I'm working on a project where I have a jpeg with a video clip on either side with a transition into and out of it. I've now found that the time length of the image is too short and want to extend it. To do this I've moved the video clip to remove the transition and add some space to lengthen the image and then moved the video clip back and put the transition back in (hope this makes sense). Is there a quicker way to do this as I need to perform this task a few times?

Thanks
