Video file size refers to the amount of digital storage space occupied by a video file. It is typically measured in gigabytes (GB) or megabytes (MB). Larger video file sizes require more time to upload, especially if the upload speed is not sufficiently fast.

The video file size is influenced by various factors, including the video resolution, frame rate, and compression settings. Higher resolution and frame rate, as well as lower compression, tend to result in larger file sizes.

To reduce video file sizes, one can consider optimizing the video format, resolution, frame rate, or utilizing video compression techniques without significant loss of quality.
