Digital Video

Question 20 • Introduction to Information Technology - EL3701

How does encoding affect your ability to watch digital videos?

Answer
A
To watch a digital video, you must encode it so the file size is reduced.
B
To watch a digital video, you must use the codec that was used to encode the video file.
C
To watch a digital video, it must be encoded and decoded using the H.264 encoder.
D
To watch a digital video, it must be encoded and decoded using the MPEG-4 codec.

Explanation

Encoding stores video using a particular format and compression method, and a compatible decoder is needed to play it. In other words, you need a codec that can decode the video’s encoding; it does not have to be H.264 or MPEG-4 specifically. So the correct choice is “use the codec that was used to encode the video file.”
