Extend / continue a video temporally with Pusa 2.2 in ComfyUI. Temporal flowmatching (the flowmatch_pusa scheduler + WanVideoAddPusaNoise) on the WanVideoWrapper stack with WAN 2.2 T2V A14B (HIGH/LOW) models and the Pusa V1 LoRAs, conditioning on the loaded clip via WanVideoEncode so the existing motion carries into the continuation. Covers the kijai wanvideo_2_2_14B_Pusa_extension graph, model/LoRA slots + downloads, noise/length/scheduler settings, chaining multiple extensions, VRAM tiers, gotchas, and the extend→upscale handoff.

# Video Extension (Pusa 2.2 — temporal flowmatching)
## Overview
Pusa extends a video temporally. It continues and lengthens an existing clip
rather than regenerating it from scratch. It does this on the
ComfyUI-WanVideoWrapper stack (kijai) using the WAN 2.2 T2V A14B dual
HIGH/LOW models you already have for `wan-t2v-video`, plus the small Pusa V1
LoRAs and a Pusa-specific sampling path: the `flowmatch_pusa` scheduler and
the `WanVideoAddPusaNoise` node. The input clip is encoded with
`WanVideoEncode` and injected as the first latents of the generation, which
is what carries the existing motion and content into the continuation.
The official reference graph is kijai's
