broken looking nothing like it.
it misses the point of a frame2frame if none frames looks nothing like the provided images.
What models are you using?
@WhateverName i used exactly the same on your workflow 1:1 didnt change a thing
