I believe many people enjoy watching movies online like me. It’s certainly not necessary to download a video when seeing it, but in some cases, you might run into ASF video and have a copy of it. ASF file allows users to play videos when only a minimum number of bytes are received and downloading continues in the background while one is watching videos. However, its lower resolution forces me to look for a more popular video format, to satisfy a better viewing experience.

Usually, you can convert ASF to AVI using freeware online or using third party software. I will give you 4 options to convert ASF to AVI in the followings.

Part 5. Extended Knowledge for ASF and AVI Format

ASF, short for Advanced Systems Format, is Microsoft’s proprietary digital audio/digital video container format, especially meant for streaming media. The most common media contained within an ASF file are Windows Media Audio (WMA) and Windows Media Video (WMV).
AVI, short for Audio Video Interleave, is also developed by Microsoft. The data contained in the AVI files may be encoded in codecs, allowing the files to use less compression than other video file formats.
As mentioned above, ASF files has its advantage for being able to play videos when a minimum number of bytes are received but this is at the expense of losing some quality on resolution. On the contrary, AVI is able to retain the original file quality after conversion and is internationally used format compatible with almost all video players. That’s the main reason for users to convert ASF to AVI.
