Im not an editor just doing a quick one off project - hopefully someone can help me?
when I export my project at 1280 x 720 (file>export>quicktime>current settings) a number of clips on my timeline are disappearing and the clips following them slide in to take their place. so theres not even any blank time where the clips were.
however if export with the sequence at 640 x 360 ( (file>export>quicktime>current settings>custom size)
the export comes out perfect.
all my clips on the timeline are 1280 x 720 - H.264 as is the sequence settings
