It accepts <code>width</code>, <code>height</code>, and <code>length</code> to set video size and duration, then emits a latent sequence plus updated positive/negative conditioning. Start here when tuning continuity, pacing, or composition across the shot.</p><h3 id="unetloader-(101-102)"><code>UNETLoader</code> (#101, #102)</h3><p>Chooses the Wan 2.2 Fun Inpaint model variant. Use <strong>high noise</strong> for bolder motion and more transformative interpolations. Use <strong>low noise</strong> when preserving the start and end frame identity and texture is the priority. Pair either with or without the 4-step LoRA depending on speed needs.</p><h3 id="modelsamplingsd3-(93)"><code>ModelSamplingSD3</code> (#93)</h3><p>Configures the sampler schedule used downstream. Keep it aligned with the chosen LoRA or fp8 path. If you see temporal flicker, modest adjustments to the sampler mode or steps can smooth transitions without over-sharpening details.</p><h3 id="ksampleradvanced-(150)"><code>KSamplerAdvanced</code> (#150)</h3><p>Applies a refinement pass to the latent sequence. Increase steps slightly if you need crisper micro-detail on faces, hands, or thin structures; reduce steps for softer, dreamier motion. Avoid extreme CFG or step counts that can destabilize temporal consistency.</p><h3 id="vhs_videocombine-(159)"><code>VHS_VideoCombine</code> (#159)</h3><p>Merges rendered frames to MP4. Adjust <code>frame_rate</code> for motion feel and playback speed, and keep the default <code>pix_fmt</code> for broad player compatibility. Lower CRF yields larger files with finer gradients; higher CRF compresses more aggressively.</p><hr /><h3 id="notes">Notes</h3><p><strong>ComfyUI Wan2.2 Fun Inp Workflow | First-to-Last Frame Interpolation</strong> — see <a target="_blank" rel="ugc" href="https://www.runcomfy.com/comfyui-workflows/comfyui-wan2-2-fun-inp-workflow-first-to-last-frame-interpolation?utm_source=civitai&amp;utm_medium=referral">RunComfy page</a> for the latest node requirements.</p>
