“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 an often-used skill in video editing. Yet, whatever method you try, quality loss is inevitable when you crop a video. Why does cropping reduce quality? Two main reasons.
1. The pixels will lose.2. The video will be re-encoded.
Like cropping an image, you are removing parts of the video that contain the pixels to fill up the original frame. If the cropped video is to be displayed at the original size, you may quickly notice a quality drop. This is like when you enlarge/zoom in on a video and you can see all things just go fuzzy. On the other hand, video cropping, as well as many other video editing, involves re-encoding where a quality loss will happen again.
There’s no way around this. But if you can accept some quality loss, you can try to minimize the damage to a degree that you may not even see a difference. And the possible solution is to encode the video with a high-efficiency codec, such as H264 and HEVC, and export the video as it is without upscaling. In the next part, you can learn more details about how to crop a video with minimal quality loss.
HD Video Converter Factory Pro provides an excellent video cropping tool that can help you easily crop video to your wanted size while keeping the highest quality. It supports all mainstream videos and offers a wide range of export options.
As what’s mentioned before, you need to use an advanced encoder to ensure minimal impact on quality and then export the cropped video at the cropped size. A professional video editor & converter WonderFox HD Video Converter Factory Pro can help you with this. This software can let you easily crop videos to any size. And it gives you lots of controls over the output settings, including the encoding method, resolution, bitrate, frame rate, etc. With this program, you are able to crop videos without losing much quality.
Launch HD Video Converter Factory on your PC and open the “Converter” program. Next, drag your video into the blank interface.
At the bottom of the program, you can set an output folder in advance.
In the video conversion list, click the “Crop” button to open the Crop window. The default editing mode is set to “Free Aspect Ratio,” and you should leave it like that. Then, on the left “Original Preview,” adjust the frame to crop the video as you want. You can preview the real-time effect on the right “Output Preview.” After you get the wanted effect, 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.
Now, click to open the right-side output format page and go to the “Video” section. Choose “H265 for MP4” as the output format as H265/HEVC can maintain video at relatively high quality even in a low bitrate.
Next, open the “Parameter settings” below and find the “Resolution” option. Click “Customize” and type in the Crop Area Resolution. Click “OK” to save the changes.
Finally, click “Run” to export the cropped file.
If you don’t need to edit the video but simply want to watch the video at your wanted size, you can use your video player to crop while playing. This won’t generate an output file, though. The video player you can try is VLC Media Player, which has an in-built crop feature.
For many video content creators, quality usually matters the most in video editing. Whatever you’re going to do with your video, you want to do it gently without impacting the quality. Now that video cropping is often needed. Is it possible to crop a video without losing quality? Or how can you crop videos with the best quality?
