Hello everyone! I'm very new to Premier Pro (this is my second video) and I've run into a problem. When I went to export my video it is asking me to either stretch or fit to fill, and if I don't it has the ugly black bars on it. I noticed too that when I was adding my videos I had to stretch each individual one to make it fit into the playback screen appropriately so I'm assuming the two problems are related. Any ideas on what could have happened? I didn't have any of these issues with the first video so not sure if a setting accidentally got bumped?
Welcome to the community! This could happen because the frame size of your source videos and Sequence don't match. If you don't want to scale your source video and want to change the sequence frame size instead, you can do so by going to Sequence> Sequence Settings. When you drag a video to an empty Timeline, Premiere Pro adjusts the Sequence Settings according to the Source video. This might be why you didn't experience this issue the first time.
