If you’ve read up on codecs, you’ll often see them referred to alongside containers, and it may not be instantly clear what the difference is. This is why codecs are so crucial to compression.īy converting data in this way, codecs also enable your camera, PC/laptop and editing program to download, manipulate and upload files much faster.ĭepending on the production stage you are in, it may be necessary to use particular codecs to make your files compatible with their next destination (e.g., NLE or online video platform). Moreover, they can do so often without sacrificing noticeable quality. Why codecs are so important to filmmakers comes down to 3 main reasons:Ĭodecs can be used to significantly reduce the size of raw video files so that they can be stored on SD cards or other storage devices. This process of encoding and decoding, from which the portmanteau “codec” is created (coder/ decoder), transforms raw video into a more manageable digital format (encoding) before then reverting it back to a viewable form when needed (decoding). In short, a codec is essentially software designed to encode and decode data in a particular manner. What are codecs, and why do you need them? While you can get quite far without understanding codecs, once you do, you’ll be able to take full advantage of them to boost your production workflow.
However, many filmmakers don’t actually know what codecs are or how they work. While you apply creativity and practical skill to get the right shot or edit a video together, the codecs working in the background make capturing, manipulating and sharing those videos possible. Codecs are the silent heroes of video production.
