How to Crop Video without Losing Quality?

“I have an MP4 video of 3840x2160. I would like to crop the video to 1920x1080 without quality loss. Does anyone know how I can crop the video without losing the quality?”

The bad news is that no matter what method you try, quality loss is inevitable when cropping videos. There are two main reasons for this:

1. The pixels will lose.
2. The video will be re-encoded.

Cropping a video removes part of the video and therefore makes it smaller in size. If you were to display the cropped video in its original size, you would easily notice the loss of video quality. It's like zooming in on a video and you see everything is blurry. At the same time, video cropping involves re-encoding, so the quality is again reduced.

It's impossible to crop a video without losing any quality, but you can minimize the loss. The solution is to encode the video using efficient codecs like H264 and HEVC and export the video as-is without upscaling. In the next section, you can learn more about how to crop videos with minimal quality loss.
