agree with above, looks like you arent going slow enough, and perhaps arent moving the stick into the metal as it starts to disappear. By this I mean as your welding and the stick is melting into the job, it looks like your moving along the metal then moving back in with the stick, then moving along again, not doing both at the same time.
I dont stick weld often, I'd much perfer to Mig, but when I do stick I try to keep the motion as fluid as possible, slow and steady and all that stuff
I'm only a Diesel fitter but It all comes down to practice, I was fairly average at it when I started but just get some scrap metal and practice.
