Part 4: Q&As about Resizing Video File

1. Is cropping the same as trimming?

No, they are different. To crop means to remove the unwanted aspect ratio (area) from your video clip or change the dimension of the file. The cropping process allows you to choose the part of the video displayed to your audience, thereby adjusting the edges for the audience to pay more attention to what is important.

On the other hand, trimming means cutting away the beginning of a video or the end of a video to reduce the length and size of the video file. Trimming helps make sure that your video starts from where your viewers will gain interest and not get bored while watching the video.

Twitter 16:9
Pinterest 16:9 (widescreen), 1:1 (square)
