Text compression techniques
However, MP4 is a lossy format.
This means that every time you save the same audio or video file as an MP4, you lose a little bit of data, and thus a little bit of quality.
If you re-save an MP4 file enough times, eventually, the quality will be unrecognizable.
This is a very rare occurrence, but it does happen..
Text compression techniques
Lossy methods can provide high degrees of compression and result in smaller compressed files, but some number of the original pixels, sound waves or video frames are removed forever.
Examples are the widely used JPEG image, MPEG video and MP3 audio formats..
What data types are lossless compression?
Lossless compression file types.
PNG.
This is a pixel-based image format that offers high-quality graphics. BMP.
Another image file type used for storing and printing high-quality digital photos. RAW.
These powerhouse files are one of the most common camera image formats. GIF. ZIP. WAV..What data types are lossy?
DCT is the most widely used form of lossy compression, for popular image compression formats (such as JPEG), video coding standards (such as MPEG and H. 264/AVC) and audio compression formats (such as MP3 and AAC)..
