Does cropping a video reduce quality?
Cropping changes the frame and may slightly reduce quality. Start with a high-quality video for the cleanest result. Keeping 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.
