It sure looks like something is snagging the threads in the fabric weave. Puckering is seen coming in from the sides of the fabric as well as bunching up at the outfeed. Perhaps the needle type is not compatible with this fabric, and it is pushing the weave down to where it is getting caught. When I watched the video the first time, I thought thread tension, but after watching several times, it is obvious that the machine isn’t even threaded.
