continuity exercise by Aaron and Sam Questions

we achieved continuity for most of the clip but at one point when aaron walks up the stairs and meets sam there is a slight jump, this is because aaron slows down as he reaches the top of the stairs but the next clip the aaron has a faster pace in his walk, this creates a jump, we tried to fix this by extending the clip to keep them at the same pace. The skills we learnt last week (focus, white balance and exposure)where used in each shot to make it look right. our shots where framed correctly, we used a lot of mid shots getting the wast up shot of the subject, there are a few long shots getting the full length on subject. This short film  could be improved by shooting the scenes multiple times to get the best looking shot.
