Hi there. I want to zoom into a section of video, hold the image on that section for a while and then move away to another section before returning to full screen. I assume I need to cut the video into clips and apply an effect to each, but how do I make sure that the start point of the next clip is the same as the end point of the previous one so I avoid a 'jump' as I move between clips / effects?  At the moment all I can do is guess the positioning and use trial and error to get it right.

Sorry, I hope this makes sense but zoom, section and size and position seems very complicated and I find it impossible to see what I have done once I have done it so I have to keep clearing all effects and starting again. Thank-you.  Any tips at all on zooming would be very much appreciated.
