Within a particular container type, such as Quicktime or AVI, there can be a vast difference between the video signal attributes, the codecs used, and the compression. Video files are particularly complex internally, but they all need to be stored in one of the basic container types. And nearly every computer file has more than one type of data inside the file. Let’s dive in, starting from the outside and peel back the layers.Īll file formats are structures for bundling up some type of data.
