Once the video have finished generating, you can change and set the Interpolation Multiplier and/or select Interpolate + Upscale option and click ComfyUI RUN button again which will skip the Sampling process/steps because you are using the same seed number and Not change any inputs that is not in the Post Processing Section.To generate a new seeded video, click on "New Fixed Random" in the seed node and click on the ComfyUI RUN button.This method also speed up drafting for videos, so you don't waste time interpolating or upscale the video you might not want.Small written guide in WF.17/7 - Added 🟩 Single Sampler Workflows V2.1 to use with the new Self-Forcing(Lightx2v) Lora.Single Sampler Downloads Contains the following WF:<ul><li>Expanded (Shows all connections - mainly for learning + exploration)</li><li>Compacted (Only show essentials and hides everything else)</li><li>Simplified ("Standardized" WF for those who prefer to have more control over inputs)</li><li>Interpolation + 2x Upscaler (Useful when you want to generate a lot of videos until you get the desire one and interpolate+upscale later. )</li><li>Joiner/Merger (Joins 2 videos together)</li></ul>This Single Sampler workflow includes:<ul><li>GGUF Loaders for Diffuser Model + Clip (Best to use GGUF Model + Clip together)</li><li>Block Swap for memory management</li><li>Sage Attention (Speed up Generation Time) - I forgot how I managed to install this.</li><li>Torch Compile (Speed up Generation Time) - Enable only when your system support it.</li><li>NAG (Normalised Attention Guidance) - Adjusts negative prompt influence intelligently when using CFG 1.</li><li>Stack Lora Loader</li><li>Scale by Width for Image Dimension Adjustment</li><li>Video Speed Control</li><li>Frame Interpolation for Smoothing</li><li>Auto Calculation for Numbers of Frames and Frame Rates in accordance to the inputs of video length, speed and interpolation multiplier</li><li>Save Last Frame (For sequencing video)</li><li>Color Match (Useful for sequencing video or uniform color through out video)</li><li>VRAM - Clean-up</li><li>Upscaler (up to 2x)</li></ul>5min 30sec generation time on my 3090 Ti 24 GB:<ul><li>720x960 Image - 4 steps - 81 frames (5secs) - 4x Interpolation - Upscaler - GGUF - Torch Compile - Sage Attention</li></ul>Videos posted above are without speed adjustment.Includes Embedded Workflow.

(too much motion, color change, sudden exposure), lower down the Start CFG. Alternate between 3 &amp; 5 to see which is better.Some videos I posted above used lower CFG because the other loras are too aggressive with high CFG level.</li></ul>Drafting for motion with other Loras:<ul><li>Use smaller image dimension for faster generation to see if the lora you use have any motion.</li><li>Once satisfied with lora and prompt proceed to use desire image dimension.</li></ul>Other tips:You can also clean up distortion/blur by using other V2V workflow.Like this one:<a target="_blank" rel="ugc" href="https://civarchive.com/models/1714513/video-upscale-or-enhancer-using-wan-fusionx-ingredients">https://civarchive.com/models/1714513/video-upscale-or-enhancer-using-wan-fusionx-ingredients</a>and/or use face swap to clear face distortions.<hr /><h1 id="dual-ksampler">🟨Dual KSampler</h1><h3 id="recommended-steps:">Recommended Steps:</h3><ul><li>5 start steps / 3 end steps (I used the most for testing)</li><li>4 start steps / 3 end steps</li></ul>The old T2V Self-Forcing(lightx2v) may sometimes hinder, slow down or produce less motion for some loras.In order to get more motion for some loras, you need a higher CFG level of more than 1, but when using Self-Forcing(lightx2v), you need to set the CFG to 1.So this is when Dual KSampler is utilize.<ul><li>The 1st KSampler uses high CFG level of 3-5 to create better "motion latent" along with Causvid Lora to increase more motion with lesser step generation.</li><li>The 2nd KSampler uses low CFG of 1 for finishing the video with 3 steps using Self-Forcing(lightx2v) lora for speed generation. More steps count will make Self-Forcing(lightx2v) lora to influence the video more and cause lesser motion again.</li></ul>In order to pass "motion latent info" to the 2nd sampler, the 1st step count has to be more than half of the total steps.Examples:<ul><li>5 first steps / 3 last steps / 8 total steps</li><li>4 first steps / 3 last steps / 7 total steps</li></ul>When it is configure in this way, you can see the images start to form in the latent preview:<img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/f29312d2-aff0-4471-910e-65dc8addd539/width=525/f29312d2-aff0-4471-910e-65dc8addd539.jpeg" />That is when it can be pass to the 2nd KSampler with "motion latent info" to finish it off without heavily influencing it in low steps.(If the 1st steps count is half or less than half of the total steps, you will see a very noisy image that does not resemble anything.)Basically a 7-8 steps generation splits into 2 KSampler.The 2nd KSampler continue the generation process from where the 1st KSampler left off.(Using 2 normal samplers will not produce the same results as the 2nd sampler will not know at which step to continue from. It will take the product of the 1st KSampler, ignore what it has produce and start from step 0.)With the initial KSampler generating at 3-5 CFG, its slower. But the trade off here is to get more motion when using it with other loras. Comparing it to a 20-30 steps with no CausVid or Self-forcing(Lightx2v), it way faster.Unfortunately, KSampler with Start End Step is only available for Native and not WanWrapper.<hr /><h1 id="tooooo-many-get-and-set-nodes....">Tooooo many GET and SET nodes....</h1>!!!
