Advanced Streaming Format, or more commonly known as ASF is a digital audio and video container format developed by Microsoft. This specific file type usually contains WMA and WMV files which allow users to continuously stream both audio and video contents in just one file. Microsoft created ASF to support the growing numbers of digitally streamed media contents such as those on YouTube, DailyMotion, Vevo and many more.
Although ASF files are usable, this multimedia format has its own share of disadvantages. One is that the maximum supported resolution is very low. At 352 by 288, you can’t expect ASF videos to be pixelated. It looks grainy even when played on small multimedia gadgets such as smartphones. Due to badly designed aspect, most people still prefer MP4 rather than ASF.
Luckily, how to convert ASF to MP4 is very easy. Hailed as the king of formats, MP4 is smaller in file size without sacrificing both audio and video quality. Additionally, MP4 is more flexible than ASF because it can be played on a wide variety of gadgets including smartphones, tablets, laptops, etc. without the need to install additional codecs.
