Let's say I import a video (and let the Media Encoder make a proxy to be able to work with the video) and cut out a small part of the video in the middle. I then paste it in the timeline in Premiere Pro. I then want to export this cutout, but when I go to the export window the part that I cut out (which is in my timeline) is not there, instead of a clip from the beginning of the source video is shown (also the duration of the clip is the exact same as my cutout). Why does this happen?? Is it something common that can be easily fixed?
