<h2 id="wan2.1_14b_fusionx-merged-models-for-faster-richer-motion-and-detail-in-as-little-as-8-steps!">🌀 Wan2.1_14B_FusionX — Merged models for Faster, Richer Motion &amp; Detail in as little as 8 steps!</h2>📢 7/1/2025 Update!<h3 id="new:-fusionx-lightning-workflows">New: FusionX Lightning Workflows</h3>Looking for faster video generations with WAN2.1? Check out the new FusionX_Lightning_Workflows — optimized with LightX LoRA to render videos in as little as 70 seconds (4 steps, 1024x576)!🧩 Available in: • Native • Native GGUF • Wrapper (VACE &amp; Phantom coming soon)🎞️ Image-to-Video just got a major upgrade!!!!!! Better prompt adherence, more motion, and smoother dynamics.⚖️ FusionX vs Lightning? Original = max realism. Lightning = speed + low VRAM, with similar quality using smart prompts.👉 <a target="_new" rel="ugc" href="https://civarchive.com/models/1736052?modelVersionId=1964792">Check it out here</a><hr />☕ Like what I do? Support me here: <a rel="ugc" href="https://buymeacoffee.com/vrgamedevgirl">Buy Me A Coffee</a> 💜 Every coffee helps fuel more free LoRAs &amp; workflows!<hr />📢 Did you know you can now use FusionX as a LoRA instead of a full base model? Perfect if you want more control while sticking with your own WAN2.1 + SkyReels setup.🔗 Grab the FusionX LoRAs <a target="_blank" rel="ugc" href="https://civarchive.com/models/1678575?modelVersionId=1900357">HERE</a> 🔗 Or Check out the Lightning Workflows <a target="_blank" rel="ugc" href="https://civarchive.com/models/1681541?modelVersionId=1903803">HERE</a> for a huge speed boost.<hr />📌 Important Details- Please read the full description below because small changes to settings will provide totally different results in a bad way! I have been testing and already found better settings so just please read below! Thank you :)💡Workflows can be found <a target="_blank" rel="ugc" href="https://civarchive.com/models/1663553?modelVersionId=1882890">HERE </a>(This is a wip and more will be added soon.)🛠️Updates section has been moved to the end of the description.A high-performance text-to-video model built on top of the base WAN 2.1 14B T2V model — carefully merged with multiple research-grade models to enhance motion quality, scene consistency, and visual detail, comparable to some of the many close source models.## 📢 Join The Community!A friendly space to chat, share creations, and get support.👉 <a target="_blank" rel="ugc" href="https://discord.gg/hxPmmXmRW3">Click here to join the Discord!</a>Come say hi in <code>#welcome</code>, check out the rules, and show off your creations! 🎨🧠<h3 id="what's-inside-this-base-model:">💡 What’s Inside this base model:</h3><ul><li>🧠 CausVid – Causal motion modeling for better scene flow and dramatic speed boot</li><li>🎞️ AccVideo – Improves temporal alignment and realism along with speed boot</li><li>🎨 MoviiGen1.1 – Brings cinematic smoothness and lighting</li><li>🧬 MPS Reward LoRA – Tuned for motion dynamics and detail</li><li>✨ Custom LoRAs (by me) – Focused on texture, clarity, and fine details. (These both were set to very low strengths and have a very small impact)</li></ul><hr /><h3 id="highlights:">🔥 Highlights:</h3><ul><li>📝 Accepts standard prompt + negative prompt setup</li><li>🌀 Tuned for high temporal coherence and expressive, cinematic scenes</li><li>🔁 Drop-in replacement for WAN 2.1 T2V — just better</li><li>🚀 Renders up to 50% faster than the base model (especially with SageAttn enabled)</li><li>🧩 Fully compatible with VACE</li><li>🧠 Optimized for use in ComfyUI, With both the Kijai Wan Wrapper and native nodes.</li></ul><hr />📌 Important Details for text to video:<ul><li>🔧 CGF must be set to 1 — anything higher will not provide acceptable results.</li><li>🔧 Shift - Results can vary based on Resolution. 1024x576 should start at 1 and if using 1080x720 start at 2. Note: For more realism lower shift values is what you need. If your looking for a more stylized look then test higher shift values between 3-9</li><li>Scheduler: Most of my examples used Uni_pc but you can get different results using others. Is really all about experimenting. I noticed depending on the prompt that the flowmatch_causvid works well too and helps with small details.</li></ul>📌 Important Details for image to video:<ul><li>🔧 CGF must be set to 1 — anything higher will not provide acceptable results.</li><li>🔧 Shift - For image to video I found that 2 is best but you can experiment.</li><li>Scheduler: Most of my examples used dmp++_sde/beta and seems to work best but you can experiment.</li><li>After testing, to get more motion and reduce the slow-mo look, set your frame count to 121 and frames per second to 24. This can provide up to a 50% motion speed boost.</li></ul>📌Other Important Details:<ul><li>⚡ Video generation works with as few as 6 steps, but 8–10 steps yield the best quality. Lower steps are great for fast drafts with huge speed gains.</li><li>🧩 Best results using the Kaji Wan Wrapper custom node: <a target="_blank" rel="ugc" href="https://github.com/kijai/ComfyUI-WanVideoWrapper">https://github.com/kijai/ComfyUI-WanVideoWrapper</a></li><li>🧪 Also tested with the native WAN workflow, generation time is a bit longer but results match wrapper.</li><li>❗ Do not re-add CausVid, AccVideo, or MPS LoRAs — they’re already baked into the model and may cause unwanted results.</li><li>🎨 You can use other LoRAs for additional styling — feel free to experiment.</li><li>📽️ All demo videos were generated at 1024x576, 81 frames, using only this model — no upscaling, interpolation, or extra LoRAs.</li><li>🖥️ Rendered on an RTX 5090 — each video takes around 138 seconds with the listed settings.</li><li>🧠 If you run out of VRAM, enable block swapping — start at 5 blocks and adjust as needed.</li><li>🚀 SageAttn was enabled, providing up to a 30% speed boost. (Wrapper only)</li><li>Workflows for each model can be found here: <a target="_blank" rel="ugc" href="https://civarchive.com/models/1663553?modelVersionId=1882890">HERE</a></li><li>🚫 Do not use teacache — it’s unnecessary due to the low step count.</li><li>🔍 “Enhance a video” and “SLG” features were not tested — feel free to explore on your own. -- Edit. I did test "Enhance a video" and you can get more vibrant results with this turned on. Settings between 2-4. Experiment! SLG has not been tested much.</li><li>💬 Have questions?

I'm slowly adding to this list, but here you can see how the models compare against the main model.Text to video:<img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/31414604-de0f-471c-934b-11c537277fed/width=525/31414604-de0f-471c-934b-11c537277fed.jpeg" />--------🛠️Update 6/8/2025 - Image to video model is published! Settings that I use in the example videos: Steps = 10 / cfg = 1 / shift = 2 / schedular = dmp++_sde i'll post a WF soon.🛠️Update 6/7/2025 - Published a i2v phantom model that can take up to 4 reference images and combine them into a video. Posting workflow soonPhantom WF is getting uploaded soon.🛠️Update 6/6/2025 - Added a new gguf model! If you want the highest quality and have enough VRAM get the V1.0 model otherwise gguf is the next best thing! When using the gguf's it will take longer to generate even on an RTX 5090.
