Glitchy Video Output

The program use to work, for some reason now the videos being outputted are really glitchy and not smooth. I am fairly experinced with taking timlapse videos and compliing them. Also on a new macbook pro, so hardwear isnt an issue. Anyways, Time_lapse use to work but is not longer for me.
