Move a series of videos, titles, audios etc and insert an image

You don't have to drag them to the right, mcdon. If you drag your new clip into the middle of your project on the timeline (inserting) the video to the right of that insert will ripple right to allow for the insert.

I understand I can drag the clip to the right. I have a 30 min project consisting of many short segments of video clips, title pages, audios etc. To view them all on the screen several segments are very narrow. It is very difficult to ensure I click them all and then drag them to the right. If I zoom in on the time-line I cannot click the segments further to the right as they are not visible on the monitor. So I selected 'fit to visible timeline' and I managed to do it after about five or six attempts. I'm asking if there is a better way to do it.

Just drag the clip to the middle of your project (in Expert view). The program will split your project at the insert point and move the video to the right to allow you to insert the clip.
