Why we crop MP4? Be it Facebook videos, Instagram Stories, Twitter posts, or IGTV, they all display the uploading MP4 video in their preferred aspect ratio. In addition, despite all the care and attention we put into recording our videos, there are bound to be black bars, strangers, and other unneeded objects. Cropping those clips is the easiest way to remove unnecessary content and the resulting MP4 clips are very possibly smaller and have new aspect ratios. Then,

Intro: How to Crop MP4 Video

Generally, there are 4 types of software you can utilize to crop an MP4 video:

Tips on Cropping MP4 Videos

Before exporting your video to the hard drive, you need to preview the same. In this way, you can ensure that the video doesn't get excessively cropped.

The chosen output format can have a big role to play in determining the quality of the cropped MP4. Thus, if you select small dimensions but set the output as a large one, then the resulting quality won't be good.

The cropped video's aspect ratio needs to be the same as the selected output format. Some of the most common aspect ratios are 16:9 (YouTube channel art, YouTube video thumbnails, Facebook cover photo), 4:3 (Instagram posts, Pinterest pins), and 1:1 (Facebook square ads, YouTube channel icon, Pinterest pins).

This versatile tool can also offer you a plethora of video editing functions such as cutting, splitting, merging, trimming, rotating, adding/removing subtitles, adding effect, adding watermark, stabilizing, and denoising video, correcting fisheye distortion and many more. An easy to use interface further adds up to the lucrativeness of VideoProc Converter AI which can easily help amateur users come up with professional results.
