Join Tom Green for an in-depth discussion in this video Investigating codecs, part of Learning HTML5 Video.
As you learned in the previous video, a video resides in the container or box…which holds the audio and video tracks. In this video, we open the box and poke…around at the contents. If you have ever shot a RAW video or…produced a RAW audio file and then brought it over to your computer.…You know the file size is well, massive doesn't even begin to describe it.…When you flame up a video on your computer, the video player is very, very…busy because it has to open the container to look at the audio and the video track.…
To figure out how to decode the audio and the video.…It has to decode the video and start putting the images up on the screen.…And it has to decode the audio and send that piece of the puzzle to your speakers.…Which is why the graphic of a key here, it is the piece of the puzzle that pulls it…all together when it comes to working with video.…You may notice the word Decode, it is there for a reason because the two tracks…in the package are compressed in a particular manner.…Coded and uncompressed, decoded at run time.…
