I am just seeing your thread. Sounds like you are making progress with your green screen Premiere Elements project.
Please remind me what is the format for the background file on Video 1. Is it still or video? My recollection is that it is a still. If that is the case, the mouse click and drag out to the wanted duration should do the job. The longer way and more exact way would be to right click the Video 1 still clip, select Time Stretch, and then set the exact duration in the Time Stretch dialog which shows duration in a timecode fashion 00;00;00;00 (hours; minutes/seconds/frames).
If the mouse click drag did the job, then great.
