asking to predict every pixel you know in a bunch of frames in a video which is a lot of information much more than the label of a of an image for example which means you're putting a lot more constraints on the parameters of the machine which means you can train the machine to learn a lot of knowledge with a relatively small number of samples and furthermore those samples are free because you know we have more video data than then we can deal with so essentially if you think about sort of a hierarchy of the type of loading paradigms that we've
