An AVI file usually has a ____ file size
A
small
B
lossy
C
large
D
compressed
Explanation: 

Detailed explanation-1: -The result is a huge file size of 2-3 GB per minute of video on average. This is a problem for users with limited storage space. However, AVI files can be compressed by converting them to other formats such as MOV, FLV or MP4.

Detailed explanation-2: -When it comes to file sizes, AVI files are considerably larger than MP4. But you can compress AVI files to make them smaller or convert them to other formats such as FLV or even MP4. MP4, on the other hand, is a lossy video container occupying less space than its AVI counterpart.

Detailed explanation-3: -"Full-resolution” video is typically captured at 640 x 480 resolution, 640 pixel dots across by 480 lines of pixels down. Just one frame is 900 KB of data, or almost enough to fill one floppy disk. Video clips designed to be played on a PC are typically stored at half resolution, or 320 x 240.

Detailed explanation-4: -AVI is smaller in size. The size difference is due to the compression features available as it does minimal compression keeping the subtle details. On the other hand, MKV makes larger files. So, it troubles uploading the file on digital platforms like YouTube.
