Part 5. Extended Knowledge of SWF and FLV

ShockWave File or SWF is an Adobe format, but Macromedia created it. It is known for keeping vector-based animations and sounds used on the web. Moreover, because it is a vector base, you can easily adjust the graphic scaling to fit or zoom in. Other than the vector animation, the file size is so tiny to load the video faster even though you have a slow internet connection. But the format isn't supported if you desire to share them on the video-sharing platforms.

Although FLV is also under Adobe, this format is better than SWF. FLV or FlashVideo Format is the standard video format on most websites. This format can contain two different codecs intended for video and audio. And just like the SWF file, this format is small to load the file faster on the web; once you download the FLV file on your drive, you can play it on your media player even if it isn't complete yet.

It would help if you converted the SWF to FLV because the SWF has a lot of imperfections that you can find on the FLV format. Especially if the video file is lengthy, as .swf only can contain a limited frame per second, there will be a chance that you can't use it. But FLV can hold long videos with ease. Moreover, if you want to focus on quality-wise, FLV has better quality than SWF.
