Re. #1: Yes, <picture> elements have an /animation attribute just like <shape> elements do, i.e. you can have a <picture> move from point A to B by using the points() function in its /animation attribute. Re. #2: Yes, you can control the point in time _when_ a given stimulus is displayed during a <trial> via the <trial>'s /stimulustimes attribute -- it does not matter whether the stimulus is a <text>, <picture> or <video>. <trial example> / stimulustimes = [0=fixation; 2000=sometextstimulus, anothertextstimulus; 5000=somevideo; ...] ... </trial> As for "replacing" a stimulus after a certain time, set up two stimulus elements, and then simply display the 2nd one over the 1st one at the appropriate time. This will work fine for static stimuli like <picture> elements, for <video>s it will depend on whether the 1st video is still running or not.
