Does Cropping a Video Lower 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?”

Cropping is a common technique in video editing. However, no matter what method you try, quality loss is inevitable when cropping videos. Why does cropping reduce quality? Two main reasons:

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

Just like cropping an image, you are removing the portion of the video that contains the pixels used to fill the original frame. If you were to display the cropped video at its original size, you might quickly notice a drop in quality. Like when you zoom in or enlarge a video you will see everything becomes blurry. On the other hand, video cropping as well as many other video editing involves re-encoding and quality loss will occur again.

There is no way around this. But if you accept some quality loss, you can try to reduce the damage to the point where you can't even see the difference. A possible solution is to encode the video with high-efficiency codecs like H264 and HEVC, and export the video as-is without upscaling. In the next section, you can learn more details about how to crop a video with minimal quality loss.

You can preview the real-time effect on the right “Output Preview.” Also, you can click "Fixed Aspect Ratio", and choose a popular video dimension for your video. After you get the wanted size, write down the resolution shown in the lower-left “Crop Area Resolution.” You are going to need it later.

Alternatively, you can input the exact resolution into the Crop Area Resolution and drag the frame to crop your video. When you finish the cropping, click “OK” to go back to the main workspace.
