This is a pruned version of my <a rel="ugc" href="https://civarchive.com/models/1416594/wan-aio-vace14bphantom">AiO workflow</a>.TL;DR: Seamless motion, but not colors. There are attempts to fix colors. Infinite extension. Loop. Long video generation (set it 20 sec or longer and go).The main idea is to take certain amount of frames from existing video and use them with VACE to continue motion seamlessly. Unfortunately, it often creates color mismatch, and there are multiple options in wflow to fix that. If none of them work, only v2v remains.There are two parts.First is video extension - takes set amount of last frames from input video and uses them as beginning of new one. There is an option to set length of a long video (for example 20 sec), and wflow will generate it by parts.Second part is video 'inpaint' for the lack of the better term - it fills the gap between two videos. Similar to first part, it takes the ending of first video, but also the beginning of a second, places them in start and end of new video and lets VACE work through it. It's the best option so far to create seamless loops, with ~80% success rate.Both wflows are present in group node variant (native only), and can be used as I2V or FLF2V if overlap/outro lengths set to 0 - then a single frame will be taken as reference.
