You need to use the Rate Stretch tool because Premiere Pro sees the PSD file as more of a video clip than a still image. With the Rate Stretch tool, stretch Washington_ ref_2001/weatherMap.psd to match the duration of weatherReport.mp4 ( Figure 4.4).
For example, put a green screen clip on V2 so that you can put the new background under it on track V1.ĭrag the weather map graphic, Washington_ref_2001/weatherMap.psd, to track V1 at the beginning of the clip. In the Timeline panel, drag the green screen clip, weatherReport.mp4, to a higher track.
Although it is possible to simply have Premiere Pro remove the background based on the green color, using an opacity mask quickly masks off the areas that never need to be shown at any point in the clip, reducing the amount of potential variation in the green screen color and making background removal easier and faster. The first phase of green screen compositing is to draw an opacity mask, which is traditionally called a garbage matte. Now you’re ready to remove the green screen, revealing the weather map underneath.
