Self forcing is really bad and deteriorates video quality a lot. Dont recommend unless your "job" is extremely simple, like "the character smiles and then turns around"
My experiences are based on https://huggingface.co/lightx2v/Wan2.1-T2V-14B-StepDistill-C.... Are we talking about the same thing? I could not observe a clear degradation in video quality, quality got sometimes even dramatically better!
