No lazy at first i didnt want to download when it said 4. Don't skip it because you are lazy. Myrk Dying from moe overdose. Apr 25, Simply saying "I can't play my multimedia file, so I need a codec," doesn't answer the next logical question: "Which codec do I need?
However, life on the Internet is never simple or easy, meaning there are scads of other codecs that have been developed. And this leads us to codec packs and their function. Sometimes your best bet is to grab a codec pack that stuffs a bunch of different codecs into one easy package. It may seem like overkill since you will end up with codecs you likely will never use, but it saves you time and frustration when searching for an arcane codec.
Following are examples of some of the more popular and reliable codec packs available today:. As the name implies, a codec performs two jobs: first, it compresses the size of the audio or video file, and second, it decompresses it as needed. All codecs employ an algorithm to accomplish this feat of decreasing large file sizes with the ability to later retrieve and display the data with similar quality as was originally recorded. However, this does not mean there is a "default" algorithm for performing the compressing of file sizes; each codec utilizes its own technology for creating the ideal algorithm for given applications.
Furthermore, each codec can choose to encode files in one of two methods: lossy or lossless compression. Lossy compression works by removing extraneous bits of information that do not impact the overall quality of the content.
For instance, an MP3 music file can use lossy compression quite effectively by extracting sounds that cannot be heard by the human ear and consequently barely affects the quality of the overall sound.
Another example is a JGP image file; it too deletes excess information or converts such information in a palatable context; for instance, a true picture with a full blue sky will generate many gradients of blue but can be easily reduced to one of two shades of blue. In lossy compression, the user typically can select the extent of the file compression technique, but higher compression resulting in smaller file sizes produces lower-quality content; a user may resort to trial and error to determine the best compression percentage while retaining an acceptable quality of content.
Lossless compression is geared more towards preserving content quality, meaning file sizes will not be as small as under lossy compression but no valuable data is tossed out in the compression process; instead, compression is accomplished by removing redundancy. While this sounds very much like removing data in lossy compression, it actually converts the data to logical sub-units. Here is an explanation of how lossless compression can work.
