We crop videos to cut unwanted parts, trying to focus audience’s attentions or fit the video to different streaming platforms. A video cropping is often processed with a certain aspect ratio. For a Mac user, cropping video can be done with iMovie—the free video editor preinstalled in macOS. Today, we will show you 6 easy ways to crop a video in MP4 or other formats on Mac, and make your videos fancy.

1. Easily Crop A Video on Mac with Any Aspect Ratio

I used to be a iMovie heavy user since the year of 2015 when I had my first Mac, it was absolutely the best free video editor these years, but as my video editing skills advanced and my needs to create videos becomes diversified, I switched to a professional video editor for cropping or other video editing needs. In addition, online free video cropping tools are limited in features or come with a watermark. Therefore, most of us finally bounce out to a paid video editor expert to crop or edit videos on Mac.

4. Can We Crop Video on Mac in VLC?

I notice that some users tried to crop videos on Mac with VLC player, however, I failed after several testing.

VLC media player does have a Crop feature in its video toolbar, but you can only crop video in the playing, there is no option offered to save the cropped video. In other words, VLC cannot crop a video permanently.

Also, I tried to follow the videos to crop video in VLC by tweaking video effects, preferences, video cropping filter. When I tried to export the video, I am not allowed to use the video-cropping filter, therefore, I cannot crop videos in VLC.vlc crop 05
