The DV codec is used by MiniDV and DVCAM camcorders to capture digital video. As I reiterate throughout this chapter, always try to get the highest-quality source file available. With each decompression and recompression, there is a loss of quality called generation loss. However, these formats usually introduce low bit rate compression to the video material, and further recompression into another video format reduces the quality of the image. Other formats, such as Windows Media Video (WMV), can be recompressed into other video formats. Most video encoders accept more than just MOV and AVI files.

I define a source video file as any file you want to compress to another video file format. You can also use the MPEG specification as a file format (MPEG or MPG files), especially for High Definition Video or DVD Video files. Source video files, which are stored in a way specific to a codec, are commonly saved in Apple QuickTime (MOV files) and Microsoft Video for Windows (AVI files). Luckily, since Flash Player 6, at least one video codec has been built into the player engine-the video codecs used by Flash-compatible video aren’t downloaded as separate files like they are with other video platforms or players.

Video files don’t contain the codec used to create them the operating system or video-player application must have the codec installed in order to play back the video file.

Some codecs are used for professional video editing and output for TV broadcast, whereas other codecs are designed for low bit rates-ideal for video delivered over slower networks such as the Internet or mobile phone networks. The term codec stands for compression and decompression: The source image is compressed during acquisition or capture and is later decompressed during playback.Ī wide variety of video and audio codecs are available. When video is converted to, or acquired in, a digital format, a codec is used to effectively analyze the information in the video image and store that information on the digital tape, drive, or disc acquisition media. Distinguishing Source Files and Their DifferencesĬhapter 2, “Capturing and Processing Video,” talked about the various video acquisition formats and their quality differences.

In this chapter, you’ll learn how to make the right decisions when it comes time to compress digital video and audio into Flash-compatible video files. Compression is here to stay, so you need to know how to achieve the best results with the tools at your disposal. Storage is limited, and network bandwidth is even more so. Even with fast, fancy computers and digital devices, digital video requires a lot of bits and bytes-there’s no way to avoid throwing away visual and audio information.
