Hello. I have a video file, which video size is 352x288. I import it into the premiere and after I export it, it is low quality and the video size is different. I tried to choose another video size (chose desktop) by typing it manually (exactly 352x288), but I still see two black borders and the quality doesn't make any difference. How would I possibly import and edit the video in its original quality (video size and video quality)? Thank you.
