What aspect ratio should I use when cropping a video?

Does cropping a video reduce quality?
Cropping changes the frame and re-encodes the video during export. Starting with a high-quality source gives the cleanest result, and choosing only the area you need can also reduce the final file size.
What is the difference between cropping and trimming a video?
Cropping changes the visible frame, while trimming removes time from the beginning, end, or middle of a video. Use the video trimmer when you need to shorten the clip instead of changing what is visible.
