This will improve video quality and<h2 id="how-it-works-for-me">How it works for me</h2>Generating video at 16 frames per second. I usually use 45-55 frames generation for this.I get about 3-3.5 seconds of video (49fps/16f=3.06s). The generated frames are then sent for x2 interpolation. At the end I get a smooth 4-5 seconds video at 24 frames per second (orig49f*2=98f/24fps=4.08s got smoothness and 1 second of video)x2 interpolation completes one frame between two original frames. If you want to increase the multiplier, it must be a multiple of 2. A multiplier of 4 will draw 2 frames between the two original frames.I don't use multiplier 4 because there is a risk to get slowmo effect.I've found the perfect setting for me.For KSampler:<ul><li>steps 22-35</li><li>cfg 4-5</li><li>sampler: uni_pc</li><li>sheduler: simple</li><li>denoise 0.95-1</li></ul>I have RTX 5060 16Bb, 64Gb RAM, i5 24600KF. Stable average generation time of a 4 second video 1000-1300 seconds.It all depends on the image size and steps in KSampler. I mostly work with 512*512 and 480*720This is my first workflow that gives normal quality and speed. At least I'm happy with it.Try it. I hope I could help someoneP.S. I will keep working on this workflow, let me know if anyone is interested in it.
