Ok so I'm in the middle of making a deployment video and all of a sudden I can't preview any of the clips or even the video. Then after a while I can preview the clips but still not the video in the making. Does anyone know what I might have done wrong or even if there is a way to refresh the video. I was able to preview the video just fine and the ladt thing I did before it took a dump on me was transition a few slides after a video clip.
