<h1 id="bxr-i2v-upscaler-and-interpolation-wan-2.2-(v2-refresh)">BXR - I2V Upscaler &amp; Interpolation - WAN 2.2 (V2 Refresh) 👑</h1>Thanks to everyone who has supported the page recently and helped hit the 1k milestone! To give back, I’m releasing BXR I2V ULTRA v2.0.This is my dedicated ComfyUI workflow for taking Image-to-Video generations to the absolute maximum quality. It’s designed to be powerful right out of the gate, but modular enough for you to customize it to your own style.Key Features:<ul><li>The "Get Started" Node: I've built in a node that will directly download everything you need to run this on my personal standards. No hunting for the baseline models.</li><li>Total Flexibility: Want to bring your own models, LoRAs, or upscalers to the table? The workflow is cleanly sectioned so you can easily swap in your preferred assets.</li><li>Built-in Enhancement: Integrated RIFE frame interpolation and high-fidelity upscaling (configured for Remacri) to ensure your final outputs are buttery smooth and crisp.</li></ul>How to Install &amp; Use:<ol><li>Download the <code>.json</code> file attached to this post.</li><li>Open ComfyUI.</li><li>Simply drag and drop the <code>.json</code> file directly onto your ComfyUI workspace to load the workflow.</li><li>Run the "Get Started" node to pull the required models, or hook up your own.</li></ol>⚠️ IMPORTANT WARNING: ComfyUI V2 Desktop / Node 2.0 This workflow is NOT built on Node 2.0 yet. I have not tested it within the new V2 mode, so please use it with caution or stick to the standard ComfyUI interface to ensure stability.Enjoy the workflow, and drop your best generations in the reviews!<h3 id="dependencies-and-models">Dependencies &amp; Models</h3>Custom Node Suites Identified:<ul><li>WanImageToVideo: Required for the core Wan2.1 I2V generation (<code>WanImageToVideo</code> node).</li><li>ComfyUI-Easy-Use: Required for the VRAM management (<code>easy cleanGpuUsed</code> node).</li><li>ComfyUI-Frame-Interpolation (or similar FL RIFE suite): Required for the frame smoothing (<code>FL_RIFE</code> node).</li><li>ComfyUI-VideoHelperSuite: Required for processing and exporting the final media (<code>CreateVideo</code> and <code>SaveVideo</code> nodes).</li></ul>Models, LoRAs, and Checkpoints Referenced:These are included in the "Get Started" Node.<ul><li>Diffusion Models: <code>DasiwaWAN22I2V14BLightspeed_snatchkissHighV11.safetensors</code> and <code>DasiwaWAN22I2V14BLightspeed_snatchkissLowV11.safetensors</code></li><li>LoRAs: <code>DR34ML4Y_I2V_14B_HIGH_V2.safetensors</code> and <code>DR34ML4Y_I2V_14B_LOW_V2.safetensors</code></li><li>CLIP/Text Encoder: <code>umt5_xxl_fp8_e4m3fn_scaled.safetensors</code></li><li>VAE: <code>wan_2.1_vae.safetensors</code></li><li>Upscale Model: <code>4x_foolhardy_Remacri.pth</code></li><li>Interpolation Model: <code>rife49</code></li></ul>

BXR - I2V Ultra - Upscale & Interpolation - WAN 2.2

v2.0 Version Notes / Changelog<ul><li>Wan 2.1 Architecture Integration: Fully updated to support Wan 2.1 VAE and FP8 scaled CLIP models.</li><li>Dual-Stage Sampling: Implemented a split KSampler workflow (Steps 0-4 and 4-8) for precision generation control.</li><li>Advanced Model Routing: New dedicated pathways for High/Low diffusion models paired with updated V2 LoRA routing.</li><li>Optimized Post-Processing Engine: Streamlined FL RIFE frame interpolation (set to a 4x multiplier) and 4x Remacri upscaling for maximum fidelity.</li><li>Improved VRAM Management: Added VRAM clearing nodes between the generation and post-processing stages to prevent out-of-memory errors during heavy upscales.</li></ul>
