Wan 2.2 I2V workflows that allow longer video generation by passing the last frame of one video as the input into the next. It then combines the videos at the end. Includes Lora loader node, SageAttn node, FP16 accumulation node in addition to the standard I2V nodes.If you can run the default Wan workflow, you should be able to run this as well. I noticed minimal, if any, additional overhead using this method. As with any extended video, context drift is possible. This workflow is best suited for actions where major changes to the scene aren't prompted.

Wan 2.2 I2V Extended Video

WAN Long-Form Workflow – Version 2 ChangelogMajor New Features• Unified workflow (5s / 10s / 15s) A single workflow now handles all durations. Easily switch between 5-second, 10-second, and 15-second generation using a toggle box.• Modular feature toggles Added multiple toggle boxes to enable or disable key features across the workflow.• Optional RIFE interpolation RIFE interpolation is now integrated and fully optional. Enable it for smoother motion and 30fps output, or disable it for a faster pipeline.• Per-segment positive prompting Each 5-second segment now has its own optional Positive Prompt box. This allows evolving actions, scene changes, or motion direction across segments.• Smart prompt fallback logic Don’t want to write multiple prompts? No problem. Toggles allow you to disable the Segment 2 and/or Segment 3 prompts. When disabled, the workflow automatically reuses Prompt #1 for all segments.Quality of Life Improvements• Pipeline cleanup with Set/Get nodes Replaced the majority of spaghetti wiring with Set/Get nodes, dramatically improving readability and reducing visual clutter.• Clustered control panel Many adjustable settings are now grouped together for ease of use and quick adjustment.• Resolution selector added A single Width/Height selector now controls resolution for all samplers, eliminating the need to change settings manually in multiple nodes.• Enlarged preview nodes Source Image and Output Video nodes are now larger and easier to read for quick visual checking.• General layout housekeeping Improved alignment, node spacing, routing, and organization for a cleaner, more professional workflow experience.• Built-in Help Panel A simple instruction box has been added to the top of the workflow to help new users understand setup, toggles, and intended usage.
