As the main file format for streaming video on the Internet, the FLV format has many great advantages. It is progressive and it allows the player to start playing the video even when the whole file has not downloaded yet, something that is very convenient when loading long videos over the Internet. In addition, the FLV file format encodes videos in lossy formats so that you can have as small a file size as possible for faster loading.
Compared to FLV, the SWF format has a few shortcomings that make it not a good choice to delivery video on the Internet. First, it use lossless compression to maintain the image quality that it uses in animations and interactive applets, which means the video stored in SWF file will not be compressed and would be too big for use in the Internet. It is also not possible to store very longs videos inside the SWF file since the SWF files are limited to a certain number of frames.
