What Kind of Problems Do You Have When Cropping Videos?

Dylan: Movie Lover

I have been removing black bars from videos with VLC for a while, but it only works when playing the video and doesn’t save. And I’ve tried the built-in croppers on the computer to crop movies, but in the end, there were still black bars cause the croppers perform inaccurately. It has been baffling me for a while, and now I have no solution.

Jill: TikTok, Dance Blogger

Previously, I filmed my first dance and was ready to upload the dance video on TikTok, but the video can not fit the TikTok’s frame, so I tried cropping the video with iMovie, but then there was another problem: some of my amazing actions were over the new frame. Is there any smart cropper to seize the main subject in videos?
