first frame - last frame video gen model and workflow for 5090

Hi, i am sorry for this kind of post but due to personal life i cannot follow ai scene as much as i want. and for a project i need to create a few videos (realistic, NOT HUMAN, scenery, cats etc) STRICTLY SafeForWork videos but i couldnt find a good enough workflow and model for it. I will loop the videos again and again so i assumed if i find a first frame - last frame workflow i could simply place the same image and they would be perfect? can anyone direct me towards something? any suggestions? edit: just incase, i have a 5090, 13700k and 128gb ddr5 submitted by /u/ares0027 [link] [comments.
