Feedback

Compression aims to shrink file size, sometimes at the cost of quality.

Loss of some quality is a common trade-off with compression.

A codec handles compression and decompression of data.

Higher resolution in HD makes images appear clearer.

Dedicated digital video cameras typically offer superior quality.

Uncompressed audio preserves quality but results in larger file sizes.

MP3 is a common lossy compressed audio format.

WAV is uncompressed or high-quality, demanding more storage.

Codecs enable efficient storage by compression and decompression.

HD video has higher resolution than SD, improving clarity.
