Video cropping FAQs

What’s the difference between video cropping and trimming?

Cropping changes the visible area of the video by removing outer parts of the frame. Trimming adjusts the video’s length by cutting from the beginning or end, affecting the duration but not the frame itself.

What’s the difference between video cropping and cutting?

Cropping modifies the visible frame to focus on specific content within the video. In contrast, cutting removes segments of the video timeline, deleting entire sections rather than altering the frame.

Does cropping a video affect quality?

Yes, cropping can reduce quality, especially if you zoom in on a small area. This may lower resolution and make the video appear pixelated or blurry.

Does cropping a video reduce file size?

Cropping alone doesn’t usually reduce file size significantly. However, the file size may decrease slightly if you export the cropped video at a lower resolution or re-encode the video after cropping.
