ASF videos were all the rage when Windows Media Player was still alive. Since then, ASF has faded into antiquity. Today, it's a relic from the past, long buried in Microsoft's legacy tools. Without Windows Media Player, ASF videos are just sitting there on your desktop without any tool to play them. Does that mean all video content in ASF files is lost forever? Of course, not! You can convert ASF to MP4 format and preserve all your video content. Converting ASF videos to MP4 format makes them future-proof and ensures compatibility with all major video players. In this guide, you'll learn all the basics of ASF to MP4 conversion and get some pro tips to ease your task.

Part 1: What is the ASF Format?

ASF is a video container format developed by Microsoft for streaming media. Generally, files using .ASF extension contain video and audio content, but they may also contain only audio content too. While Microsoft developed the file format for streaming from media servers and HTTP servers, they are suitable for local playback too. In many cases, video games and DVRs also use the ASF file format.

Since ASF is Microsoft's proprietary video format, it's not widely compatible. In fact, most video players do not support it. Even social media platforms like YouTube, Twitter, Discord, etc. do not support the ASF file format. For broader compatibility and convenient distribution, ASF videos must be converted to a mainstream format like MP4.

Part 2: How to Batch Convert ASF to MP4 with HitPaw Univd

Whether it's because ASF is a proprietary format or it's outdated, the format is not supported by many mainstream video converters. Univd Video Converter is one of the few tools that continues to support the ASF file format. With Univd, you can quickly and easily convert ASF file to MP4 or any other video file format. It's the only tool you need to future-proof all your video content.

Part 3: How to Convert ASF to MP4 with VLC Media Player

VLC Media Player is a free and open-source media player with surprisingly powerful video conversion capabilities. It's also one of the few media players and video converters that natively support the ASF video format. VLC's familiar interface, owing to its widespread popularity, makes it a convenient ASF to MP4 converter for many users. However, despite the batch conversion capabilities, VLC is not a full-fledged video converter, so user-friendliness is not one of its strengths.

FAQs on ASF to MP4 Conversion

Q1. What if I only hear audio and see no video after converting my ASF file to MP4?

A1. Some ASF files contain only audio, so, naturally, conversion to MP4 will result in only the audio playing without any video. You can verify this by playing the original ASF file in VLC Media Player. If you can see both audio and video in the ASF playback but only audio playback in the MP4 file, then it's likely because the conversion tool made an error. You can switch to a different file converter to address the issue.

Q2. Can I edit ASF files during conversion to MP4?

A2. Yes. Some video converters like HitPaw Univd let you add and remove subtitles, edit videos, change metadata, and do more during conversion.

Q3. Is it legal to convert ASF to MP4?

A3. If you have ownership of the ASF video, then it's perfectly legal. However, if it's a copyrighted video, the legal implications may get complex. In general, if you're converting video files for personal use, that shouldn't be a problem. However, for distribution purposes, file conversion of copyrighted content would be illegal. Check your local laws to ensure legal compliance.

Conclusion

While there are many ways to convert ASF to MP4, HitPaw Univd offers a high-performance solution. Univd produces high-quality output, preserves the original quality of ASF videos, and converts thousands of videos at once. Check it out today.
