I fold more like this except for the sides I do a 2 step fold. First fold is about 45 degrees, partially roll up burrito, second fold is full 90 degrees and then finish roll. In this video she is doing a multiple side folds/tucks but I only do 2. The way she folds in the sides is awkward. Use both hands to roll the burrito and stabilize it but just use pinky fingers to fold in the sides.
