Coder-Decoder

Answer

Codec stands for Coder-Decoder, a software algorithm that compresses video data for storage/transmission and decompresses it for playback.

Question 2

What is the difference between 'lossy' and 'lossless' compression?

Accepted Answer

Lossy permanently discards data to reduce file size; lossless reduces file size without data loss

Answer

Lossy compression permanently removes data to achieve smaller file sizes (e.g., H.264), while lossless compression reduces size without discarding any data (e.g., ProRes 4444).
